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.

Hallo Eddy. Thank's for responding.
I allready did some seaching for this BE-5A transmitter and i found it
manny time's. The onely problem is that photo's,schematic's or
manuals are not there.
Atleast i cannot find them. I had some more reactions on my call in
the broadcast group. The collins 830F and the harris FM-25K are alsow
transmitters with the 4CX in the final but here it's the same. I
cannot find anny photo's or manuals. I thought (when i bought this
tube)it would be easy to get some info about it becourse it it a
,,famous,,tube.

Well i wil keep on seaching........buy the way,if You know where i can
find what i need,please let me know.

Regards. Onno.
