Not sure what you mean by self rectification. Is that what happens when
ever a tube circuit such as this is run on AC
Grayson
Yes, when you use AC direct from the plate transformer to the vacuum
tube oscillator this is what happens. It also produces a characteristic
60Hz hum in the corona discharge due to half use of the sine wave
on the plate side of the oscillator.
