V-rms obviously yields watts-RMS, and Volts-peak gives watts-peak.
Perhaps Reid Brandon? will chime in.? ?Right now, I can't fathom why Eimac would use peak cathode RF voltage? instead of RMD cathode voltage.
Because SSB is measured by it's peak: Peak Envelope Power. RMS only applies under continous carrier conditions.
