I at least feel like I am not fumbling in total darkness, and I may even learn a thing or two.

Assuming a bad diode is the culprit, how best to find which one is bad? I can follow wires/traces to determine which bridge rectifier to test, so that should eliminate 4 out of the 8 diodes as suspects. I have a volt/ohm/ammeter, but not sure how to utilize it in this case. I did measure resistance across ea. diode (in place), in both directions, but none stood out as different, so I guess this is not a valid diagnostic. Could I ferret out the problem by powering up the amp to look for discrepancies in voltage drop across ea. diode?
