John,

Where did I flip flop? I've always said a grid could not become positive from 
the methods being discussed. So did Terman if any will read the same edition I 
have. Nowhere in the 1st edition, which I have, says a grid became positive. It 
only says "less negative". The quote I made is exactly word for word what was 
in print except for one mispelled word I caught. Once one reads this whole 
section on gassy tubes, and the one that talks about space charge, you can see 
what is really meant. There's only one possible cause of a grid ever becoming 
positive, and that is only for part of a cycle from a grid being driven into 
that region by the incoming signal. I posted this earlier, and wha was said 
about it. The only other would be to purposely place a positive potential on 
the grid. Were not talking about this here, only about what would happen with a 
gassy tube or about a grid which is floating. When Terman says suddenly 
positive, it means suddenly more positive than what it was at
  that moment. It would never go above ground potential or 0 Vdc from electron 
flow. He says this in various other places in the book. One has to read the 
whole chapter on vacuum tubes to see all of this. One can't be like some 
preachers and take one verse from the Bible and say it means something else. If 
you read before and after the verse, you find that it meant something totally 
different than they professed. I've seen this happen before. By what Tom says, 
Terman is flip flopping, or was wrong. Did he lie. the first time? Some how, I 
don't think so.

Best,

Will
