@superwarp1 posted:Are you nuts? I’ve repaired many tube type radios and if you don’t know what you are doing you could blow your scope (a specially if you don’t have a isolation transformer) and there’s hundreds of volts powering those tubes that could kill if you slip with the probe. I don’t recommend starting out with a tube radio.
Seriously Gary? Typical plate voltages run around 500 volts. The scope in question displays 10v/div with ten divisions is 100 volts. Use a 10x probe and you can measure 1000v. This is radio, no CRT anodes and flyback transformers. On a floating chassis use two channels added in minus mode to simulate a differential probe. You kids need to go back to school.
