This unit was done by us long ago. It does have our audio boards installed. However, this one has seen lots of "alien" things done to it after it left our shop. Obviously many of the big chassis mounted capacitors have been replaced. It is strange that they left the original larger brackets in place, holding nothing No point in that.
I can't tell what else has been changed. I can note that our original design did not run all that hot so probably there is something wrong with it.
I also can't tell if it would be economical to repair without putting it on our test bench and finding out hands on how badly it has been mangled.
I would advise avoiding it.

Frank Van Alstine
