Hi Will,
If Mr. Harper had a (1937 or 1943) Terman book in his references it
would have saved him considerable research.

Pay close attention when reading this about the only possible way a
control grid could become positive. It's under the portion about how
a triode works. The control grid has to be heated hot enough to emit
electrons. Under normal operation, a tube will be at cathode
potential Vg = OV, or under Vg = -10 Vdc, etc. This is a very long
article, but a good one.
