Default Re: An old dinosaur bench top power supply - help needed

RJ - I performed the test. VOM negative to heatsink and VOM positive to negative leg of the gray vertical 100uf 50v cap. As I turned the pot the resistance would increase and decrease.

I did the same for the really big 25000MFD cap and the resistance would vary, but not in a linear fashion.
