Nope, not it. I would have found that quite easily. As I said in my first
post the main output stage is fine (you can inject a signal), the trouble
seems to be in the volume control section.
Maybe this thing just isn't worth bothering with.......

Check the speaker relay-s . Have the thing going and when it quits stick
a screwdriver across the relay contact pins on the bottom of the board
or ``whack`` the relay .
