i was curious about my uncalibrated output meter so i scoped the output of a 100 watt rig and then out of my amp running 3000 v on 2 813's i used rtty mode for a solid carrier. the 100 watt rig read 200 v pp which works out to 100 w the amp with 3000 v plate,apx 700 ma put out 550 v pp which is appx 750 w using same math. i thought it would be higher. the meter built in was caled yrs ago with a good watt meter reads over 800 but i trust the scope.you guys who know amps,does that sound right? and, any guesses what the plate ac volts would be?? i have 5000 volt probes but im reluctrant! maybe half that power? and btw i tried tuned inputs on the amp and rig swr looked worse. didnt see any improvement what should i see?
