Default Mullard Blackburn Tube Factory Tour Video

Found this link on the asylum.

VERY cool video of an old black and white film of the Mullard Blackburn tube works! Very cool tour through how vacuum tubes are made. Amazing to think all those machines were thought of and drawn by hand before manufacture. No AutoCAD back then! Wow!

The video is about 1/2 hour long if you have the time to sit through it I highly recommend checking it out! The audio is a bit hard to understand. You have to turn it up a bit to hear it clearly.

Would love to see more videos like this. I saw the one where the guys hand makes the tubes. that was cool. anyone know of anymore??

Even more interesting is that they are thinking of making valves again.
