Europa! ...er, Eureka! Icon_biggrin

I do believe I have localized the trouble...

I disconnected the input and output wires from the W15-079 control amp board and connected them together, not touching anything else, so there are no wires connected at the inputs or outputs of the control amp.

Yes, as expected, I had to turn the volume up, but it produced clean sound when connected in this fashion.

As the control amp is still "live" in that it is receiving voltage, I connected the signal tracer to the control amp's left channel output.

There it was...loud static...

I'm going to let it play for awhile to make sure the static does not reappear elsewhere, but at this point I believe I've found the problem - and I will have to rebuild the control amp board.

I think I will replace everything on this board, including resistors.
