OK ... I looked at my Varian catalog and the 103 Amps was for the "J"
version of the 4CX5000/4CX1000. Still, the requirements for filament
power, air socket and air flow are a bit stiff for the amateur builder
(and no amateur commercial builder is using the 8171). What do you
think ... 9 KW with 7 KV on the anode and drive by a FT-1000 <G>?
