[vacuum tube failures can be spectacular]
I DID get to see a modern radio-transmitting tube about 3 weeks ago. It was the size of
a lunch box. It wasn't a final tube though - I was told the AM final
tubes are about the size of my head. It had a metal jacket so you couldn't
see inside it, but it weighed a hefty amount. It went to some unknown FM
broadcast transmitter.
Biggest one I've seen was about 2 dm. in diametre and
about 4 dm. tall.

It actually looked like a small lighthouse.. ribbed metal at the bottom
with a glass section at the top. Probably lighed up like one, too.
