 AMPHF - Henry 2K HF Amplifier For Sale  

Henry 2K HF Amplifier For Sale:
-
The Henry 2K is a monster HF amplifier,
covering 80 thru 10 meters.
-
It uses a pair of Eimac 3-500 Z tubes,
to easily produce full legal limit (1500
Watts) with about 100 watts drive.
-
It is a single stage amplifier designed
for SSB, CW, FSK and AM operation. It is
a very, very rugged, heavy duty amplifier,
with an extremely rugged power supply,
with a huge power transformer, choke input
filter, and oil filled filter caps. At over
150 pounds this amplifier is "built like a
tank".
-
Of course all of this is in a very nice floor
console, with the power supply in the bottom
portion, and the RF portion in the top.
-
This one works like it should. With full
power out of the exciter, it produces
1650 watts into a dummy load.
-
Cosmetically it is very close to perfect.
I can not find a scratch or defect on it.
-
Buy it with manual for $1200.
-
Since it is 150 lbs, it is obviously
pick up only, near Ocala, FL.
-
Thanks. 73,
