Henry 3CX3000A7 RF generator / amplifier

This is a full multi-kW Henry RF Generator based on the 3CX3000A7 tube and including the power supply and ~100w exciter. The whole thing was
taken out of service as a RF plasma source at a research lab. It put out 13.52 MHz @ 2kW CW, and I believe it was operational when it was
tossed out. As far as I've explored it, the Amp is in a common zero-bias grounded grid configuration with a tuned input network and a Pi-L
output network. I haven't had the time to apply any power to this system or correctly test any of the parts, so everything will be as-is. I
have mapped most of the circuit by hand, and I have a list of changes that you'd have to do to make it work on the ham bands.

Here is a link to an imgur album of the amp with a ton of pics: https://imgur.com/a/nTTcT

Once converted, this amp could run AM QRO or more all day with no sweat...well except for the heat from the tube :)

I've been sitting on this gen / amp for nearly a year now waiting for time to convert it to the ham bands. Unfortunately I've only been
getting busier, so I think it's time to sell this beast. I don't really want to part it out. I'd also prefer local pickup but I could
potentially freight ship it if you pay (It'll be a lot of $ as it weighs a few hundred lbs) or even deliver if you're within 2 or 3 hours of
Tampa, FL. Also, I'm not really looking to trade for anything and I'd like to get between $2500 and $3000 for it but am willing to negotiate.
Email me or call / text me at (8one3) - 48two - 163zero if you're interested.

Thanks!
