One other thing to look at... the bypass caps on the cathode of the two triode halves of that 12AX7 in the vibrato/tremolo section. Use 25mfd/50VDC caps, as replacement.

Oh no! I feel like such an arse, and apparently I know nothing and can't even read a schematic. :oops:

The vibrato in the Pro Reverb wiggles the signal, and NOT the output tube bias. My apologies for being such a jerk! :oops:
