Hi John, that's very interesting and I'm looking forward to seeing your designs."Unfortunately I'm a little afraid to try it on the big 813 amp, the 700V B+ is a little too close for comfort to the max rating of 1000V MOSFETs."
In a series MOSFET regulator, this shouldn't be a problem, should it? (unless you short the reg output accidentally to ground, that is!) I suppose if you were ue=sing a MOSFET as an error amp in a series rgulator, then it would be a concern although, even then, you could safeguard yourself by using a high voltage zener or VR tube in the source-to-ground circuit of the error amp. At least with MOSFETs you don't have heater-cathode voltage limits to worry about!
