Hey Bajaman!
Thank you for your detailed explanation of the mods you do.
I will give it a shot this coming week. Customer dropped off his amp and its buzzing like crazy.
Someone already installed the 2200uf cap. I tested the ESR of all the caps and they are very low indicating good caps generally.
Any idea as to why some of these amps are buzzing and others not?
Also as to the heater voltage for V1 and V2: Does it matter that they are at ±10V and not the nominal 12V as indicated on most datasheets fro 12AX7's?
My first post here. Thank you!!
