Default Flame triodes!

I found these after watching the mullard fabrication videos. Pretty amazing, and I was surprised how well it worked without a vaccuum. Any chance of a Mad Max / post -apocalyptic headphone amp?

HAHA that's funny. I don;t think we'll see anything "hi-fi" but as a novelty item, someone must build one .

I was considering a bicycle generator with a step-up transformer for a really crappy B+ supply. The voltage drop on the flame diode is considerable!

I would be more inclined to believe that what you are seeing is the electron's from the heated wire making their way to the anode on their own and not so much with the help of the flame.

The flame is plasma so IE it's conductive and will act the same as a beam of electrons, it's basically the same thing.
