Default Re: Test equipment for valve radio repair

I've come to see autoranging asmore of a detriment than an advantage. Before probing something, you should have a good idea of what should appear and of what faults could give, so you can set the right range manually before poking a probe in anywhere. THeadvantage then is that you get quick readings without waiting for the autorange to chug its way thrpugh several settings. If I'm working on a radio with 12v highest supply, a 20v DC range will be fine for just about everything.

For general looking around, my primary test instrument is a scope, not a meter. Scopes show voltage well enough for most work. They do it fast and they let you see all sorts of other clues.
