RCA CTC...Something? poor HV output.

[Arcanine]

It actually had a 2AV2 in the socket. I still can get nothing from it on the tester with the correct filament voltage. It at least glows but does nothing.

I can get the needle to show something with the 3A3 and the other high voltage rectifiers, but this one shows nothing. Not even a little twitch.

I also don't think the socket has been modified at all to make a 2AV2 work.
