This constant current source for high voltage loads was obtained from a 1967 General Electric documentation. The components are of the time, but allow equivalents.
This circuit is from 1968 General Electric documentation. It can certainly be adapted for any...
This tester from a 1960 magazine is only for capacitors with insulation voltages above 200 V (110...
Found in a 1991 publication this circuit can be assembled with more modern components. We can use...
