Default Re: Testing 807's.

It doesn't appease the pain of a bad valve, but it is somewhat cathartic to 'see' the actual fault (and then wonder how it could have passed any form of basic testing).

I'm about to use an insulation resistance tester on a batch of diodes - that may be an easy way to identify leakage, although using a high grid leak in a standard test jig should be able to detect abnormal grid conduction.
