Been trying to buy one on eBay, but I keep getting outbid. Guess others want

I'm guessing that the leakage current should be well below 1 ma for a healthy
condensor. Guess I'll have to throw together a 400v power supply (3 caps & 3
diodes should do, just triple 120vac from the wall) and test a few "known good"
condensers.
