The Henry 3000D was designed for 300 Watts drive...the RF cabinet
as used in plasma areactors came with a solid state 300 Watt "driver".
There is a choice of two power supplies available depending on your
power source. One is single phase and delivers around 4800 VDC.
The other is 3 phase and has about the same ourput. Both have
taps for 208, 240 VAC.
With 300 watts drive the amp will easily deliver 3000 Watts output
with a good tube. Conversion to 20 meters amounts to retuning the
Pi-L , the input pi-net and adding an antenna switching system and
I do not think its a good choice for modification for more than
single band 20 meter operation.
