FS: 3cx400A7: multiple 3cx400A7's used at various times in various amplifiers, all reasonably good. Will verify output in my Alpha 76A 3-hole before shipping. $400/ea. These are pretty hard to come by these days.

Have a eimac 4cx15000A that I’d like to trade for a
Peter Dahl plate transformer or nice HF transceiver .
Comes in original eimac box
Not the prettiest tube in the world but it’s a great pull.
Tube works and was a pull then used as a back up
Tube for the local tv/radio stations 21.5kw transmitter.
Bought this from a friend of mine that’s an engineer there
Possibly up for other trades but listed above is kind of what I need
Thanks

FS: 3cx800U7: Qty 2, Eimac 3cx800U7's $300/ ea
I always thought it might be an interesting project to make a socket to convert the U7 to the A7 pins as a replacement. Seems like a good way to get some replacement 3cx800A7's
I also have a 850 MHz cavity with a socket for the U7's

FS: 3cx400U7: multiple 3cx400U7 tubes for sale.
They have a bigger cooling fin than the 3cx400A7, but I always thought it would not be too hard to make an adapter to convert the coaxial tube to a pinned socket style for some of the older 3cx400A7 amps.
With the bigger cooling fin, probably a better deal too!
$150/ ea.
