"Valve" is a lot more accurate to describe the function of vaccuum tubes,
when you think about it. "Tube" simply describes the shape of the
"container" of the item, but "valve" is exactly what a tube does-- control
the amount or flow of electrons. I think it's a much more appropriate word
for a basic building block of circuits than tube.
