By now you've figured out that I've been away from this stuff
for a year.  I was thinking of the stuff in the RCA tube manual
that shows how to set up the tube for a gain of 20, or 30, or 40, etc.
Fender preamp stages are typically set up for a gain of 40.
That would probably require some experimental tweeking of the
plate voltage to something other than the 45V figure you mentioned.
