No, glass bottles are unique in that they don't run on smoke, unlike their
sorry-state and disintegrated-circuit replacements, which are notorious for
losing their smoke at just the wrong moment.

In BA radios, the smoke is held within the transformers and resistors, and
sometimes the 'lytic caps. I've been there when it escaped.

I'd always thought that with glowbottle gear, the smoke had to be
present, but kept out of the glowbottles. I suspect that's why so
many hams smoked, and how so many older rigs ended up with that golden
brown color distributed so evenly: they've supplied the magic smoke.

e.g. SQL*Forms. I pronounce that one "squeal splat forms" - sort of sounds
like roadkill, doesn't it?

You forgot selenium rectifiers. You *don't* want to be around when the
smoke escapes from one of those....
