This crazy person, French radio enthusiast Claude Paillard, makes his own vacuum tubes. Ooh. This video’s been kicking around the internet for a while, but if you haven’t seen it, it’s worth at least the time it takes to watch it.
The process is quite beautiful. So much precision, patience, and attention to detail.
Paillard’s website is full of writing on tubes and radio, their history and their function. There’s even a detailed guide to making a vacuum triode by hand, just like he demonstrates in the video below.
