[Amps] Maximum RF output in practical application: 4-250A

[David G4FTC]

I've been following the thread and have an observation which I haven't seen 
anyone else mention.

Most professional linears (or up-market amateur units) have a rated rf 
output the same as the anode dissipation of the tube, i.e. a 1500 watt 
output amplifier will use tube(s) with an anode dissipation of ~1500 watts.

Of course more power out can be obtained from a given tube in low duty cycle 
modes, but for high duty cycle modes such as RTTY, JT65 etc., it doesn't 
seem an unreasonable yardstick when designing an amp.
