Default Re: Test equipment for valve radio repair

Just about any fault on a radio can be diagnosed using a multimeter, either analogue or digital as preferred. DMMs can be bought exceedingly cheaply these days.

As for testing capacitors just forget it. Replace waxies and Hunts on sight. If you don't want to do that remember that the failure mode of these is to leak electrically and behave like resistors. This will result in incorrect voltage readings. For example low screen grid voltage or positive voltage on a control grid.

If you want more test gear invest in a signal generator. As for valve testers, scopes etc. forget them. They rarely need to be used.
