I'm having a problem dubing a bunch of 78s which skip a lot at that speed.

They seem to play through at 33.
Eq aside, if I record at 33, how many half-tones do I need to bump up the
sound file in the computer to get to 78.26 or thereabouts?


I'd recommend trying 45 rpm; the correction then is less than an octave.
Regardless, if your adjustment is by semitones, you will be significantly off.

78/45 = 1.733333...
78/33 = 2.363636... = 2 x 1.1818... = 1 octave plus ~3 semitones

If you can set fractions of a semitone, you should be able to set the multiple.
