The Manufacture Of Radio Valves (Vacuum Tubes), By Mullard

This film, made by British tube manufacturer Mullard, shows how they made their famous vacuum tubes (valves). If you're a fan of vacuum tube audio gear, you should watch this to see how tubes were made back in the day.

This was fascinating Scott. What a gem. I’ve seen lots of how it’s made videos but this one I think has to be the best. Thanks for posting.

Thanks. I finally got my time machine working and went back some 70 years to make this film myself. The hard part was explaining what a "smartphone" was, and how I could shoot high-resolution video with it. But of course, to evade suspicion of being a time-traveler, I had to make the film look like it was shot in the 50's.🤣
