Ode to a triode

Following up on the theme of craft videos posted earlier, here is an amazing one.

The french radio amateur Claude Perrier decided to celebrate the 100 years anniversary of the invention of the triode vacuum tube in 1906 by De Forest, by making his own tubes based on a design from 1915. And yes, he also built all the necessary tools, including the vacuum pump.

Wow, I watched the whole thing. Now, what does triodes really do? Or did, rather, I guess they are not around anymore.

Also, O.K. - is "Dead finks don't talk" a bird song?

Triodes, put simply, are used for amplification in electrical circuits, a predecessor to the transistor. Vacuum tubes/valves are nowadays only used in some radio transmitters and in audio(phile) and musical instrument amplifiers.

"is "Dead finks don't talk" a bird song?"

Dead finks don't sing either... ;)

Amazing, beautiful! What a handicraft and all his homemade gear, simple, primitive but does the job.
