[Amps] Amp output power

[Jim Hargrave]

I homebrewed a pair of Eimac 4-400As GG in 1979 and it's still going
strong. 
I treat it gently since I don't have any spares.
It loads better on 10/15m than my Clipperton L, which which still
has original 572B's (x4) since 1982.
Treat'em right and they do well and last a long time.
