Right side works, left side not, unless volume is set way high, then
horrible staticy low volume. All output transistors removed & checked, all
good. Any ideas? Otherwise it's gonna get tossed, or maybe Ebayed for
parts.

Check the emitter resistors and that the speaker relay is working
correctly - it could have bad or damaged contacts, even just on the one
channel.

For that matter, check for any other possibly burned resistors. Could be
loss of voltage to the driver transistors on that channel.

It could be an FET in an interstage portion of the channel that's
breaking down. The older amplifiers that used FET's sometimes suffered
from this. We used to touch them with a soldering iron and that would
temporarily restore operation. Or perhaps an oxidized switch contact.
My 1974 Sansui receiver does this and I have to operate the tone cut
switch to get it working again. Disassembly is a nightmare and I've
been putting it off.
It might be something very simple but with all due respect this may be
beyond your abilities to find it. I sincerely wish you luck however if
as you say you cannot read a schematic then I would hold little hope
of your success. Lenny
