An absolutely great and gorgeous video about selfmanufactoring a triode tube!

- Eckhard

That was so KOOL! Obviously this guy has spent a lot of time in this effort. He heven uses a mercury vacuum pump. I have never actually seen one in operation so this is very very KOOL! I wish there was a subtitle narrative explaining the technical aspects of what he was doing and why. But never the less it was most educating.

I wonder why he put all this effort into this. Could he possibly be a tube rebuilder or in some related industy. Looks like a lot of his equipment was custom fabricated to do this project. Man, thats dedication!
