My gateway video was the one on the Tefifon - ▶ this video - a consumer music playback format. Production ended the same decade we stood on the moon.

The coolest thing he's covered, I think, that I'd never heard of before is the tefifon: ▶ this video It's basically a continuous loop of tape (similar to an 8-track) but with groves recording music (like a vinyl record). It didn't see much popularity outside of Germany and then was essentially obsoleted by magnetic tape. Such a fascinating technology though. In a parallel Universe it probably would have been vastly more popular.

If you want another rabbit hole to start down, I can also recommend Techmoan. He doesn't do teardowns, but instead likes to buy old HiFi gear and reviews them. Some of them are incredibly obscure such as the Tefifon: ▶ this video

Speaking of forgotten audio formats: Tefifon, old german analog loop of elastic, non-magnetic, tape. More or less ``8-track meet vinyl''. ▶ this video [link]
