Hum all the time, I have installed the upgrade output transformer, and the amp already had the presence control, twin tone stack mod.
Trouble is that I'm getting constant bad hum at idle. speaker, cables, tubes have been ruled out. the EQ can change the sound of it, but still sounds like a ground problem. any ideas ?
