Maybe greater than your mind. If any of them claim what you are
claiming, their minds are definitely not greater than mine. There is
dynamic equilibrium in a triode, that some may loosely, maliciously,
dishonestly, or foolishly call NFB. I have accepted all along that
this loose definition has currency, as you will see if you read my
posts.

If there is not an internal feedback loop in a triode, how is it that
breaking the loop with a screen increases the gain?
