That god damn awful background music annoyed the shit out of me... Nice video though.

That is interesting, I was thinking this was one of the only videos whose background music didn't annoy me. I felt it matched the pace of the work pretty well.

I remember seeing this video years ago and being impressed as hell. I wonder if he's still at it, and if he passed any of his knowledge on to an apprentice. It would be a shame if it all was lost.
There's still a number of people who make their own triodes. Triodes were used into the 60s and were still made by hand on assembly lines until the 50s. The people who made these tubes are still alive.
Plus, tubes will never die, ever. There are just some things you can't do with semiconductors. X-ray sources, (good) photomultiplication and electron beams just to name a few.
