That regulated PS would make a *serious* screen supply! That schem has some good info related to my questions, so thanks for posting it.
I'm aware of the heater-cathode voltage limitations, so I'd be using a small (6.3V@ .5 to 1A, for example) separate filament transformer for the regulator tube, properly referenced to a voltage that would keep the tube comfortable.
As I said, I'm not that concerned about having a rock-solid regulated voltage for the screen. I'm mostly interested in the voltage drop available, with the regulation as a bonus. I'd be running the screens at about 1/2 B+, so there's probably a very slim chance that the plates would ever get close to that low.
