Cool video, I thought.


*edit* sorry about that! I have to check and see if I posted the tube video on the football forum.

Not seeing any ehx video?

Oops! Fixed.

Cool Video.  Lots of little parts.

[John]

yeah, suddenly $50 for a pair of tubes seems pretty cheap.

Many steps skipped in that video.

Here's more. It's old and UK, but the techniques and often the machinery is the same.

A bit annoyed how the Saratov plant has hands all over the parts. Yes they are acid-washed and vacuum-boiled at final assembly. But late Mullard Blackburn had no hands on the parts, all automated or indirect handling.

Here's a guy hand-making tubes. Slow so you can see. Nixies, but many of the steps are the same.

Wow, no OSHA in Russia. Kick presses are one thing but powered presses would require two hand palm buttons, light curtains, barriers, and placement tools here in the USA. I'm surprised I didn't see the old yank back wrist straps at least. There may be some employees over there missing a digit or two, or with unintended piercings.

Those flame indexing wheels require some long term expertise. A fuse company I worked for had many of those for certain cartridge fuse assembly processes and in the UK for large glass tube fuses (~12"). Only the older employees with thousands of hours on the machine could tweak it to run right.  Did you notice the employee adjusting the flame nozzles? A constant battle with varying gas pressures and materials. Another case of $10 to show up and $10,000 to show you where to kick it!

Cool stuff!
