Hi Will,
when the grid is kept grounded it can not become more positive then the
cathode if that is grounded and not negative biased as well, except by RF
drive on it above its choke.

Peter,
On that, I agree it's the only way to make one positive (for only part of a
cycle). Are there any other ways to make the grid positive and the grid be
at ground potential with the cathode at ground? A lot of amps cathodes are
at ground potential unless biased.
Best,
Will
