potential Hoffman Princeton Reverb build
« on: January 30, 2022, 09:58:19 pm »
Looking at putting this together it looks cleaner and and more efficient than putting an ab763 together. I would however use a bridge rectifier and 6L6 tubes. I also want to see about adding a Mid pot as well. As long as i spec the PT for this are there any issues with my plan? How would i go about adding the Mid pot?

i don't have the schematic pulled up but my wild ass guess is that there is a resistor from the tone stack to ground (i wanna say something like 6k8ish?). replace that with a 25kB pot wired as a rheostat
