Hi Adrian

I sure hope no-one local to me buys that amp kit !

"2 x 4CX250B", "1kW" and "linear" don't go together. May be Ok to 600w, but
that's about it.

Good luck.

Hello all
 
*****Please reply off list*****
 
I have a stock of parts, suffcient to build a 1Kw 144MHz linear amplifier.
The chassis, case and power supply have already been build, leaving just the
component assembly on the RF deck to be completed. Included is a pair of
brand new, sealed 4CX250B's and  about 10 other 4CX250B's, lots of sockets,
spare parts, transformers etc etc.The chassis (RF Deck)  is made from Copper
Plate. PSU is capable of 2.1Kv or 2.8Kv at 1Amp. Also included is a metal
case with panel.
 
I also have full assembly instructions to build the RF Deck and test the
linear. PSU instructions & design docs also included. Just supply time &
solder.
 
If anyone is interested, please email me off list.
 
Location: Wales, UK
 
Best Regards
