How It's Made - vacuum tubes

For some reason, I LOVE the show "How It's Made" and this segment is a beautifully shot piece on how vacuum tubes are made. These tubes are being made in the Czech Republic for audio gear and it's amazing how much hand work goes into their creation. They almost look like sculpture.

As a cinematographer who used to build vacuum tube amplifiers in the last century, this video was a lot of eye candy. It also unveiled a few mysteries, like how the getter is fired when it's sealed inside the tube. Great content, and nicely portrayed!

Hi Bass. Thanks for the feedback. Also wanted to say "Hi" as I've corresponded with you over on DVInfo.net, too.

[basspig]

@morrisonAV I've never posted on DVinfo, so perhaps you have me mixed up with someone else. Or perhaps you mean DVXuser?

@basspig

That must be it. I saw your name mentioned there in a thread on DVInfo. Miight have been referencing your posts in DVXuser. That's probably where I've commented on your threads re: the EX1.

I was the film crew - director. Found the subject too. Czech Republic.

@murdepierre Beautifully shot and edited, murdepierre. I'm in the early stages of shooting similar projects so your work is a great learning tool for me. Again, well done!

[basspig]

@morrisonAV Very possible. I was vocal about the bad audio on the Sony V1U. Am now a happy camper with Sony XDCam lineup and Atomos Samurai HD-SDI recorder.

@murdepierre

Murdpierre, were you on the film crew or did you work at the tube maker?

These look so damn expensive.

I know - awesome. I was there for the filming of the segment.
