Ok thanks, I have IC300/301 out and the voltage at the base solder pads reads +/-32, TR313/314 don’t show E-C shorts, but I’m wary of them too.
Im not sure what killed the right channel on this, there was a goofy pair of wires badly soldered to the speaker terminals that looked short-y and these are notorious for having the bias voltage run away due to dirty pots. In fact the left channel bias ran away but it shut the amp down (tripped the main relay), I cleand that bias pot and the left channel is fine now
