Another way to think of tubes is big delicate airy
capacitors with heat
in the middle. They sure look cool though, and things like big 811's,
the very idea that the carbon plate is glowing cherry red merely from
SLOW ELECTRON BOMBARDMENT! is Very Cool!
If you think 811s are big, you need to get out more.
