As I no longer require help, I deleted my original post and replaced it with this.
This is a Scratch built Sonic Frontiers Power II from the schematic.
It has a current source for each of the driver valves and the negative bias supply. The driver section has regulated DC heaters.
This is the most complex design I have built to date. Thankfuly there was help and encuragment from the fine folks at the Parts Conexion. The design was originally their project.

Super impressive.
Do you know if Chris Johnson will share the schematic for diy enthusiasts? I guess I could contact him...

I can't speak for Mr. Johnson.

You can still get the transformer from PC.
