Thanks for the kind word Billy and Wilkie.
As the ‘prince of perfection’, I have since re-worked the final enclosure mock-up to include the two bass-boost toggles and a clipping diode selector. Instead of using the Roto-Tone PCB for diode selection, I’m considering the ‘DPDT Wiring Board’ to switch between Si & Ge diodes. I’m carefully choosing the diode combos for a higher total forward voltage drop to achieve bit less harsh clipping and less of a drastic volume change between the Si & Ge selection. And considering the space is getting tight around the OD pots and main PCB, I may forgo the ‘DPDT Wiring Board’ and just dead-bug the diodes to the DPDT toggle.
Anyway, here’s the intended final enclosure mockup . . . .
