BK Butler Tube Driver

Apparently it's tube week. Here's the Tube Driver made famous by David Gilmour. It uses a 12AX7 which is pushed by a dual opamp followed by a Fender-style tone stack. I kept the power section from John K's version of the Blue Tube. Fits easily in a 1590BB. Here's the schematic for reference.

Tube Works Blue Tube

Came across John K's vero of this circuit with a few mods (Mid pot, bipolar charge pump) and figured we needed a layout for it as well. Runs on 9-12v. Pots are all board mounted with the tube off board. Here's John's original layout.
