Kevin Gilmore Circlotron Output, Large Enclosure [high-slew] Electrostatic Amplifier
Hope you guys don't mind, but I'm taking the liberty to collect some info, links etc. here.
900V floating supplies
350V/us
the cole slew (couldn't resist) seems to be happening in bits and pieces in multiple threads on multiple forums and there are some implementation issues which seem to be worth discussing...namely fitting all of this somewhat daunting amplifier into one case.
I guess at some point Kevin decided to split the input and output stages-
output board
output schemat
I never had troubles with the HV900's, and haven't had any that blew, so the following is based on what I've found useful troubleshooting/checking the regular Golden Reference HV.
Often it can be helpful to work at lower voltages when trouble shooting. Paralleling the high resistor (is it 2x 450kohm in the HV900?) in the probe string to get the circuit in action at a lower output DC. If regulation doesn't work for some reason and things go bad it usually isn't really bad.
