VINTAGE HUNTS CAPACITOR AND RESISTANCE ANALYSER CB3

[Mike Watterson]

The cheap Chinese R L C semiconductor testers are much easier to use than a bridge and are good enough for most people. They will give the wrong answer on a leaky or dried out electrolytic and won't see problems with leaky paper caps. A Low voltage current limited PSU for electrolytics and a several microamps limited 400V approx leakage tester for any other cap is needed before checking value. Mostly only some USA vintage silver mica will fail on value. All other caps typically fail on ESR/Dried out or leakage for electrolytic, or breakdown leakage on paper.
