    Automated production line machinery must be fearsome.

    Never realized how much precision hand work was involved.
    Assuming all tubes are made this same way, $15 - $35 for a standard audio tube seems like a bargain.
    Cool post

    Thanks for the link! I love that show ("How It's Made"). My entire family is addicted. They do an excellent job telling about how a huge variety of things are made, and they do it in an interesting and pretty efficient fashion. They've done a ton of music-related features, as well, including Gibson guitars, and one on cymbals (Zildjian, I think?).

    Great skill in those workers hands. Those high end tubes like the 845 in the video and the 300B sound amazing.

    Cool. I have never seen the process and did not realize how much skilled handwork is required. Thanks for sharing, John!

    Here's another video, along similar lines, featuring the Mullard Blackburn tube production facility in England.

    Amazing. Lots of skill involved.

    You would thing the variability across units would be relatively high given all the handwork. I guess that is part of the beauty of tubes, each one sounds a bit different I guess (at least the ones made like this).

    Yup....cool video John, thanks.

    I have seen quite a bit of glass blowing done up close and in person as there are quite a few artisans here who do that stuff, although most of them just make pipes and bongs.:smug:


    The coolest part for me was how they get the vacuum in the vacuum tube and take the impurities out. Always wondered how they accomplish that.
