Hello EG,

Crikey! Schems give me a headache at the best of times but that one made my eyes all funny. Lots of things I'm not used to (older Marshalls don't have any mute feature). Your theory is a possible, but there are still other things to consider and the valves are always a top suspect. The little ECC83s will give you zip output if one's failed and, because both EL34s work together in push-pull, one of those failing will knock your output, too.

Even if the mute is stuck in position, the valves will be fed power to keep them running. Do you have all of the filaments glowing when switched on?
