[Amps] 3CX1000A7

[Carl]

Ive been using that tube in my 2M amp for over 25 years and it sill puts out 
over 1500W and it was used when I got it. The Westinghouse branded spare 
(made by Eimac??) gets tossed in once a year for a couple of days.

They come up on the market very seldom and often very expensive as the 
primary user was 1000W VHF translator service on mountain tops in the 
boonies which are long obsolete.

It is also the lowest power Eimac rebuildable tube and its a shame that it 
didnt continue as a regular base socketed tube such as the wimpy 8877. A 
3CX1000A7 socket often sells for more than the tube.
