Tom says:
>The tube also draws less current, because HV is less.
No. The tube draws maximum current when the plate volts are minimum, and the
grid the most positive (which may not necessarily be positive with respect
to cathode). So it's swing that gets cramped - the minimum plate voltage
shouldn't move that far.
Especially in a tetrode, gain is loosely related to plate volts. That's why
you modulate the plate and the screen.
