I'm going to try a different DVM also...

Somethings been nagging at me. When I used to check my output bias and DC balance every 6 months or so, I thought I always had to change from DC mA to DC volt settings along with switching one of the test leads. But at some point I recall getting zero reading set at DC mA for output so thought I was mistaken and both tests were to be done on the same DC volt setting, because only then would I get any readings.

But reading through past posts I think it should be DC mA for output and DC volt for balance. I know not to touch A.C. balance as I need a scope.

Either I've gone crazy or my DVM has. Hopefully the latter.

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)
