I just got a cool looking Tube tester.
I think it is a hickok 600 made in around '47 or 48.
It looks like it is new. Does anyone know anything about these ?
I just picked one of these up and I was wondering if it would work as a headphone amp/eq ?
I know that usually you cannot use rca line out jacks to drive headphones, but since this a car audio piece that instead of having 2v rms has (9.5 volts RMS/ 13 volts peak)...
