Make your own vacuum tubes?

Fabrication d'une lampe triode
by F2FO

This French ham makes his own triodes. The link has a movie of him doing just that. And he does a noce job, even shows the final product working.

It's a long video at 17 minutes, but worth looking at. It was first blogged on the Make Magazine website. The first magazine devoted entirely to do-it-yourself technology projects. If you haven't heard of the magazine, check it out next time your at Barnes & Noble.
