Triode radio tube: do it yourself

In these days of hitech electronics we have lost the ability to manufacture our own components.  Too complicated, too expensive and not worthwhile, because there is a mass production facility doing it for you.

Building your own equipment of standard components is also becoming rare, the chinese factories do that for us.

I have personally done nothing with tubes, it started with transistors for me (Philips Pionier!). Fascinating early electronic technology, and audiophiles still listen to tube amplifiers.

Why this fascination for tubes now? I found an instruction video how to make your own triode, one of the most simple tubes, but requirig knowlegde and craftmenship.  Claude Paillard makes his own tubes, and tells all about that, includg books and a (long) video how he does that.
