As for delay, I suspect that the kind of periods involved in

Delay, if included in an algebraic (including SPICE, etc.)
model that also includes "inherent triode feedback"
would imply some(* ps later maybe) tendency to oscillate.
Maybe that's why it's not included.
Where we are now, for all practical purposes, is likely to be the end
of the story.
And yet, having despaired of the topic and this newsgroup,
and life, the universe, and everything, I've read recent
interesting stuff and despair has faded into...
What's the word?
Much thanks, as always,
