Slowly taking shape. Have to get back into the swing of things.
The signal section (preliminary design)
The raw DC supply for each channel's filaments. There will be seperate regulators behind this for the 1626 (12V) and 5842 (6V). It's a little over-engineered for the filaments of these tubes, but I might have some PCB's made for the future DHT amps, so I'm thinking ahead a bit and standardizing things (for how long that lasts).
Here is the regulator circuit for each filament I've added a soft-start section to slowly raise the voltage on the filament.
The B+ supplies for both tubes and channels.
