If you are checking sections,you can put the Phase Inverter (PI) tubes in while it's on.Again I would like to ask,how much drift are you getting?
If it's 1ma or 2ma,it's well within tolerance.Most amps drift a bit but I think you may be making too much of it.

- I never even thought of the line voltage but that could very well be an issue if it varies. - Michael Samra 17:15:40 05/13/14 (9)

- Yeah, check the plate voltages when the bias reads differently - FenderLover 23:16:41 05/13/14 (7)
