CB amps...

If anyone is interested I have a couple of BIG 120V CB
linear amps. They use three 8950 tubes for about 800 watts p.e.p.

They would make a great basis for building a ham tube amplifier.

Everything is there, and they work, but are missing the 8950s.
Easy to adapt to some other tubes...

Built by "Man in a Cage" - or so I am told, he he. They look
quite professional. E-mail me off the list if you would like 
to have one.
