The Offering

  Common Stock offered by selling shareholders                   500,000 shares
  Shares underlying stock options held by selling shareholders 3,000,000 shares
  Common Stock to be outstanding after the offering, based on
    shares outstanding on March 11, 2005                      10,067,172 shares
  American Stock Exchange symbol                                            AEY

     No shares are being offered or sold by us either directly or through
options or warrants.  The options have been granted to Barron Partners, L.P. by
David Chymiak and Kenneth Chymiak.  Thus, neither the sale of any of the
offered shares nor exercise of the options will result in an increase in the
numbers of outstanding shares of our common stock.  The total of 10,067,172
shares of common stock to be outstanding after this offering is based on the
number of shares outstanding on March 11, 2005.

     This is a continuous offering and is not underwritten.  We cannot predict
when or if the selling shareholders will sell their shares or exercise options
entitling them to purchase and possibly sell shares underlying the options.
This offering assumes that the selling shareholders will exercise all options
they hold for purchase of our common stock, for cash and at the current
exercise price.
       
                                 RISK FACTORS

     You should carefully consider the following risk factors, in addition to
the other information set forth in this prospectus, before deciding to purchase
any shares of our common stock.  Each of these risk factors could adversely
affect our business, operating results and financial condition, as well as
adversely affect the value of an investment in our common stock.  Additional
risks not presently known, or which we currently consider immaterial also may
adversely affect us.

We are highly dependent upon our principal executive officers who also control
us.


     At March 14, 2005, David Chymiak, Chairman of the Board, and Kenneth
Chymiak, President and Chief Executive Officer, owned approximately 69.5% of
our outstanding common stock and 100% of our outstanding preferred stock.  Our
performance is highly dependent upon the skill, experience and availability of
these two persons.  Should either of them become unavailable to us, our
performance and results of operations would probably be adversely affected to a
material extent.  In addition, they will continue to own a controlling interest
in us, thus restricting our ability to take any action without their approval
or acquiescence.  Likewise, as shareholders, they may elect to take certain
actions which may be contrary to the interests of the other shareholders.

Our business is dependent on our customers' capital budgets.


     Our performance is impacted by our customers' capital spending for
constructing, rebuilding, maintaining or upgrading broadband communications
systems. Capital spending in the telecommunications industry is cyclical. A
variety of factors will affect the amount of capital spending, and therefore,
our sales and profits, including:

     *consolidations and recapitalizations in the cable television industry;
     *general economic conditions;
     *availability and cost of capital;
     *other demands and opportunities for capital;
     *regulations;
     *demands for network services;
     *competition and technology; and
     *real or perceived trends or uncertainties in these factors.

                                   4


     Developments in the industry and in the capital markets in recent years
have reduced access to funding for certain customers, causing delays in the
timing and scale of deployments of our equipment, as well as the postponement
or cancellation of certain projects by our customers.

     On the other hand, a significant increase in the capital budgets of our
customers could impact us in a negative fashion.  Much of our inventory
consists of refurbished and surplus-new equipment and materials that we have
acquired from other cable operators.  If our customers seek higher end, more
expensive equipment, the demand for our products may suffer.

The markets in which we operate are very competitive, and competitive pressures
may adversely affect our results of operations.

The markets for broadband communication equipment are extremely competitive and
dynamic, requiring the companies that compete in these markets to react quickly
and capitalize on changes.  This will require us to make quick decisions and
deploy substantial resources in an effort to keep up with the ever-changing
demands of the industry.  We compete with national and international
manufacturers, distributors, resellers and wholesalers including many companies
larger than we are.

     The rapid technological changes occurring in the broadband markets may
lead to the entry of new competitors, including those with substantially
greater resources than we have.  Because the markets in which we compete are
characterized by rapid growth and, in some cases, low barriers to entry,
smaller niche market companies and start-up ventures also may become principal
competitors in the future. Actions by existing competitors and the entry of new
competitors may have an adverse effect on our sales and profitability. The
broadband communications industry is further characterized by rapid
technological change. In the future, technological advances could lead to the
obsolescence of a substantial portion of our current inventory, which could
have a material adverse effect on our business.

Consolidations in the telecommunications industry could result in delays or
reductions in purchases of products, which would have a material adverse effect
on our business.

     The telecommunications industry has experienced the consolidation of many
industry participants, and this trend is expected to continue. We and one or
more of our competitors may each supply products to businesses that have merged
or will merge in the future. Consolidations could result in delays in
purchasing decisions by the merged businesses, and we could play either a
greater or lesser role in supplying the communications products to the merged
entity. These purchasing decisions of the merged companies could have a
material adverse effect on our business. Mergers among the supplier base also
have increased, and this trend may continue. The larger combined companies with
pooled capital resources may be able to provide solution alternatives with
which we would be at a disadvantage to compete. The larger breadth of product
offerings by these consolidated suppliers could result in customers electing to
trim their supplier base for the advantages of one-stop shopping solutions for
all of their product needs. Consolidation of the supplier base could have a
material adverse effect on our business.

Our success depends in large part on our ability to attract and retain
qualified personnel in all facets of our operations.


     Competition for qualified personnel is intense, and we may not be
successful in attracting and retaining key executives, marketing, engineering
and sales personnel, which could impact our ability to maintain and grow our
operations. Our future success will depend, to a significant extent, on the
ability of our management to operate effectively.  The loss of services of any
key personnel, the inability to attract and retain qualified personnel in the
future or delays in hiring required personnel, particularly engineers and other
technical professionals, could negatively affect our business.

We are substantially dependent on certain manufacturers, and an inability to
obtain adequate and timely delivery of products could adversely affect our
business.

     We are a value added reseller and master distributor for Scientific-
Atlanta and a value added reseller of Motorola broadband and transmission
products.  Should these relationships terminate or deteriorate, or should
either manufacturer be unable or unwilling to deliver the products needed by us
for our customers, our performance could be adversely impacted.  An inability
to obtain adequate deliveries or any other circumstance that would require us
to seek alternative sources of supply could affect our ability to ship products
on a timely basis. Any inability to reliably ship our products on time could
damage relationships with current and prospective customers and harm our
business.
                                    5


We have a large investment in our inventory which could become obsolete or
outdated.

     Much of our inventory is acquired from other cable operators and is in the
nature of used, refurbished, remanufactured or surplus new equipment.
Determining the amounts and types of inventory requires us to speculate to some
degree as to what the future demands of our customers will be.  Technological
changes, consolidation in the industry or competition from other types of
broadcast media could substantially reduce the demands for our inventory, which
could have a material adverse effect upon our business and financial results.

Our outstanding common stock is very thinly traded.

     While we have approximately 10.1 million shares of common stock
outstanding, 69.5% of these shares are beneficially owned at March 14, 2005 by
David Chymiak and Kenneth Chymiak and 2.1% are beneficially held by Barron
Partners, L.P.  As a consequence, only about 28% of our shares of common stock
are held by nonaffiliated, public investors and available for public trading.
The average daily trading volume of our common stock is low.  Thus, investors
in our common stock may encounter difficulty in liquidating their investment in
a timely and efficient manner.
 

We have not paid any dividends on our outstanding common stock and have no
plans to pay dividends in the future.

     We have not paid any dividends on our common stock.  We currently plan to
retain our earnings and have no plans to pay dividends on our common stock in
the future. We may also enter into credit agreements or other borrowing
arrangements which may restrict our ability to declare dividends on our
common stock.

Our principal executive officers and shareholders have a number of conflicts of
interest with us.

     Certain of our key properties are leased from entities owned by our
principal executive officers.  Also, these executives have made loans to us in
various amounts in the past and were paid interest on these loans. These
transactions are described in the proxy statement that is incorporated by
reference into this report. These arrangements create certain conflicts of
interest between these executives and us that may not always be resolved in a
manner most beneficial to us.

Our international operations may be adversely affected by a number of factors.


     Although the majority of our business efforts are focused in the United
States, we have international operations in the Philippines, Taiwan, Korea,
Japan, Australia, Brazil, Ecuador, Dominican Republic, Honduras and a few other
Latin American countries.  We currently have no binding agreements or
commitments to make any material international investment.  Our foreign

                             SELLING SHAREHOLDERS
Background

     On September 24, 2004, David E. Chymiak, our Chairman of the Board and
owner at that time of approximately 41.5% of our outstanding common stock and
50% of our outstanding preferred stock, and Kenneth A. Chymiak, our President
and Chief Executive Officer and owner at that time, together with his wife, of
approximately 37.6% of our outstanding common stock and 50% of our outstanding
preferred stock, entered into a stock purchase agreement with Barron Partners,
L.P., a Delaware limited partnership whose main offices are in New York,
New York, pursuant to which Barron Partners agreed to purchase from the
Chymiaks 500,000 shares of our common stock at a price of $3.25 per share.
In the same agreement, Barron Partners was also granted the options described
below.  As of the date of this amended prospectus, Barron Partners purchased an
additional 500,000 shares through partial exercises of Option No. 1.  As of
March 14, 2005, David E. Chymiak owned 36.7% of our outstanding common stock
and 50% of our outstanding preferred stock, and Kenneth A. Chymiak together
with his wife owned 32.8% of our common stock and 50% of our outstanding
preferred stock.  As of March 14, 2005, the 213,000 shares owned by Barron
Partners represented approximately 2.1% of our outstanding common stock.
Bathgate Capital Partners, LLC received a fee of $97,500 in connection with the
sale of the 500,000 shares, a combined fee of $115,000 in connection with the
sale of 500,000 shares upon partial exercises of Option 1 by Barron Partners,
and will receive additional fees if and to the extent that additional options
are exercised.

     Under the stock purchase agreement, Barron Partners was also granted three
options to buy up to an additional 3,000,000 shares of common stock from the
Chymiaks.  The terms of these options are summarized as follows:


       
       Option   No. of Shares     Exercise Price      Expiration Date*
       ------   -------------     --------------      ----------------
       No. 1      1,000,000           $4.25
       No. 2      1,000,000           $5.25
       No. 3      1,000,000           $6.25



*   The expiration date will be extended during any period that Barron Partners
is not able to sell shares under the registration statement of which this
prospectus is a part.

     Each option can be exercised at any time in whole or in part, except that
each exercise must be for a minimum of 150,000 shares.  The stock purchase
agreement provides that the options are not exercisable to the extent that
shares received upon exercise, when added to the shares that Barron Partners
then beneficially own, would represent more than 4.99% of our outstanding
shares.  This restriction can be eliminated by Barron Partners upon 61 days'
prior written notice.  The 3,500,000 shares covered by the stock purchase
agreement represent approximately 34.8% of our outstanding shares of common
stock.

     All of the shares which Barron Partners have purchased and which it has
the right to acquire under the terms of the stock purchase agreement, including
the shares which they are entitled to receive upon exercise of the options, may
be offered for sale from time to time by the selling shareholders pursuant to
this prospectus.  The term "selling shareholders" as used in this prospectus,
includes Barron Partners, L.P. and their transferees, pledges, donees and other
successors acquiring an interest in the shares after the date of this
prospectus.

                                     7


     The selling shareholders are not obligated to sell their shares.  If they
do sell their shares, they may be sold pursuant to this prospectus or in
another permitted manner.  Thus, no assurances can be given as to the number of
shares that may be sold by the selling shareholders or that will be held by
them upon completion of the sales.  Information concerning the selling
shareholders may change from time to time and the changed information will be
presented in a supplement to this prospectus if and when necessary and
required.  We do not know whether or when the options will be exercised or how
long the selling shareholders may hold their shares before selling them.  We
currently have no agreements, arrangements or understandings with any of the
selling shareholders regarding sales of their shares.

     Barron Partners, L.P. has not had a material relationship with us or any
of our subsidiaries within the past three years.  They also have sole voting
and investment power with respect to the shares that they acquire pursuant to
the stock purchase agreement.


                             PLAN OF DISTRIBUTION

     We are registering the offer and sale of the shares covered by this
prospectus on behalf of the selling shareholders.  As used in this prospectus,
the term "selling shareholders" includes donees, pledges, transferees or other
successors-in-interest selling shares received from a selling stockholder after
the date of this prospectus.  The selling shareholders will act independently
of us in making decisions with respect to the timing, manner and size of each
sale.

     The selling shareholders may sell their shares from time to time in one or
more types of transactions (which may include block transactions) on the
American Stock Exchange, in the over-the-counter market, in negotiated
transactions, through put or call options transactions relating to the shares,
through short sales of shares, or a combination of these methods of sale, at
market prices prevailing at the time of sale, at negotiated prices, or at
varying prices determined at the time of sale.  These transactions may or may
not involve brokers or dealers.  The selling shareholders have advised us that
they have not entered into any agreements, understandings or arrangements with
any underwriters or broker-dealers regarding the sale of their shares, nor is
there an underwriter or coordinating broker acting in connection with the
proposed sale of shares by the selling shareholders.

     The selling shareholders may sell their shares directly to purchasers or
to or through broker-dealers, which may act as agents or principals.  These
broker-dealers may receive compensation in the form of discounts, concessions,
or commissions from the selling shareholders and/or the purchasers of shares
for whom these broker-dealers may act as agents or to whom they sell as
principal, or both (which compensation as to a particular broker-dealer might
be in excess of customary commissions).

     The selling shareholders also may resell any of their shares that qualify
for sale under Rule 144 in open market transactions pursuant to Rule 144 under
the Securities Act, rather than pursuant to this prospectus.

     The selling shareholders and any broker-dealers that act in connection
with the sale of their shares might be deemed to be "underwriters" within the
meaning of Section 2(11) of the Securities Act, and any commissions received by
these broker-dealers and any profit on the resale of the shares sold by them
while acting as principals might be deemed to be underwriting discounts or
commissions under the Securities Act.  We have agreed to indemnify the selling
shareholders against certain liabilities, including liabilities arising under
the Securities Act.  The selling shareholders may agree to indemnify any agent,
dealer or broker-dealer that participates in transactions involving sales of
their shares against certain liabilities, including liabilities arising under
the Securities Act.

     Because the selling shareholders may be deemed to be "underwriters" within
the meaning of Section 2(11) of the Securities Act, the selling shareholders
will be subject to the prospectus delivery requirements of the Securities Act.
We have informed the selling shareholders that the anti-manipulative provisions
of Regulation M promulgated under the Exchange Act may apply to their sales in
the market.

     Upon notification to us by a selling stockholder that any material
arrangement has been entered into with a broker-dealer for the sale of shares
through a block trade, special offering, exchange distribution or secondary
distribution or a purchase by a broker or dealer, a supplement to this
prospectus will be filed, if required, pursuant to Rule 424(b) under the
Securities Act, disclosing:

     * the name of the selling stockholder and of the participating
       broker-dealer(s);
     * the number of shares involved;

                                     8


     * the price at which the shares were sold;
     * the commissions paid or discounts or concessions allowed to the
       broker-dealer(s), where applicable;
     * that the broker-dealer(s) did not conduct any investigation to verify
       the information set out in this prospectus; and
     * any other facts material to the transaction.

     We will pay all the costs, expenses and fees related to the registration
of the shares offered by this prospectus.  The selling shareholders will be
responsible for the payment of any brokerage commissions, underwriting fees or
discounts or fees or expenses of counsel or advisors attributable to the sale
of the shares.

                            DESCRIPTION OF BUSINESS

General Development of Business

     ADDvantage Technologies Group, Inc. is an Oklahoma corporation that was
organized on September 20, 1989.   Prior to December 30, 1999, we were known as
ADDvantage Media Group, Inc. ("AMG").  From 1989 through much of 1998, AMG was
in the business of providing advertising services, primarily on Shoppers
Calculators(r) which are solar powered calculators that attach to the handles of
shopping carts.  AMG's operations primarily consisted of the implementation of
its Shoppers Calculators(r) program in Supercenter stores operated by Wal-Mart
Stores, Inc. ("Wal-Mart").  Substantially all of AMG's revenues in 1997 and
1998 were generated from a contract with Wal-Mart.  In 1998, Wal-Mart notified
AMG of its intent not to renew its contract and AMG began removing the
calculators from the Wal-Mart Supercenters.  Removal of the calculators was
completed in September of 1998.  A lawsuit was commenced against Wal-Mart about
the same time.  This suit was settled in July of 1999 for a nominal payment to
AMG.

     AMG began considering alternative business plans and possible business
combinations.  On September 30, 1999, the former shareholders of TULSAT
Corporation (formerly named DRK Enterprises, Inc.) assumed control of AMG
pursuant to the Securities Exchange Agreement ("Agreement") entered into on
September 16, 1999.  Pursuant to the Agreement, the TULSAT shareholders
transferred all the issued and outstanding common stock of TULSAT, along with
$10,000,000 of TULSAT promissory notes, to ADDvantage Media in exchange for
8,000,000 shares of ADDvantage Media $.01 par value common stock, 200,000
shares of newly issued Series A 5% Cumulative Convertible Preferred Stock, par
value $1.00 per share, with a stated value of $40.00 per share (convertible
into ADDvantage Media common stock at a price of $4.00 per share), and 300,000
shares of newly issued Series B 7% Cumulative Preferred Stock, par value $1.00
per share, with a stated value of $40.00 per share.

                                     9


     As a result of this transaction, TULSAT became a wholly owned subsidiary
of AMG and the former TULSAT owners acquired approximately 82% of the then
issued and outstanding common stock, and 100% of the issued and outstanding
preferred stock of AMG.  Because the TULSAT shareholders received 82% of the
common stock and all the preferred stock, TULSAT was considered the surviving
corporation and its past financial results were reported as the historical
results of AMG.  TULSAT's management assumed management and control of AMG.
The transaction was accounted for as a purchase of AMG by TULSAT.  On December
30, 1999, AMG changed its name to ADDvantage Technologies Group, Inc.

Current Business

     We are a supplier of a comprehensive line of electronics and hardware for
the cable television ("CATV") industry (both franchise and non-franchise, or
private cable).  Our products are used to acquire, distribute and protect the
broad range of communications signals carried on fiber optic, coaxial cable and
wireless distribution systems.  These products are sold to customers providing
an array of communications services including television, high-speed data
(internet) and telephony, to single family dwellings, apartments and
institutions such as hospitals, prisons, universities, schools, cruise boats
and others.

     TULSAT, one of our subsidiaries, is an exclusive Scientific-Atlanta Master
Distributor for certain legacy products and distributes most of Scientific-
Atlanta's other products.  TULSAT has been designated an authorized third party
Scientific-Atlanta repair center for selected products.  Another subsidiary,
NCS Industries, is a leading distributor of Motorola broadband products.  Other
subsidiaries distribute Standard, Corning-Gilbert, Blonder-Tongue, RL Drake,
Quintech and Videotek products.  We continue to upgrade our products to stay in
the forefront of the communications broadband technology revolution.

     We continue to expand our core product lines (head end and distribution),
to maintain the ability to provide electronics equipment needed to build
smaller cable systems and much of the equipment needed in larger systems for
the most efficient operation and highest profitability in high density areas.

     We also continue to purchase surplus equipment from cable operators and
others that become available as a result of upgrades in their systems or
overstocks in their warehouses.  We maintain one of the industries' largest
inventories of new and refurbished equipment, allowing us to provide products
within a short period of time.  Each of our six locations operates service
centers specializing in Motorola, Magnavox, Scientific-Atlanta and Alpha Power
Supplies repairs.

Overview of the Industry

     We participate in markets for equipment sold primarily to cable operators
and other related parties.  As internet usage by households continues to
increase, more customers are electing to switch from dial-up access services to
high-speed services, particularly those offered by cable operators in the
United States.  Within the last few years, certain cable operators have begun
to offer a "triple-play" bundle of services that includes voice, video and
high-speed data over a single network with the objective of capturing higher
average revenues per subscriber.  We believe cable operators are well
positioned to deliver next-generation voice, video and data services because
cable operators have invested significantly over the past few years to upgrade
their cable plants to digital networks.  These upgrades allow them to leverage
their incumbent video and high speed data positions further.  Many cable
operators have well-equipped networks to offer video and two-way high-speed
data services to over 90% of their subscribers and through their existing
Hybrid Fiber Co-axial (HFC) infrastructure, are capable of delivering
symmetrical high-bandwidth video, voice and data to their subscribers.

     For the past couple of years, we believe that we have been able to provide
the products and services sought after by cable operators as they establish and
expand their services and territories.  Our relationships with our principal
vendors, Scientific-Atlanta and Motorola, provide solutions with products that
are required to implement and support existing cable operators.  These
relationships and our inventory are key factors in our significant revenue and
profits.

     We are focused on the opportunities provided by technological changes in
fiber-to-the premises, the expansion of bandwidth, and our recent appointment
as a Scientific-Atlanta International Distributor for Latin America.  We will
continue to stock legacy CATV equipment as well as digital and optical
broadband telecommunications equipment from major suppliers so we can provide
our customers one-stop shopping and access to "hard-to-find" products by
reducing customer downtime by our having the product in stock.  Our customers
consult with us for solutions for various products and configurations.  We have
the technical know-how from our experienced sales support staff.  Through our

                                   10


six "world-class" service centers that provide warranty and out-of-warranty
repairs, we continue to reach new customers.

Business of the Company

     We continue to add products and services to maintain and expand our
current customer base in North America, Latin America, Europe and the Far East.
Recently, Scientific-Atlanta has appointed one of our subsidiaries, Tulsat
Corporation, to become one of their non-exclusive distributors in Latin
America.  Since the appointment, management has made several trips to the area,
visiting with relationships that had previously been developed by our new sales
associate for this area.  In addition, Tulsat has contracted for 12 months of
advertising in the leading magazine for the cable equipment market in this area
and Spain.

     Economics seem to be improving for the international cable operators in
Latin America.  The continuing advances in technology, products and services
will continue to create a better financial model for potential customers.  We
require prepayment of purchases or letters of credit from U.S. banks prior to
shipment of products to most international customers.  Recently, we have found
several other methods of guaranteeing payment through insurance companies or
government agencies.  The successful implementation of alternative methods of
payments should put our companies in a better position to capture market share.

     Geographic Areas

Revenues by geographic areas are as follows:

                           =============================================



Revenues attributed to geographic areas are based on the location of the
customer. All of our long-lived assets are located in the United States.

     Products and Services

     In fiscal year 2004, our sales of new products represented 70% of our
revenue and re-manufactured product sales represented 20% of our revenues.
Repair services contributed the remaining 10% of our revenues.

     In fiscal year 2003, our sales of new products represented 59% of our
revenue and re-manufactured product sales represented 27% of our revenues.
Repair services contributed the remaining 14% of our revenues.

     In fiscal year 2002, our sales of new and surplus products represented 46%
of our revenue and re-manufactured product sales represented 38% of the
revenues.  Repair services contributed the remaining 16% of our revenues.

     Headend products are used by a system operator for signal acquisition,
processing and manipulation for further transmission.  Among the products we
offer in this category are satellite receivers (digital and analog), integrated
receiver/decoders, demodulators, modulators, antennas and antenna mounts,
amplifiers, equalizers and processors.  The headend of a television signal
distribution system is the "brain" of the system, the central locations where
the multi-channel signal is initially received, converted and allocated to
specific channels for distribution.  In some cases, where the signal is
transmitted in encrypted form or digitized and compressed, the receiver will
also be required to decode the signal.

                                   11


     Fiber products are used to transmit the output of cable system headend to
multiple locations using fiber optic cable.  Among the products offered are
optical transmitters, receivers, couplers, splitters and compatible
accessories.  These products convert RF frequencies to light frequencies and
launch them on optical fiber.  At each receiver site, an optical receiver is
used to convert the signals back to RF VHF frequencies for distribution to
subscribers.

     Distribution products are used to permit signals to travel from the
headend to their ultimate destination in a home, apartment, hotel room, office
or other terminal location along a distribution network of fiber optic or
coaxial cable.  Among the products we offer in this category are optical
transmitters, optical receivers, line extenders, broadband amplifiers,
directional taps and splitters.

     Other hardware such as test equipment, connector and cable products are
also inventoried and sold to our customers.

     Sales and Marketing

     We market and sell our products to franchise and private cable operators,
system contractors and others directly.  Our sales and marketing are
predominantly performed by our internal sales force.  We also have sales
representatives in particular geographic areas.  The majority of our sales
activity is generated through personal relationships developed by our sales
personnel and executives, referrals from manufacturers we represent,
advertising in trade journals, telemarketing and direct mail to our customer
base in the United States.  We have developed contacts with the major CATV
operators in the United States and we are constantly in touch with these
operators regarding their plans for upgrading or expansion and their needs to
either purchase or sell equipment.  In 2004, we purchased approximately 39% of
our inventory from Scientific-Atlanta and approximately 14% of our inventory
from Motorola.  The concentration of suppliers of our inventory subjects us to
risk.  We also purchase a large amount of our inventory from cable operators
who have upgraded or are in the process of upgrading, their systems.

     Competition
       
     The CATV industry is highly competitive with numerous companies competing
in various segments of the market.  There are a number of customers throughout
the United States engaged in buying and selling re-manufactured CATV equipment.
Most of our competitors are not able to maintain the large inventory we
maintain due to capital requirements.  In terms of sales and inventory, we are
the largest in this industry, providing both sales and service of new and re-
manufactured CATV equipment.

     We also face competition from manufacturers and other vendors supplying
new products.  Due to our large inventory, we generally have the ability to
ship and supply products to our customers from our large inventory without
having to wait for the manufacturers to supply the items.

     Significant Customers

     We are not dependent on one or a few customers to support our business.
The customer base consists of over 1,200 active accounts.  Sales to Power and
Telephone Supply Company accounted for approximately 11.9% of our revenues in
fiscal 2004.  Approximately 23% of our revenues for fiscal year 2004 and
approximately 33% for 2003 were derived from sales of products and services to
our five largest customers.  There are approximately 6,000 cable television
systems within the United States, each of which is a potential customer.

     Personnel

     At February 28, 2005, we had 137 employees.  Management considers its
relationships with its employees to be excellent.  Our employees are not
unionized and we are not subject to any collective bargaining agreements.

     Segments

     We operate in one business segment.

                             DESCRIPTION OF PROPERTY

     From time to time in the ordinary course of business, we have become a
defendant in various types of legal proceedings.  We do not believe that these
proceedings, individually or in the aggregate, will have a material adverse
effect on our financial position, results of operations or cash flows.

                 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

Overview

     We are a Value Added Reseller ("VAR") for selected Scientific-Atlanta and
Motorola broadband new products.  We also specialize in the sale of
refurbished, previously-owned cable television ("CATV") equipment to CATV
operators and other broadband communication companies.  Within the last three
years, we have become distributors for several different manufacturers of
equipment and other related products.  It is through our development of these
relationships that that we have focused our initiative to market our products
and services to the larger cable multiple system operators ("MSOs").  As a
result, our overall sales increased for the first three months of fiscal 2005.
We continue to believe that as cable companies look at expanding their services
in key markets and to remain competitive during this period of economic
recovery, there will be an emphasis on minimizing their costs, thus creating a
higher demand for our repair services and surplus-new equipment.

Results of Operations

Comparison of Results of Operations for the Three Months Ended December 31,
2004 and December 31, 2003

Net Sales.  Net sales increased $969,000, or 8.6%, to $12.3 million in the
first quarter of fiscal 2005, from $11.3 million for the same period in fiscal
2004, primarily due to the positive results of our marketing initiatives and
distributor relationships discussed in the previous paragraph.  New equipment
sales were up 17.6% to $8.9 million for the current period, compared with $7.6
million for the same period of fiscal 2004.  Sales of remanufactured equipment
decreased by 14.8% to $2.2 million for the current period, compared with $2.6
million in the same period last year.  Repair service revenues were up 1.4% to
$1.14 million for the current quarter, compared with $1.13 million for the
same period last year.

Costs of Sales.  Costs of sales includes (i) the costs of new and refurbished
equipment, on a weighted average cost basis, sold during the period, (ii) the
equipment costs used in repairs, (iii) the related transportation costs, and
(iv) the labor and overhead directly related to these sales.  Costs of sales
increased to $7.4 million for the first quarter of fiscal 2005 from $6.7
million for the same period of fiscal 2004.  The increase was primarily due to
the increase in sales for the period.  Costs of sales for new and refurbished
equipment increased slightly to 66.3% of net sales income for 2005 from 66.1%
of net sales income for 2004.  Costs of sales for repair services increased to
72.7% of net service income for 2005 from 62.3% of net service income for 2004.
This increase was due primarily to more high-end hybrid and fiber optic
equipment being repaired, which involves a higher relative cost of material.

Gross Profit.  Gross profit climbed $186,000 or 4.8% to $4.1 million for the
first quarter of fiscal 2005 from $3.9 million for the same period in fiscal
2004.  The gross margin percentage was 33.1% for the current quarter, compared
to 34.3% for the same quarter last year.  The percentage decrease was primarily
due to an increase in sales of new and surplus equipment, which are accompanied
by margins lower than that of re-manufactured equipment, and the increase in
costs of sales for repair services discussed above.

Operating, Selling, General and Administrative Expenses.  Operating, selling,
general and administrative expenses include all personnel costs, including
fringe benefits, insurance and taxes, occupancy, transportation (other than
freight-in), communication and professional services, among other less
significant accounts.  Operating, selling, general and administrative expenses
decreased by $61,000 in the first quarter of fiscal 2005, to $1.51 million from
$1.57 million for the same period in 2004, a decrease of 3.9%.  The decrease in
operating, selling, general and administrative expenses was primarily due to
decreases in maintenance and utilities expenditures during the three months
ended December 31, 2004.

Income from Operations.   Income from operations rose $255,000, or 11.4%, to
$2.49 million for the first quarter of fiscal 2005 from $2.23 million for the
same period last year.  This increase was primarily due to increases in sales
to the larger MSOs, partially offset by the increase in costs of sales in 2005.

Interest Expense.  Interest expense for the three months ended December 31,
2004 was $146,154 compared to $55,753 for the same period last year.  The
increase was primarily attributable to the increase in notes payable at
September 30, 2004.  The weighted average interest rate paid on our outstanding
borrowings increased to 5.3% for 2005 from 2.75% for 2004.

                                   15


Income Taxes.  The provision for income taxes for fiscal 2005 increased to
$828,000 from $785,000 in fiscal 2004.  This increase was primarily due to
higher pre-tax earnings in fiscal 2005.

Year Ended September 30, 2004, Compared to Year Ended September 30, 2003 (all
references to years are to fiscal years)

Net Sales.  Net sales climbed $13.7 million or 41.2% to $47.1 million for 2004
from $33.3 million for 2003. Sales of new and refurbished equipment increased
47.3% from $28.8 million in 2003 to $42.4 million for 2004, primarily due to
the positive results of our marketing initiatives and the strengthening of our
distributor relationships. Sales of new Scientific-Atlanta and Motorola
equipment increased substantially as we strengthened our strategic alliances
with these manufacturers. Repair service revenues increased by 2.7% from $4.5
million last year to $4.6 million this year. The increase in repair services
was due to the continued focus of being a leading repair service provider for
both warranty and non-warranty repairs.

Costs of Sales.  Costs of sales includes the costs of new and refurbished
equipment, on a weighted average cost basis, sold during the period, the
equipment costs used in repairs, and the related transportation costs. Costs of
sales this year were 61.2% of net sales compared to 57.2% last year. Costs of
sales for new and refurbished equipment increased to 65.2% of net sales for
2004 from 63.3% of net sales for 2003. This was primarily due to the higher
proportion in 2004 of sales of new equipment, which has margins lower than that
of refurbished equipment. Costs of sales for repair services increased to 24.6%
of net sales for 2004 from 19.9% of net sales for 2003. This increase was due
primarily to the high-end hybrid and fiber optic equipment being repaired,
which involves a higher relative cost of material.

Gross Profit.  Gross profit climbed $4.0 million, or 28.1%, to $18.3 million
for fiscal 2004 from $14.3 million for fiscal 2003. The gross margin percentage
was 38.8% for the current year, compared to 42.8% for last year. The percentage
decrease was primarily due to an increase in sales of new and surplus
equipment, which is accompanied by margins lower than that of re-manufactured
equipment or repairs.

Operating, Selling, General and Administrative Expenses.  Operating, selling,
general and administrative expenses include all personnel costs, including
fringe benefits, insurance and taxes, occupancy, transportation, communication
and professional services, among other less significant accounts.  Operating,
selling, general and administrative expenses increased by $693,000 for fiscal
2004 to $8.5 million from $7.8 million in 2003, an increase of 8.9%.  The
increase in operating, selling, general and administrative expenses was
primarily due to increases in salaries and wages and the incurrence of fees for
the Company's commencement of trading on the American Stock Exchange.

Income from Operations.  Income from operations increased $3.3 million, or
53.1%, to $9.5 million for 2004 from $6.2 million for 2003. This increase was
primarily due to increases in sales of new equipment to the larger MSOs,
partially offset by the lower margins received and the increase in our
operating, selling, general and administrative expenses.

Interest Expense.  Interest expense for fiscal 2004 was $158,000 compared to
$217,000 in fiscal 2003. The decrease was primarily attributable to a lower
average interest rate on our line of credit and the lower average balances
outstanding on this line during 2004. The weighted average interest rate paid
on the line of credit decreased to 2.85% for 2004 from 2.98% for 2003.

                                   16

Income Taxes.  The provision for income taxes for fiscal 2004 increased to $3.5
million from $1.5 million in fiscal 2003. The increase was primarily due to
higher pre-tax earnings in fiscal 2004 and a reduction in fiscal 2003 of the
Company's allowance against deferred tax assets due to favorable tax
developments during that period. For a more complete discussion of income
taxes, please see "Note 4 - Income Taxes" in the notes to the consolidated
financial statements.

Year Ended September 30, 2003, Compared to Year Ended September 30, 2002 (all
references to years are to fiscal years)

Net Sales.  Net sales climbed $7.9 million or 31.2% to $33.3 million for 2003
from $25.4 million for 2002. Sales of new and refurbished equipment increased
33.9% from $21.5 million for 2002 to $28.8 million for 2003 as we strengthened
our role as a Master Distributor for several of Scientific-Atlanta's legacy
products and increased sales of Motorola products.  Our focus on increasing
repair revenue resulted in a 15.8% increase in those revenues, from $3.9
million for 2002 to $4.5 million for 2003. The increase in repair services was
due to the continued focus of being a leading repair service provider and the
expansion of our repairs sales to our Atlanta operations which began in June of
2002.

Costs of Sales.  Costs of sales includes the costs of new and refurbished
equipment, on a weighted average cost basis, sold during the period, the
equipment costs used in repairs, and the related transportation costs. Costs of
sales for 2003 were 57.2% of net sales compared to 56.6% for 2002. Costs of
sales for new and refurbished equipment decreased slightly to 63.3% of net
sales for 2003 from 63.8% of net sales for 2002. This was primarily due to the
write-down of inventory in 2002 of $1.4 million, partially offset by the
allowance for obsolete inventory recorded in 2003 of $447,000. Costs of sales
for repair services increased to 19.9% of net sales for 2003 from 16.9% of net
sales for 2002. This increase was due primarily to the increase in our repairs
on more high-end hybrid and fiber optic equipment, which involve a higher
relative cost of material.

Operating, Selling, General and Administrative Expenses.  Operating, selling,
general and administrative expenses includes all personnel costs, including
fringe benefits, insurance and taxes, occupancy, transportation (other than
freight-in), communication and professional services, among other less
significant accounts. Operating, selling, general and administrative expenses
increased $629,000 or 8.8% in 2003 over the previous year. Most of this
increase was directly attributable to the commencement of operations of Tulsat-
Atlanta in June 2002, coupled with an expanding sales force and other added
expenses incurred to meet the marketing initiatives described previously.

Income from Operations.  Income from operations increased 74.6% to $6.2 million
for 2003 from $3.5 million for 2002. This increase was primarily due to the
increase in net sales and the inventory write-down in 2002, partially offset by
the charge in 2003 to reduce inventory for obsolete equipment and the increase
in our operating, selling, general and administrative expenses.

Interest Expense.  Interest expense for fiscal 2003 was $217,000 compared to
$245,000 in fiscal 2002. The decrease was primarily attributable to a lower
average interest rate on our line of credit, partially offset by higher average
balances outstanding on this line during 2003. The weighted average interest
rate paid on the line of credit decreased to 2.98% for 2003 from 3.67% for
2002.

Income Taxes.  The provision for income taxes for fiscal 2003 increased to $1.5
million from $1.1 million in fiscal 2002. The increase was primarily due to
higher pre-tax earnings, partially offset by a favorable impact from changes in
the deferred tax valuation allowance. For a more complete discussion of income
taxes, please see "Note 4 - Income Taxes" in the notes to the consolidated
financial statements.

Critical Accounting Policies

     Note 1 to the Consolidated Financial Statements in this prospectus
includes a summary of the significant accounting policies or methods used in
the preparation of our Consolidated Financial Statements. Some of those
significant accounting policies or methods require us to make estimates and
assumptions that affect the amounts reported by us. We believe the following
items require the most significant judgments and often involve complex
estimates.

    General 
    -------
    
    The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting periods. We base our estimates and judgments on historical
experience, current market conditions, and various other factors we believe to
be reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Actual results may differ from these
estimates under different assumptions or conditions. The most significant
estimates and assumptions relate to the carrying value of our inventory and, to
a lesser extent, the adequacy of our allowance for doubtful accounts.

                                  17

        
     Inventory Valuation

     Inventory consists of new and used electronic components for the cable
television industry.  Inventory is stated at the lower of cost or market.
Market is defined principally as net realizable value.  Cost is determined
using the weighted average method.
       
     We market our products primarily to MSOs and other users of cable
television equipment who are seeking products of which manufacturers have
discontinued production, or are seeking shipment on a same-day basis.  Our
position in the industry requires us to carry large inventory quantities
relative to quarterly sales, but also allows us to realize high overall gross
profit margins on our sales.   Carrying these large inventories represents our
largest risk.  For individual inventory items, we may carry inventory
quantities that are excessive relative to market potential, or we may not be
able to recover our acquisition costs for sales we are able to make in a
reasonable period.  Over the past two years, our investment in inventory has
shifted to become predominantly new products purchased from manufacturers and
"surplus-new" products, which are unused products purchased from other
distributors or MSOs.
       
     In order to address the risks associated with our investment in inventory,
we regularly review inventory quantities on hand and reduce the carrying value
by recording a provision for excess and obsolete inventory based primarily on
inventory aging and forecasts of product demand and pricing.  The broadband
industry is characterized by changing customer demands and changes in
technology that could result in significant increases or decreases of inventory
pricing or increases in excess or obsolete quantities on hand.  Our estimates
of future product demand may prove to be inaccurate; in which case the
provision required for excess and obsolete inventory may have been understated
or overstated.  Although every effort is made to ensure the accuracy of
internal forecasting, any significant changes in demand or prices could have a
significant impact on the carrying value of our inventory and reported
operating results.  Demand for some of the items in our inventory has been
impacted by recent economic conditions present in the cable industry.  As of
September 30, 2004, we have reduced inventories by recording an allowance for
excess and obsolete inventories totaling $1,093,000.  No addition to this
allowance was recorded during the three months ended December 31, 2004.  An
allowance of $201,000 was recorded during the three months ended December 31,
2003.
       
     Accounts Receivable Valuation
     -----------------------------

     Management judgments and estimates are made in connection with
establishing the allowance for doubtful accounts. Specifically, we analyze the
aging of accounts receivable balances, historical bad debts, customer
concentrations, customer creditworthiness, current economic trends and changes
in our customer payment terms. Significant changes in customer concentration or
payment terms, deterioration of customer creditworthiness, or weakening in
economic trends could have a significant impact on the collectibility of
receivables and our operating results. If the financial condition of our
customers were to deteriorate, resulting in an impairment of their ability to
make payments, additional allowances may be required.  At December 31, 2004,
accounts receivable, net of allowance for doubtful accounts of $68,000,
amounted to $5.1 million.

Liquidity and Capital Resources

     We have a line of credit with the Bank of Oklahoma under which we are
authorized to borrow up to $7.0 million at a borrowing rate based on the
prevailing 30-day LIBOR rate plus 2.0% (4.4% at December 31, 2004.)  This line
of credit will provide the lesser of $7.0 million or the sum of 80% of
qualified accounts receivable and 50% of qualified inventory in a revolving
line of credit for working capital purposes.  The line of credit is
collateralized by inventory, accounts receivable, equipment and fixtures, and
general intangibles and had an outstanding balance at December 31, 2004, of
$2.4 million, due September 30, 2005.  We intend to renew the agreement at the
maturity date under similar terms.
	
     An $8 million amortizing term note with Bank of Oklahoma was obtained to
finance the redemption of the outstanding shares of our Series A Convertible
Preferred Stock at September 30, 2004.  The outstanding balance on this note
was $7.7 million at December 31, 2004.  The note is due on September 30, 2009,
with monthly principal payments of $100,000 plus accrued interest, and the note
bears interest at the prevailing 30-day LIBOR rate plus 2.50%.  An interest
rate swap was entered into simultaneously with the note on September 30, 2004,
which fixed the interest rate at 6.13%.  Notes payable secured by real estate
of $375,270 are due in monthly payments through 2013 with interest at 5.5%
through 2008, converting thereafter to prime minus .25%.

     We finance our operations primarily through internally generated funds
and the bank line of credit.  Monthly payments of principal for notes payable
and loans used to purchase buildings total $1.2 million in the next 12 months.
 We expect to fund these payments through cash flows from operations.

              QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Our exposure to market rate risk for changes in interest rates relates
primarily to our revolving line of credit.  The interest rates under the line
of credit fluctuate with the LIBOR rate.  At December 31, 2004, the outstanding
balances subject to variable interest rate fluctuations totaled $2.4 million.
Future changes in interest rates could cause our borrowing costs to increase
or decrease.

     We maintain no cash equivalents.  However, we entered into an interest
rate swap on September 30, 2004, in an amount equivalent to the $8 million
notes payable in order to minimize interest rate risk.  Although the note bears
interest at the prevailing 30-day LIBOR rate plus 2.50%, the swap effectively
fixed the interest rate at 6.13%.  The fair value of this derivative, $16,514
at December 31, 2004, will increase or decrease opposite any future changes in
interest rates. All sales and purchases are denominated in U.S. dollars.

             CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

30, 1999, the real estate and improvements comprising the headquarters and a
substantial portion of the other office and warehouse space of TULSAT
Corporation for a price of $1,286,000.  The price represents the appraised
value of the property less the sales commission and other sales expenses that
would have been incurred by TULSAT Corporation if it had sold the property to
a third party in an arm's-length transaction.  TULSAT Corporation entered into
a five-year lease commencing October 1, 1999 with Chymiak Investments, L.L.C.
covering the property.  This lease was renewed on October 1, 2004 and will
expire on September 30, 2008.

Texas, borrowed $150,000 on June 26, 2001 from Chymiak Investments, L.L.C for
the purchase of a building consisting of office and warehouse space at the
location in Texas.  The note was payable at 7.5% over 10 years.  Total interest
paid in fiscal 2004, 2003 and 2002 was $4,898, $9,869 and $10,694,

     In fiscal 2002, ADDvantage Technologies Group of Missouri completed
additions at its location in Missouri and financed $342,000 from Chymiak

2004, 2003 and 2002 was $11,694, $23,371 and $21,657, respectively.  The note
was repaid in April 2004.

     Chymiak Investments Inc., which is owned by Kenneth A. Chymiak and his
wife, Susan C. Chymiak, owns three other properties leased to TULSAT
Corporation for five-year terms (all ending in 2008).

     We had outstanding, unsecured shareholder loans of $800,000 at September
30, 2003.  Of this amount, $650,000 was payable to revocable trusts for the
benefit of Kenneth A. Chymiak and his wife and $150,000 was payable to David E.
Chymiak.  The interest rate on the notes was 1.25% below the Chase Manhattan
Bank Prime, which was the same rate as our bank line of credit. The total
interest paid on the notes in fiscal 2004, 2003 and 2002 was $19,134, $30,323
and $47,352, respectively.  These notes were repaid in August and September
2004.

     We lease various properties primarily from two companies owned by David E.
Chymiak and Kenneth A. Chymiak as discussed above.  Future minimum lease
payments under these leases are as follows:

                        2005                             $   480,240

      REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


The Stockholders of
ADDvantage Technologies Group, Inc.

We have audited the accompanying consolidated balance sheets of ADDvantage
Technologies Group, Inc. and subsidiaries (the "Company") as of September 30,
2004 and 2003, and the related consolidated statements of income, changes in
stockholders' equity and cash flows for each of the three years in the period
ended September 30, 2004. These financial statements are the responsibility of
our management.  Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States).  Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements.  An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation.  We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
ADDvantage Technologies Group, Inc. and subsidiaries as of September 30, 2004
and 2003, and the consolidated results of their operations and their cash flows
for each of the three years in the period ended September 30, 2004, in
conformity with accounting principles generally accepted in the United States
of America.

Our audits were conducted in accordance with the standards of the Public
Company Accounting Oversight Board (United States) and were made for the
purpose of forming an opinion on the basic consolidated financial statements
taken as a whole.  The consolidated supplemental schedule II is presented for
purposes of complying with the Securities and Exchange Commission's rules and
are not a part of the basic consolidated financial statements.  This schedule
has been subjected to the auditing procedures applied in our audits of the
basic consolidated financial statements and, in our opinion, are fairly stated
in all material respects in relation to the basic consolidated financial
statements taken as a whole.

As discussed in Note 1 to the consolidated financial statements, in 2003, we
changed our method of accounting for goodwill as a result of adopting the
provisions of Statement of Financial Accounting Standards No. 142 "Goodwill and
Other Intangible Assets."

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                  Years ended September 30, 2004, 2003 and 2002


Note 1 - Summary of Significant Accounting Policies

Description of business

ADDvantage Technologies Group, Inc. and its subsidiaries (the "Company")
sell new, surplus, and re-manufactured cable television equipment throughout
North America, Latin America and South America in addition to being a repair
center for various cable companies. The Company operates in one business
segment.

Principles of consolidation

The consolidated financial statements include the accounts of ADDvantage
Technologies Group, Inc. and its subsidiaries: Tulsat Corporation, NCS
Industries, Inc., Tulsat Atlanta LLC, ADDvantage Technologies Group of Missouri,
Inc. (dba "ComTech Services"), ADDvantage Technologies Group of Nebraska, Inc.
(dba "Lee Enterprise") and ADDvantage Technologies Group of Texas, Inc. (dba
"Tulsat Texas"). All significant intercompany balances and transactions have
been eliminated in consolidation.

Accounts receivable

Trade receivables are carried at original invoice amount less an estimate
made for doubtful receivables based on a review of all outstanding amounts on a
monthly basis. Management determines the allowance for doubtful accounts by
regularly evaluating individual customer receivables and considering a
customer's financial condition, credit history, and current economic conditions.
Trade receivables are written-off when deemed uncollectible. Recoveries of trade
receivables previously written-off are recorded when received.

Inventory valuation

Inventory consists of new and used electronic components for the cable
television industry. Inventory is stated at the lower of cost or market. Market
is defined principally as net realizable value. Cost is determined using the
weighted average method.

Property and equipment

Property and equipment consists of office equipment, other equipment, and
buildings, with estimated useful lives of 5 years, 10 years, and 40 years,
respectively. Depreciation is provided using straight line and accelerated
methods over the estimated useful lives of the related assets. Leasehold
improvements are amortized over the remainder of the lease agreement. Repairs
and maintenance are expensed as incurred, whereas major improvements are
capitalized. Depreciation and amortization expense was $277,352, $257,821 and
$157,267 for the years ended September 30, 2004, 2003 and 2002, respectively.

                                  F-8                                     

Income taxes

The Company provides for income taxes in accordance with the liability
method of accounting pursuant to Statement of Financial Accounting Standards
("SFAS") No. 109, "Accounting for Income Taxes." Under this method, deferred tax
assets and liabilities are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases, and tax
carryforward amounts. Management provides a valuation allowance against deferred
tax assets for amounts which are not considered "more likely than not" to be
realized.

Revenue recognition

Our principal sources of revenues are from sales of new, remanufactured or
used equipment, and repair services. The Company recognizes revenue for product
sales when title transfers, the risks and rewards of ownership have been
transferred to the customer, the fee is fixed and determinable, and the
collection of the related receivable is probable which is generally at the time
of shipment. The stated shipping terms are FOB shipping point per our sales
agreements with customers. Accruals are established for expected returns based
on historical activity. Revenue for services is recognized when the repair is
completed and the product is shipped back to the customer.

Derivatives

     SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities", as amended, requires that all derivatives, whether designated in
hedging relationships or not, be recorded on the balance sheet at fair value. If
the derivative is designated as a fair value hedge, the changes in the fair
value of the derivative and of the hedged item attributable to the hedged risk
are recognized in earnings. If the derivative is designated as a cash flow
hedge, the effective portions of the changes in the fair value of the derivative
are recorded in Other Comprehensive Income and are recognized in the income
statement when the hedged item affects earnings. Ineffective portions of changes
in the fair value of cash flow hedges are recognized in other income (expense).

     Our objective of holding derivatives is to minimize the risks of interest
rate fluctuation by using the most effective methods to eliminate or reduce the
impact of this exposure. The Company has designated its interest rate swap as a
hedge for the underlying note payable. Interest expense on the note is adjusted
to include the payment made or received under the interest rate swap agreement.

Freight

Amounts billed to customers for shipping and handling represent revenues
earned and are included in Net Sales Income and Net Service Income in the
accompanying Consolidated Statements of Income. Actual costs for shipping and
handling of these sales is included in Costs of Sales.

                                   F-9

Advertising costs

Advertising costs are expensed as incurred. Advertising expense was
$265,112, $229,534 and $224,468 for the years ended September 30, 2004, 2003 and
2002 respectively.

Management estimates

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

Any significant, unanticipated changes in product demand, technological
developments or continued economic trends affecting the cable industry could
have a significant impact on the value of our inventory and operating results.

Concentrations of credit risk

Financial instruments that potentially subject the Company to concentration
of credit risk consist principally of trade receivables. Concentrations of
credit risk with respect to trade receivables are limited because a large number
of geographically diverse customers make up our customer base, thus spreading
the trade credit risk. The Company controls credit risk through credit
approvals, credit limits, and monitoring procedures. The Company performs
in-depth credit evaluations for all new customers but does not require
collateral to support customer receivables. In 2004, we purchased approximately
39% of our inventory from Scientific-Atlanta and approximately 14% of our
inventory from Motorola. The concentration of suppliers of our inventory
subjects us to risk.

Goodwill

     In July, 2001, the Financial Accounting Standards Board ("FASB") issued
Statements of Financial Accounting Standards No. 142, "Goodwill and Other
Intangible Assets" (SFAS 142). SFAS 142 addresses financial accounting and
reporting for acquired goodwill and other intangible assets. SFAS 142 requires,
among other things, that companies no longer amortize goodwill, but instead test
goodwill for impairment at least annually. SFAS 142 was adopted by the Company
on October 1, 2002, the date of the annual impairment review. The Company
completed its transitional impairment testing of goodwill, which indicated that
goodwill was not impaired as of October 1, 2002. Therefore, the adoption of this
pronouncement had no impact on the Company's carrying value of its goodwill.
Annual impairment testing indicates that goodwill is not impaired as of
September 30, 2004. If SFAS 142 had been adopted in 2002, the Company's earnings
would have been improved because of reduced amortization, as described below:

Employee stock-based awards

Employee stock-based awards are accounted for using the intrinsic value
method prescribed in Accounting Principles Board Opinion ("APB") No. 25,
"Accounting for Stock Issued to Employees" and related interpretations. Under
APB No. 25, compensation expense is based on the difference, if any, on the date
of grant between the fair value of the Company's stock and the exercise price.
The Company accounts for stock issued to non-employees in accordance with the
provisions of SFAS No. 123, "Accounting for Stock-Based Compensation."

SFAS No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123")
provides an alternative method of determining compensation cost for employee
stock options, which alternative method may be adopted at the option of the
Company. Had compensation cost been determined consistent with SFAS 123, the
Company's net income would not have changed significantly.

Earnings per share

Basic earnings per share are based on the sum of the average number of
common shares outstanding and issuable restricted and deferred shares. Diluted
earnings per share include any dilutive effect of stock options, restricted
stock and convertible preferred stock.

Fair value of financial instruments

The carrying amounts of accounts receivable and accounts payable
approximate fair value due to their short maturities. The carrying value of the
Company's line of credit approximates fair value since the interest rate
fluctuates periodically based on the prime rate. Terms of the stockholder loans
are similar to the bank loan. Management believes that the carrying value of the
Company's borrowings approximate fair value based on credit terms currently
available for similar debt.

                                    F-10

Impact of recently issued accounting standards

In January 2003, the FASB issued FASB Interpretation No. 46 (FIN 46),
"Consolidation of Variable Interest Entities," and a revised interpretation of
FIN 46 (FIN 46R) in December 2003. FIN 46 requires certain variable interest
entities to be consolidated by the primary beneficiary of the entity if the
equity investors in the entity do not have the characteristics of a controlling
financial interest or do not have sufficient equity at risk for the entity to
finance its activities without additional subordinated financial support from
other parties. The provisions of FIN 46 were effective immediately for all
arrangements entered into after January 31, 2003. We have not invested in any
entities that we believe are variable interest entities for which we are the
primary beneficiary. The adoption of FIN 46 and 46R had no impact on our
financial position, results of operations or cash flows.

     In November 2004, the FASB issued SFAS No. 151, "Inventory Costs", which
revised ARB No. 43, relating to inventory costs. This revision is to clarify the
accounting for abnormal amounts of idle facility expense, freight, handling
costs and wasted material (spoilage). This Statement requires that these items
be recognized as a current period charge regardless of whether they meet the
criterion specified in ARB 43. In addition, this Statement requires the
allocation of fixed production overheads to the costs of conversion be based on
normal capacity of the production facilities. SFAS 151 is effective for
inventory costs incurred during fiscal years beginning after June 15, 2005. We
believe that the adoption of this standard will have no material impact on our
financial position and results of operations.

Reclassifications

Certain reclassifications have been made to the 2003 and 2002 financial
statements to conform to the 2004 presentation.

New inventory includes products purchased from the manufacturers plus
"surplus-new" which is unused products purchased from other distributors or
multiple system operators. Used inventory includes factory remanufactured,
Company remanufactured and used products.

We regularly review inventory quantities on hand and a departure from cost
is required when the loss of usefulness of an item or other factors, such as
obsolete and excess inventories, indicate that cost will not be recovered when
an item is sold. Demand for some of the items in our inventory has been impacted
by recent economic conditions present in the cable industry. The Company
recorded a charge to allow for obsolete inventory at September 30, 2004,
increasing the cost of sales by $645,900. We recorded a charge to allow for
obsolete inventory at September 30, 2003, increasing the cost of sales by
$447,100. We wrote certain items in inventory down to their estimated market
values at September 30, 2002, increasing the cost of sales by $1,442,938.

Note 3 - Line of Credit, Stockholder Notes, and Notes Payable

At September 30, 2004, a $3,225,183 balance is outstanding under a $7.0
million line of credit due September 30, 2005, with interest payable monthly
based on the prevailing 30-day LIBOR rate plus 2.0% (3.84% at September 30,
2004). Borrowings under the line of credit are limited to the lesser of $7.0
million or the sum of 80% of qualified accounts receivable and 50% of qualified
inventory for working capital purposes. Among other financial covenants, the
line of credit agreement provides that the Company's net worth must be greater
than $15.0 million plus 50% of annual net income (with no deduction for net
losses), determined quarterly. The line of credit is collateralized by
inventory, accounts receivable, equipment and fixtures, and general intangibles.

Cash receipts are applied from the Company's lockbox account directly
against the bank line of credit, and checks clearing the bank are funded from
the line of credit. The resulting overdraft balance, consisting of outstanding
checks, was $471,620 at September 30, 2004, and is included in the bank
revolving line of credit.

An $8 million amortizing term note with Bank of Oklahoma was obtained to
finance the redemption of the outstanding share of the Series A Convertible
Preferred Stock at September 30, 2004. The note is due on September 30, 2009,
with monthly principal payments of $100,000 plus accrued interest, and the note
bears interest at the prevailing 30-day LIBOR rate plus 2.50%. An interest rate
swap was entered into simultaneously with the note on September 30, 2004, which
fixed the interest rate at 6.13%. Upon entering into this interest rate swap,
the Company designated this derivative as a cash flow hedge by documenting our
risk management objective and strategy for undertaking the hedge along with
methods for assessing the swap's effectiveness. At September 30, 2004, the fair
market value of the interest rate swap approximated its carrying value of $0.
Notes payable secured by real estate of $384,381 are due in monthly payments
through 2013 with interest at 5.5% through 2008, converting thereafter to prime
minus .25%.

The aggregate maturities of notes payable and the line of credit for the
five years ending September 30, 2009 are as follows:

The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option pricing model with the following weighted-average
assumptions used for grants in 2004: risk-free interest rates of 2.0%; expected
dividend yield of 0.0%; expected lives of 6 years; and estimated volatility of
142%.

The Series B Preferred Stock (the "Preferred Stock") has priority over the
Company's common stock with respect to the payment of dividends and the
distribution of assets. Cash dividends on the Preferred Stock shall be payable
quarterly when and as declared by the Board of Directors. Interest accrues on
unpaid dividends at the rate of 7% per annum. No dividends may be paid on any
class of stock ranking junior to the Preferred Stock unless Preferred Stock
dividends have been paid. Liquidation preference is equal to the stated value
per share. The Preferred Stock is redeemable at any time at the option of the
Board of Directors at a redemption price equal to the stated value per share.
Holders of the Preferred Stock do not have any voting rights unless the Company
fails to pay dividends for four consecutive dividend payment dates.

Note 3 - Earnings per Share

Basic and diluted net earnings per share were computed in accordance with
Statement of Financial Accounting Standards No. 128, "Earnings Per Share."
Basic net earnings per share is computed by dividing net earnings available to
common shareholders (numerator) by the weighted average number of common shares
outstanding (denominator) during the period and excludes the dilutive effect of
stock options.  Diluted net earnings per share gives effect to all dilutive
potential common shares outstanding during a period.  In computing diluted net
earnings per share, the average stock price for the period is used in
determining the number of shares assumed to be reacquired under the treasury
stock method from the exercise of stock options.

Note 4 - Line of Credit, Stockholder Loans, and Notes Payable

At December 31, 2004, a $2,409,214 balance is outstanding under a $7.0 million
line of credit due September 30, 2005, with interest payable monthly based on
the prevailing 30-day LIBOR rate plus 2.0% (4.4% at December 31, 2004).
Borrowings under the line of credit are limited to the lesser of $7.0 million
or the sum of 80% of qualified accounts receivable and 50% of qualified
inventory for working capital purposes.  Among other financial covenants, the
line of credit agreement provides that the Company's net worth must be greater
than $15.0 million plus 50% of annual net income (with no deduction for net
losses), determined quarterly.  The line of credit is collateralized by
inventory, accounts receivable, equipment and fixtures, and general
intangibles.

Cash receipts are applied from the Company's lockbox account directly against
the bank line of credit, and checks clearing the bank are funded from the line
of credit.  The resulting overdraft balance, consisting of outstanding checks,
was $645,149 at December 31, 2004, and is included in the bank revolving line
of credit.

An $8 million amortizing term note with Bank of Oklahoma was obtained to
finance the redemption of the outstanding shares of the Series A Convertible
Preferred Stock at September 30, 2004.  The outstanding balance on this note
was $7.7 million at December 31, 2004.  The note is due on September 30, 2009,
with monthly principal payments of $100,000 plus accrued interest, and the note
bears interest at the prevailing 30-day LIBOR rate plus 2.50%.  An interest
rate swap was entered into simultaneously with the note on September 30, 2004,
which fixed the interest rate at 6.13%.  Upon entering into this interest rate
swap, the Company designated this derivative as a cash flow hedge by
documenting our risk management objective and strategy for undertaking the
hedge along with methods for assessing the swap's effectiveness.  At December
31, 2004, the fair market value of the interest rate swap approximated its
carrying value of $16,514.  Notes payable secured by real estate of $375,270
are due in monthly payments through 2013 with interest at 5.5% through 2008,
converting thereafter to prime minus .25%.

Item 14.  Indemnification of Directors and Officers.

     The registrant's Certificate of Incorporation, as amended ("Certificate of
Incorporation") and Bylaws provide that each person who was or is made a party
to, or is involved in, any action, suit or proceeding by reason of the fact
that he or she was a director, officer, employee or agent of the registrant (or
was serving at the request of the registrant as a director, officer, employee
or agent for another entity) will be indemnified and held harmless by the
registrant, to the fullest extent not prohibited by the laws of Oklahoma.

     Under Section 1031 of the Oklahoma General Corporation Act (the "OGCA"), a
corporation may indemnify a director, officer, employee or agent of the
corporation against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him or her if he
or she acted in good faith and in a manner he or she reasonably believed to be
in or not opposed to the best interests of the corporation and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his or
her conduct was unlawful.  In the case of an action brought by or in the right
of a corporation, the corporation may indemnify a director, officer, employee
or agent of the corporation against expenses (including attorneys' fees)
actually and reasonably incurred by him or her if he or she acted in good faith
and in a manner he or she reasonably believed to be in the best interests of
the corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless a court finds that, in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses as the court shall deem proper.

     The OGCA permits Oklahoma corporations to include in their certificates of
incorporation a provision eliminating or limiting director liability for
monetary damages arising from breaches of their fiduciary duty.  The
Certificate of Incorporation provides that to the maximum extent permitted by
law, a director of the registrant shall not be liable to the registrant or its
shareholders for monetary damages for breach of fiduciary duty as a director.
The only limitations imposed under the OGCA and the Certificate of
Incorporation are that a director's liability will not be limited:  (i) for
breaches of the director's duty of loyalty to the corporation or its
shareholders, (ii) for acts or omissions not in good faith or involving
intentional misconduct or known violations or law, (iii) for the payment of
unlawful dividends or unlawful stock purchases or redemptions, or (iv) for
transactions in which the director derived an improper personal benefit.

     The foregoing summaries are necessarily subject to the complete text of
the statutes, the Certificate of Incorporation and Bylaws referred to above and
are qualified in their entirety by reference thereto.
