How Its Made - Vacuum Tubes

[JRKO]

This great little video has really increased my respect for the 'tube' - I gotta get some tubes into my life!

Great video.

You're late, I already posted this five pages back. "Making a Kron tube"

No wonder the things cost so *#)$)*( much.

Wish I could afford even 1 of those tubes. I guess we can say thats not a tube FACTORY?

Cheers,

Nice video, thanks! I've seen those tubes in person, they are quite impressive.

(Strange accent the voice-over guy has)

That's a lousy promotional video for some crappy "hand made Audiophile" tubes.

If you want a video on how vacuum tubes are made, you can do better.

for example:
Mullard - The Blackburn Vacuum Tubes Factory (Full) - YouTube
or http://paillard.claude.free.fr/

I wish there were better videos, I'm sure they were made. They're probably lying in film cans in an archive somewhere.

What's your beef with KR? You complained the last time that video was posted.

 

[yajnaS]

I did ? I don't remember

found it (the previous post). Nothing personal against KR, I just find the video annoying.
Some part of that video is just bad. e.g. their description of the getter flashing process.

Just a bit of trivia..

I never thought before where the Mullard name came from..

Well don´t look at it then!

Yup--the description of various processes is directed at the total 'man-in-the-street' who hasnt a clue on anything technical!

If it was re-worded with a technician in mind, most of the target audience would turn off!

 

[Pano]

Thanks for the Mullard article. I knew almost none of that.

As for the video, I think KR was a good choice as the valves are big and made by hand. Makes for good video. Still, it would be fun to see old footage of a factory like Mullard that was making millions a year.

They produced some triodes for the European Triode Festival 2006.

Watching all these tube making videos shows that you need the essential ingredient of heat, and more heat. And spinning gadgets. A spot welder also seems essential.

Yes, very interesting video.

What struck me the most is how long ago England used to make stuff, stuff that China is making again today. So much of a better business environment in China.

I think it was 6000 workers in the factory at the time...look how much we lost with the transistor..LOL

Well don´t look at it then!

It is worth looking, while commentary sounds silly. Tube amplifies because voltage between anode and cathode is higher than signal! Eureka! Just mute the speaker.

I found it interesting,

If you look at the machinery the amount of adjustments on the M/C's that must have needed maintenance..

The pin forming on the base all bent to the correct angle for the connections..

Then again the woman with the tweezers welding the cage to the base..imagine doing that for an eight hour night shift..
