 3-500ZHFLinear Amplifier  
I am downsizing due to loss of eyesight. My Homebrew amp I built over yes must go. It originally used a 4-400, and still could, but I converted it to a 3-500Z. The tube is in very good shape. Tuned input.
It puts out 400 watts, with 600 watts input. 2000 volts at 300ma.
The power supply is newer. Hardly used.
80 -- 10 meters. Must have valid license to purchase.
I am an extra class since 1968, an EE professional engineer and an ex-ET in The Navy.
$240 Plus $100 packing and shipping. Two boxes.
I will ship tube in separate box for extra $25.
USPS Money Order, or Walmart Money order.

 Yaesu FL-7000 HF Amplifier For Sale  

Yaesu FL-7000 HF Amplifier For Sale:
-
The Yaesu FL-7000 is a completely solid
state HF amplifier covering 160 thru 10
meters, including the WARC bands. It
includes a very heavy duty power supply
in it, operating the final transistors
at 48 Volts DC.
-
It has two very large fans that provide
plenty of cooling and are relatively quiet.
-
Although it has an automatic antenna tuner
built in, it is recommended that the tuner
NOT be used.
-
It does operate full break in (QSK) on CW.
-
Cosmetically, it is very good. It does have
a couple very, very, very minor scratches
that you can find if you look just right.
-
Electrically, it produces full power, and
works as it should.
-
This amp is a brute, which means it is very
heavy -- 66 pounds before packing for shipping.
That means that pickup near Ocala, FL is very
desirable, but I can ship it if you are willing
to pay the price.
-
I would like $1200 for it.-
-
Thanks. 73,
Ken Simpson, W8EK
