[Amps] care and feeding

[Carl]

Eimac made a series of cavity amps for the early cell phone industry using 
the 3CX400U7; 2 can be moved to 903.

Ive seen mention of others but havent looked for them.

There are a few commercial cavities using the RCA 7213 that will make 1296 
but they are hard to find.
