How does this schematic look to you (Harmony 430 content)

[prairie]

So I have an old Harmony 430 amp that I absolutely love, however, it's super difficult to work on, and I want to make improvements to the layout. And since I only ever use one channel, I figured I would have a go at recreating the schematic, but with just one channel (no tremolo or reverb).

I think I've got it right, but I'd love to hear your input. I plan on building this into a gutted Hammond A0-43 chassis and using its transformers.

Thank you in advance!
