Looking forward to seeing the evolving schematic, Kyle .
I'll try and find them. It started simple but now has a tone stack and all kinds of goodies lol. Thinking about splitting it up now because there isn't enough room on the chassis anymore. Plus, a stack with a separate power supply, preamp, and power sections would look neater

Yep it would look nice to have a preamp chassis amp chassis and power supply chassis. Plus that will reduce the chance of hum and unwanted feedback. When you do that be sure there are no ground loops. Everything must be grounded using the star ground method. Concerning your preamp chassis the only ground that should go to it is the power supply ground. The shielded cable used to connect the preamp to the amp should only have one side grounded to the chassis as the ground will be made through the power supply ground wire.
I have a Voice of Music amp with the driver tube in a box with the volume and input selector (tone controls and balance control not used) and I had to use 1/4" stereo jacks isolated from the metal chassis in order to eliminate a ground loop. Also the 1/4" stereo cables look neater than regular RCA cables do IMHO.
