Very good. What transformers did you use and what speakers in that 2x12?

Re: HAD Modded Princeton - Project
I drew the attached draft based on the layout provided. There are unmarked values for several components on the layout, especially in the power supply. Feel free to correct any errors you see and I can correct them as needed. A great sounding amp, and one hell of a Princeton!

Re: HAD Modded Princeton - Project
Here's an updated draft based on the Small Special PS and other suggestions. Thanks, Dave. Just seeing if I can figure this out properly.
Here's a question: since a Princeton uses a TMB tone stack (with a fixed 6K8 middle value), when I look at the HAD Modded Princeton Layout, are the Middle and Bass controls on the layout mislabeled? Shouldn't the Middle be where the Bass is listed and vice versa? The bass pot has its ground lug directly to the buss bar ground. Isn't that wrong? Shouldn't that be the middle pot?
This is how it's drawn in the layout. I don't see how this splits the mids from the bass.
This seems more right to me, but of course, I could be wrong. Which EQ is correct?
