I'm trying to decided what to do about backup.

I was under the impression they were Electro Harmonix.

Do you mix brands of the same type of tube for different sounds? MM6 posted to tube location/function map. So many inter-relationships in ch1 & ch2 various gain stages all by the same tube.... Like amplifier voodoo :mrgreen: I do have the Jan GE 5751 or whatever that last number is, on the way for P1.

Run the 5751 in V1. It'll sound killer. 12AT7's work better for the PI as they produce more current than a 12AX7.
