I have a bunch of 415A tubes. They are not listed on either of my tube testers. I am wondering how to test them, aside from heater continuity?

Also wondering where they are used, radios, etc?

Thank you. MC

The socket settings should be the same as the 6BH6 and 6BJ6 -- although those tubes don't seem to have internal shields connected to the cathode or screen grid. You should be able to check for shorts. For emissions test, you may have to experiment.

6AS6 is the commercial equivalent to 415A.
