Now I have to ask (because you guys got me thinking):
How many people on this list, or that folks on this list know of, have
ever designed a circuit using tubes, or know anything about tubes? It
sounds like analog may not be taught much or well these days, let alone
anything about tubes.
I've used them a couple times. Very rarely though.
A MOSFET is approximately equivalent to a triode tube since both
modulate the current flow with an applied voltage.
The big thing is that a tube is *not* approximately equivalent to a
bipolar. Bipolar transistors modulate current flow with current flow.
I'd rather have MOSFET's than tubes.
