Thanks Peter, I didn't have a suitable transformer, but have basically
ascertained they all work, with no variation in voltage drop, so
presumably all diodes are OK, using my variable PSU and a voltmeter.
Not as good as your way, but I am pretty confident they are all OK. As
you are in the UK, same as myself, what sort of money might I expect
to pay for a used, and usable hi-pot tester? Thanks
