[Amps] 4CX250B and data sheets in general.

I was thinking about that one too. I suspect that the spec was for use in portable SSB Military transceivers such as the PRC-47 where there is little concern with IMD products. Who cares in the jungle.  Same may be for the higher spec  for the 4CX250.

Following this thread, I pulled down my very-own 1955 Eimac catalog, because 
I happened to remember some specs relative to the 4-65A that I had wondered 
about from time to time.

This particular spec sheet, dated 1954, lists a "Max-signal useful power 
output" of 325 watts for a single tube, in linear SSB suppressed carrier 
service.

No distortion figures are mentioned.

BTW:  Colin, the hole was destroyed by decimation.
