Unit needs \"BYPASS/EQ\" push button switch replaced to restore full function . Besides this failure the unit is in very good cosmetic and functional condition . Not repairing this one because I had an identical backup . These are the cream of graphic equalizers , and cannot be topped for pure sound range adjustment and reproduction . Similar listings range from 199.00 up to 350.00 for fully functional units . This one can be had cheap for the price of a repair . This has been owned since purchased new in 1983 .
