Hi all, I got this 432 KW amp from Bart, W9JJ. it's a beauty. The amp was built
in 2007 by K6KWQ. It uses a Russian GS35 triode. It has probably had 4 owners.
The 4th owner (me) hasn't used it at all as I have decided to go in a different
direction. It comes with a nice compact HV supply using a Peter Dahl
transformer that supplies a little over 2KV depending on 220VAC line voltage.
With that supply the rig shows around 9-10 db gain. As it sits it will do 900
watts with 100 watts drive and a stiff AC line. With a different P.S. and more
plate voltage the gain and power output will go up considerably. Many are
getting well over the legal limit out of a GS35 on 432. Below is a link to a
pic of the actual amp and supply that is still online: I can supply more pics
if you want. I have the coax relays for bypassing the amp too. A Relcomm D type
for the input and a Tohtsu CX800N for the output both 13.8v. . The Tohtsu is
good for about a KW and was used with the amp with existing supply.

I'd like $600 for the amp and $650 with the relays, $500 for the RF deck
without supply, but will consider reasonable offers. I will deliver or meet you
in New England for gas and toll money or can ship. Power supply weighs 50
pounds and RF deck weighs 35 pounds. I'm guessing shipping cost would be 50-100
bucks depending on what you want.
Happy to answer any questions! - bill, k1DY
