Thanks that helped, I suppose I could bolt the meter section of the item you provided details to and use the Popular Electronics circuit as that provides more voltage ranges than this one. I am looking at flexibility here and it is likely that I will not use the reformer part much if at all. Other than to check that any new electrolytics are good for service.
I have seen how to use them, often when you test a 400 volts Hunts capacitor or bumblebee type they are leaky even at 50 volts but well well below their working volts. The testers I have seen all use an electric eye tube in them which is very sensitive and form what I have read pretty indestructible compared to a meter. Now I wonder hmm.....oh well I could always wait for one to come up on line in auction.
But loathe to pay the prices that some of the CR Bridges and leakage testers go for, the Avo Bridge 1 (I think it is - the 1955 version) looks really good.
What is the best way to determine which is the inner and outer foil on modern capacitor (other than electrolytic)?
