I'd also cut C8 down progressively.
Reduce C9 and C10 to 22nF.
But for what you want I'd redesign it to a single channel to add your gain stages.

Re: Two 20 watt amps in one chassis - layout/grounding
Best to build them as parallel pairs that share no components. Though a beefy supply well controlled should supply the power needed with little interaction. I would build them as mirror images of each other with the power supplies in the center of the chassis. The inputs on each end.

When she fired up the tubes the camera overload looked like she achieved fusion!
How about the fine pitch on those grid wires.

Re: $600 fuse, anyone?
So for A.C. I need two, in parallel, reversed, as they are directional.
If ever there was an industry that needs double blind testing, or the focus of the FTC, I think we have a winner.

Re: USA Source for a 5E3 Deluxe Chassis?
Yes it got the Sugi treatment. It's a one piece cab with a Weber A10Q and a C10Q. Here's the pedal compartment (7x6x7" deep). 20240405_170656.jpg Brilliant! Interesting choice of speaker combination.

Here's a stereo power amp I made as a final for a Magnatone clone. Each side is a single ended KT-88 driven by one side of a 12AU7. Stereo in, stereo out.

Re: USA Source for a 5E3 Deluxe Chassis?
It's far, far quieter. Filtering is better ground scheme is better, and the heaters are elevated. Having hand issues and upcoming surgery so progress has been slow but here's the cab in process. Sounds great with 2 10" speakers. 20231214_214706.jpg Thanks, very interesting info. Your cab, or is it ...

Re: USA Source for a 5E3 Deluxe Chassis?
It's a simple circuit to do PtP with a small Hammond box.
And easier with a turret board or card.

And be sure the bias voltage is at the pins before installing the power tubes.
