Valve Identification
Is anyone able to ID this transmitting triode please? The only marking is 561 X. Very many thanks.

Re: Valve Identification
I have a similar triode. And a base for it! I'm wondering whether to make an audio amplifier, or a pantry transmitter.

Re: Valve Identification
That would make one hell of a 'Pantry-transmitter"...
