QuoteI did check them
And what was the result? You tell us half the story :lmao:
Seriously, do as suggested above, with your meter on 20VAC check if you have 6.3VAC from pins 4+5 (they are usually united) to pin 9, and probably 12V DC from pins 4 to 5 in the first triodes.
Usual problem with *all* Bugeras is poor internal connectors , best is to pull them and solder wires straight to PCB pads.
