Great ideas - I'll add them in. I should have all the parts and be able to start building soon. Hopefully the next picture I post will be the of the actual amp!
The input pot still would be best located in front of the driver tube, instead of on one side.
I don't like switching the neutral instead of the hot mains lead. Hot>fuse>switch>tranny. Neutral>tranny. Switching the neutral will work but why be less safe?
Oops, good catch. I was drawing wires without thinking. I'll do it your way when I'm wiring everything.
A good order of wiring is:
Hot; Fuse; Switch; Primary; Primary; Neutral
I use 2 Fuses in series.
Example: 2 Amp Fast Blow, in series with 1 Amp Slow Blow
The amperage of the Fast Blow is determined based on the Inrush current at cold turn on, and also the inrush current with the amp hot, and switched off and on (Hot start). Flickering power can cause a Hot start inrush.
The amperage of the Slow Blow is determined based on the steady running current of the warmed up amplifier.

His Blue Glow YouTube videos for this amp and other tube stuff are quite excellent. Highly recommended for those who want/need to learn about tubes.
Does anybody have any objections to the positioning of this 220k ohm resistor (the one below the capacitor)? It's just mounted to the bottom of those lugs because it fits down there nicely. Any issue with using those holes, or should I try to stay on top? Thanks!
