- Eimac's data sheet says that the 3CX800A7 has a plate dissipation of 800 watts. But then they say that it '...will deliver 750 watts PEP and 750 watts keydown CW output to 350 mHz'. I don't think the

- Data sheet shows max Plate V=2250 and max Plate ma=600. Typical AB2 use is Plate V=2200 and Plate ma=500 Typical Usage 2200 X .5 = 1100 watts in at 65% efficiency = 715 watts out. Max Usage 2250 x .6

- The 750 watts is "useful power output," i.e. output after plate circuit losses. The real kicker is the MAXIMUM rated plate current of .6 Amps. With Max E and Max I that's 1350 max watts input or may

- The Eimac data sheet for the 3CX800A7 was an after thought. The tube had been developed and rated at 1370 watts output with "typical" operation at 2500 volts at 800 ma. THEN the FCC changed the power

- Terry, If the tube was designed for opration at 2500 volts 800 mA, why does the data sheet/catalog give 2200 volts 600 mA as "maximum ratings?" Why not simply show the lower "typical operation" numb

- My Eimac catalog shows essentially the same tube, the 3CPX800, rated for 3500 volts at 8 amps maximum (short pulse). I don't have the full data sheet so I can't make any determination of the average
