Hangman,
Not a problem - wishing you the best with the emergency and hope the outcome was good.
I got the impression that circuit design was constantly changing at Ampeg, as I can find nothing in the literature on the -M version of the Reverberocket. I do like the fact that the -M set up for the easy-to-get and inexpensive 12A-type preamp tubes.
I will cease using the Piazza schematic as, even though neatly drawn, it was confusing. Thank you for updating the R12R schematic in the docs; I will refer to this from now on.
Lack of inverter tube plate voltage was a bit disconcerting. I'll check for voltage on other side of plate resistor and then look at point C in the power supply and report back. Thank you for the valuable guidance.
