I watched one a couple of weeks back on amps. They used a McIntosh 275. Another great watch ..

Yes, that is an amazing looking amp. I hope Emo Glass presents us with both eye and ear candy like that!

That was very cool to watch,Now I know why tube equipment costs so much.
A lot goes into making one tube,def not a quick process.

Terrific video.
but I suspect that MODERN tube manufacture is much more highly automated.
If it weren't NOBODY could afford tubes.

Yeah that's not the normal tube. Those specific ones sell for $1000 a pair

I've watched too many episodes of "How It's Made". They tend to be filmed in Canada, and I've noticed that some of the episodes are filmed at boutique/small businesses that aren't fully automated.
I would guess that there aren't any fully automated modern tube manufacturers in the U.S. or Canada.

Nice video Jim. I have one from from an old British video. Long video too.

Even with the unwieldy manufacturing processes of 1940, tubes could be mass produced:
Here's another from the 1950s with more specifics on the glass tube:
