#188199 - Voltage-controlled
Responding to: ???'s previous message

My knowledge of pentodes is pretty rusty
for those of us that started out with tubes/valves (after designing a radio with tubes, I was involved early in my career with the first transistor radio made in Denmark) when the FET came around, we, with a sign of relief said "that is just like a tube". Maybe using that in reverse will be a help.

Don't come and try to convince us that vacuum tubes are voltage-controlled, having voltage potentials on plates/grids regulating the current flow ;)
