HI ALL..I have two linear amps for sale or trade. They were built by a
very dedicated ham in the
chicago area. one is a single band [10 t0 15 meters] using a 4CX1000
eimac tube, the power supply was separate as is the blower
for cooling.
The other is a 10 thru 80 meter rig using a pair of 3-400Z tubes, The
plate tank is that BIG B&W band switching PI-net assembly.
The plate tank switch is mechanically coupled to switched input
circuits, broad banded.
both linears were to be used with a common hv power supply which I have.
The plate tx is a "pole pig" of about 7200 acv center
tapped wit the solid state rectfiers mounted on its terminal board. From
what I can ascertain both linears were run at a conservative
kilowatt input. [or more, 3 kv at 900 ma!]. tubes are included.
any interest? contact me off reflectors? (847) 359 0941
