(1) Is the hum a constant level regardless of volume control setting... or does it vary with the VC setting?
Constant...
(2) Is the hum very loud or is it just a "background" type noise?
Not real load but annoying
(3) Is the hum a 60Hz tone or a 120 Hz tone?
Seems like 60hz..
Does hum go away with volume turned all the way down? NO Constant hum hum doesn't get loader with volume
Do both #41 tubes have B+ voltage an pin #2? YES 183 volts, 181 volts
Does pin #3 of each #41 tube have voltage? YES 185 volts, 171 volts
