** Probably c. 1.5kW PEP out with 200w drive. However, if more drive
is available, c. 2800w PEP should be possible (8kV at 600mA in x 60%
eff., tuning pulser tuneup).
-- The most VHF-stable design for a 450TH in g-g is to submount the
socket in order to move the grid lead close to the chassis.
- I have a socket if u need one.
-- If I were building such an amplifier, I would use one fan above the
chassis and one fan below the chassis to cool the envelope. Also, with a
tube this old, an initial gas check with a high-potential tester might be
a good idea.
