hello all, just built a blackface champ and am a little stumped. my B+ voltages are fine 355v and the cathode voltage on the 12ax7 is 2v but the 6v6 cathode resistor is dropping 83 volts. its supposed to be 19. the sound is bad very choppy almost like an intermitten solder joint. ruled those out though. the only thing not on the schem is im running diodes to rectify instead of a tube rec. if the B+ is ok could the solid state rec be providing more current than a tube one?

my only thought is to buy another output iron , tried a different 6v6 already
