I had one do this and it was a shorted output. It tested normal with your quick gate to source test with an ohm meter, but when I switched the probes in all configurations I found one that was shorted.


You have -18v at CR1 and CR2. Did you confirm they read ok as far as testing them with your meter?


Did you confirm what Perry asked for the good connection between their anode and the negative regulator?
