This is the design that the Hot Toddy morphed into, the GA-40 Lite based on the Gibson GA-40.
Longer write up here.
This is the schematic:
Here is a clip, just cranked up with a Les Paul.

“D” you come up with some really innovative designs ! The GA-40 power transformer a Hammond 261g6 has a center tapped secondary; is there a reason you didn’t use the center tap and went with a full wave bridge rectifier?? Jim D.
From the product information I got that it was 250v center tapped with 130ma and I was thinking I would just use a couple diodes and use the center tap. However each leg turned out to be about 135v (probably a bit above 125v because it has a 115v primary) so after the rectifier I was only getting about 185vdc.
I noticed that the documentation mentioned using it with the full wave bridge so I did that. I tapped off the center tap that got me in the ball park. Anyway, after some messing with the power rail and using a 150R sag resistor, I ended up with about 329 on the plates and 280 on the screens.
