Re: Test equipment for valve radio repair
The most useful bit of kit I've got is a home made continuity tester based on an NE555 IC. Granted I've now got twenty-five years experience with it (crickey, that makes me feel old) but I know what things should sound like on it.
It's handy for far more than testing fuses, lamps and the like; it's even a good guide for capacitors. I tested a couple of high voltage electrolytics earlier today by a method similar to that detailed above and the results matched what I'd expected.
I'll try to find the circuit and post it.
