The other day I was fussing about why testing Electrolytic caps is a pain... and it prompted questions about the testers I have, and how they work. So.. here you go.
I'm going to build the leakage tester seen in this youtube video. ( EO&N Cap Leakage Tester final build and testing ) Looks like a decent option, for not a lot of money.
It performs the same sort of high voltage test that the old school testers did. I like it. I managed to find an old school unit, so hopefully I can fix it.
I've also found that the old leakage method seems to be what the more experienced techs prefer. But hey, replacing old with new isn't a bad thing either. It all depends on the individual circuit demands. I'm trying to fix up an old scope atm myself, so I want to use this, plus esr and capacitance tests on the old caps inside it. My finished BOM/parts list on this leakage unit build are up to 80 ish euros/87 dollars. So not that cheap really. But it's probably the cheapest option for me. I've seen similar old oem units on ebay selling for 300 dollars plus, not including shipping, which is upwards of 100 dollars plus, too steep for me. Anyway, nice score on the oem unit, best of luck with it 😉 I'll check out the repair video 🙂 @@DeadKoby
