I looked at three of that model back in 1993 and '94 but for very minor problems like a loose RF input jack and "the remote doesn't work" (so, I put batteries in it).
Is the FCC ID# on the rear panel shown as ACJ927033A? If so, I can't cross that model to any others because I haven't seen any other models (of any brand) with that ID#. And, after 25 years the memory banks have run dry. Sorry...
