Tom,
$100 for a 1100w amplifier. Seems like a bargain to me. A guess
they were $5-10K brand new. Each has 16 MRF-150 (equivalents) in
them. 10w drive typically results in 1000-1100w. All that is need
is a 50v 40-50A PS. Those are common on ebay for $30.
Probably the TV station cannot give them away. Lots of companies
have such policies but can dispose them. Maybe if you could be at
the junk yard to pick them up, you could get better price (that will
be in Fairbanks, AK!).
Wish I had the funds for one. Wish I had $1800 to invest, I would
buy all and sell them for $800/ea. and do it easily.

Hmmm can't be too many scrap yards up there...
Seriously if he's going to scrap them why ask so much?

Fairbanks, AK. He is the chief engineer for a broadcasting company
up there, and is about to send 18 of these Harris amplifier modules
to the dump for scrap. They are part number 992-8969-011, and are
supposedly built to operate between 174-230 MHz without any
modifications. I don't know what the output would be at 2m with
the units as-is, or what it might take to tweak them to 2m. He
told me he thought each unit was tuned to put out around 500w,
which seems consistent with the Channel 2/6m Harris Platinum I amps
with which I have dealt. With the Channel 2 units, 10w drive
typically resulted in close to 1 kw output.

>> Thomas said he would prefer if someone would purchase all 18
units from him, but he would consider selling fewer units in the
interest of trying to prevent these valuable pieces from going to
the dump. If you agree to take all 18, the cost would be closer
to $100 each (plus bulk pallet shipping). If you only wanted a
one or two, the cost would be closer to $200 each plus UPS boxing
and shipping (which I generally found to be around $100 here). I am
sure you could run a pair of these in parallel (as I described on
my web page for the Channel 2 units), if you wanted to make sure
they would handle the legal limit, and 50 VDC power supplies are
very readily available:

amp, please contact Thomas directly ASAP at telephone number 907
322-1985. He advised me that they will be disposed of for scrap in
the next couple of days if no hams step forward to put them to use.
