There's no vacuum in a Nixie Tube!
That being said, it would be nice if classic tubes of yesteryear can be remade efficiently. Especially for antique radio enthusiasts.
- inlined 10y agoWhy do you say there's no vacuum? That's one of the steps in the videos.
- dekhn 10y agoTechnically, at the end of the process, the resulting tube's gas pressure is high enough to be called "low pressure" rather than, say, "rough", "medium", or "high vacuum".
- fake-name 10y agoUh, what? Production involves pumping down to high vacuum, heating to degas, and then refilling with neon/argon at low pressure. Granted the production tube isn't at high vacuum, but it's not equivalent to ambient.
- erikpukinskis 10y agoWhen they fill it with gas, wouldn't you say it is no longer a vacuum?
- makomk 10y agoNo theoretical reason why r couldn't be done, I think the more common guitar amp tubes are even in commercial production in China (and supposedly they've improved the robustness too). Bit of a niche market though. glasslinger on YouTube has been experimenting with making some of the more unusual tubes too: https://youtu.be/BXAjspPLzRQ https://youtu.be/BXAjspPLzRQ
- 3chelon 10y agoThis entire class of technology was universally known as "vacuum tubes" for a good reason.
