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
