[Amps] AM On a linear

[Bill L. Fuqua]

All of you are overlooking the fact that during the negative swing of the modulator when the plate voltage is near zero  just about all the power will actually go to the grid. The same reason why you should not drive the tube with out the B+ on. You will possibly fry the grid if you don't modulate the driver too.

We are overlloking the feed through RF from the grounded grid configuration.
 A portion of the driving RF will always appear in the output, thus you can never "pinch off" the carrier and get 100% modulation.
