Hi all!
I have a few questions about the old 813 tubes.
Just looking into them it seems like they are at least as
rugged as the 3-500Z.
What is the absolut maximum power these tubes can deliver?
What is the absolute maximum anode voltage?
I'm presently using two of them in a G-G homebrew amplifier,
working SSB, RTTY and some CW on 20m.
Power out is close to 1,2kW when driven with 120W.
The output power is increasing with drive all the way up to 120W.
Can I push them harder?
