Mostly, it seems that diodes in amplifiers are part of the bias stablization system of the output stage. I have a MARANTZ 2235 with failed bias stablization diodes and it sounds good but gets way to hot to touch in a short time.
So lets see what the TS can tell us about the diodes in their amplifier.
