Thanks for the technical tips, very informative. I'm still learning my way around a schematic. I tested the voltage at the speakers and think I might have found a problem. Right channel was around 15-17mV but Left channel was 6.6 - 7 Volts (I didn't leave it on long enough to fully warm up). I tested with selector to AUX, no input, Volume at min, tone controls centered, no speakers connected and speaker switch on. But the numbers weren't too different when I connected speakers and tested again. The left channel is the side with the non-original output transistors, so could point toward a problem on that side?
I have a variac, but no DBT, though been meaning to build one. I ordered a manual, hopefully it has some info about idle current.
