Default Re: Test equipment for valve radio repair

Everybody above is correct, however the most often used item is a soldering iron and the king is a Weller. It is isolated(for those times you are working with power on) and the tip lasts. A good high impedance multimeter is essentual. The AVO 8 is tough and robust but I don't know if it has such a high impedance. Detuning when measuring is a pain and AGC circuits are easily affected. A good signal tracer is easy to build and will trace from the front end to the last AF stage easily. It will test the filaments(hum), oscillator(hiss) and if you can hear the signal in the IF stage then the fault could be the detector, ect.

Billy, I am so envious of you, the AS100d is a beatiful meter. Mine got stolen and I have never got over it.
