Rolling his own

A couple of people sent a link to this clip about a Frenchman who makes his own vacuum tubes starting from glass tube and metal stock. It's 17 minutes long and I found it fascinating - not that I expect everyone will.

I also enjoyed the first comment about this clip; I'd like to see someone make a FET in a home workshop too.

This is the most amazing piece of work I've seen in years. Truly amazing. One man and a whole host of equipment, some home-made, to produce a suite of triodes. I shall never look at a common store-bought triode in the same way ever again.

Now let's see someone build a Field Effect Transistor (FET), the solid state equivalent of a triode, on their kitchen bench!
