I have toured their facility, they are a very nice group of people. The
factory is in a very quaint rural setting in Quincy. It's a "Stone-throw"
from the Harris Factory. A lot of the people that work at BE are ham radio
ops...I suspect you could get a hold of a BE-5A manual pretty easy.
Be VERY careful on the filiment voltage on the 4CX5000..it likes to be at
5.0 Volts. Don't let it sag below 4.8 Volts and over 5.25 Volts is not good
for it either. I have seen the BE-5A run at 72% eff..thats pretty
good.....Eddie

look at (and copy) the final circuit from a BE-5A (broadcast
electronics) FM
transmitter.It's very simple and very stable too. It likes about 200
watts
of drive from a IPA. Will run nicely with 5000 volts at about 1 amp on
the
plate. In the BE transmitter the tube sits in a cavity, with the plate
being
slide tuned. A coupling loop sits close to the tube....Eddie

My name is Onno de Vries and i'm living in the Netherland and
building
big amps is my hobby.
I just bought a 4CX 5000A on a radio market here for a good price
(180
Euro) including socket.

Greetings.....Onno


the 4CX5000A takes 10 Volts at 75 Amps, if I remember correctly.

Meant to say on the filiment, I had one at one time and
mostly used as a paper weight.
