Now $145 shipped lower 48:
Northern Radio Company N542 Kilowatt HF amp. It has six user set channels
> that cover 2-30 mhz. There is no PS. Designed to run with a supply that
will
> provide 4 KV. This amp is built like a tank. Sat in the previous owners
shed
> for 16 years, uncovered, but out of the weather. Needs lots of cleaning up
> on the top but the underside looks excellent. Uses a pair of Eimac SK-410
> air system sockets for the 3-500Zs (pair, not included). I do not have the
chimneys. The filament choke is missing. It uses a B&W model 800 plate
choke. There are six banks of 4500 volt air variables for the plate tuning
side and a bank of six much smaller spaced air variables for the loading
side. There are also numerous RF rated doorknobs, some 7.5 kv and some 5 kv.
There is no blower (but needs one).
>
> The tank coil is motorized so this is a very unique but probably difficult
> project amp. I do not have any documentation. My plan was to resurrect
back to life but it is too involved with this motorized tank set up and I
want to
> devote my time towards my vintage AM side of the shack. You could re-do
the tank. The large heavy duty ceramic switch is motorized.
>
> The front panel is a 19inch rack mount that is 16" tall. It has the
> following switches on the front:
>
> 1. filament and plate power on and off with indicators
> 2. channel 1-6 with indicators
> 3. local/remote with indicator
> 4. Po, Ik, Ip, Vp and the associated meter reads 0 to 1.0.
>
> Also has two fuse holders on the front panel.
