To me, this is one of the best sounding amps I've heard! I really like the fact you can set it for an acoustic or use a bass guitar. Most amps I've seen are one or the other. I put the new pre tubes in and it silenced the noise, so down to tracking down a hum in the preamp section. It's not bad, and would pass like it is, but if I can diminish it, that would be great. Got a couple low voltage e caps on the supply line for a couple mosfets on the cathode of the 12AX7a's. May be the culprit. I'm posting a PDF schematic.
