                       ADDVANTAGE TECHNOLOGIES GROUP, INC.
    ANNOUNCES RESTRUCTURING AND REDEMPTION OF CONVERTIBLE PREFERRED SHARES

     Broken Arrow, Oklahoma, September 30, 2004--ADDvantage Technologies Group,
Inc. (AMEX:AEY) announced today that it would redeem all of the outstanding
shares of its Series A 5% Cumulative Convertible Preferred Stock at its
aggregate stated value of $8,000,000.  The Company will finance the redemption
with a new credit agreement from its bank which includes a Revolving Credit
Commitment in the amount of $7,000,000 and a Term Loan Commitment in the amount
of $8,000,000.  The proceeds of the Term Loan will be used to redeem the Series
A Preferred Stock.  All of the outstanding shares of Series A Preferred Stock
are held beneficially by David Chymiak, Chairman of the Board and of the
Company, and Kenneth Chymiak, President and Chief Executive Officer of the
Company.

    Ken Chymiak, President and CEO of ADDvantage, said "Management and the
independent directors have determined that it would be advantageous for the
Company to redeem the outstanding shares of the Series A Preferred because the
dividends payable on the Series A Preferred Stock are not deductible for
federal and state income tax purposes and because the potential convertibility
features of the Series A Preferred Stock could be creating a market overhang of
common stock which could be restricting the desirability of the Company's
common stock as an investment by institutional and personal investors, thereby
adversely affecting the public market price of such shares.  By redeeming this
stock, the Company has eliminated the potential ownership dilution to the
public shareholders that could have occurred upon conversion of the preferred
stock."
