So, this M12 I had repaired a couple years ago has the left 6V6 red plating.
After it warms up it starts getting voltage on the input grid pin 5.
replace tube and it's okay BUT- there seems to be a around 2v on pin 5 of both output tubes if you turn the tremolo intensity pot up.
With the Intensity down there's maybe .2v on the grids. Ground that line and there is zero volts on the grids.
With the tremolo swinging away, my meter reads DC voltage on the grids, but that is just the AC trem signal swing, right?
Not really DC voltage?
The phase inverter caps were replaced, pull either 6V6 and there is no voltage on either pin 5.
So where could this DC voltage be coming from, or am I crazy?
