Page 65 of Eimac's "Care and feeding of power grid tubes" shows a
selection guide for SSB service for which the 4CX250B is listed as being
capable of 348W "useful power output" in AB1 with a 3rd order distortion
product of -25dB (doesn't say whether its relative to carrier power or one
tone of two tones).
I suspect that this is in "ideal conditions", new tube, perfect matching on
input and output, correct anode and screen voltage, etc. etc. YMMV.
