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.

I just bought a 4CX 5000A on a radio market here for a good price (180 Euro) including socket. SNIP Greetings.....Onno the 4CX5000A takes 10 Volts at 75 Amps, if I remember correctly. Dave F. Meant to say on the filiment, I had one at one time and mostly used as a paper weight. Dave F. |
It takes 5.0Volts at 90Amps! dave,,,,,Eddie

Onno...call them on the phone, their support is very good. They are located
in Quincy, Illinois. Broadcast Electronics 4100 North 24th Street Quincy ,Il. 62305 (217)224-9600 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 "Onno de Vries." wrote in message om... Hallo Eddy. Thanks for responding.
