Fascinating video of a man making a vacuum tube!
Video of man making vacuum tubes.
He didn't make this tube, but it sure looks cool!
(Credit: Steve Guttenberg)A friend turned me onto this amazing video of a man hand crafting vacuum tubes. He makes every part, the metal structures, blows the glass envelope, the base, pins, everything. It's a hugely labor intensive process. I just love that there are people out there doing this sort of thing, almost the same way it was done 100 years ago.
