No, I had not set the idle current as of yet. I decided to follow Mondial's advice.

All transistors are OK. All of the associated resistors, caps, and diodes appear to be OK.

So I put some DeoxIT on the power-speaker switch, reinstalled the transistors, and tried again with headphones only first.

It sounded fine.

Then I connected the speakers, only to the "remote" terminals instead of the "main" terminals.

I turned the thing on and to the "Remote" speaker position.

It sounded fine!

I turned it off, and changed the speakers over to the "Main" speaker terminals.

Turned it on again, only to the "Main" speaker position.

It sounded fine for less than a minute - then distortion returned first to the right channel, then to both.

I then turned it off and moved the speaker wires back to the "Remote" terminals.

Turned it on again....distortion.

So I think I have found the problem - the speaker selector switch.

Sometime this weekend, I think I'll run a couple wires direct to the main speaker terminals, bypassing the switch and testing my theory.
