This is a video of a guy who makes his own tubes as in valves in the UK. Looks like most of his gear is home made and he knows what he's doing. Damn near every tool he used looks home made to me except the lathe at the very end. I found it fascinating.

Seems on-topic to me:)

A mixture of finely tuned hands-on engineering skills there, no computers, cad, DRO's, PLC's its all done manually.

Hate to think what he charges for a valve though:eek: ?

Truly a labor of love. A real craftsman.

How do you get these valves in your tyre then ??

Holy cow! That's amazing! He isn't just making electronics parts, he's making collector's items. Imagine what they will sell for after he dies.

Checking out his web site it appears they were a one time project to celebrate the centennial of the first triode made by De Forest in 1906.


From French by Google

Lovers and respectful of old and venerable components, it revives tubes receipt of 20 years to make them 3 watts in the band 80m in telegraphy.
Des QSO dans toute l'Europe seront réalisés...
The QSO across Europe will be made ...
V
His reverence for equipment Mr Arthur Collins, leads to restore a number of transmitters and receivers Collins, and especially the 618-T.
And then, is it to participate in their own way to the centennial of the invention of the triode by Lee De Forest in 1906, he launched himself into the manufacture of mythical TM developed by General Ferrié in 1915. Make a lamp, it's not so easy, but for corser a little difficulty, F2FO will build everything needed for this project, and in particular various pumps, including a molecular order to get a gap, allowing employment in emission tubes made.
A dozen lamps will see the day ...
To check the measurements, a QSO will be implemented on 1 January 2005 on a 80m CW between Montrouge/92 and Camaret/29.
Les tubes sont robustes et feront d'autres contacts...
The tubes are strong and will be other contacts ...
The initial aim, which was to cross the Atlantic, was hit by F6BWO who has made many QSO on 4 continents.

Best video I have seen this year!

Loved the little spot welder,the homebrew vaccum pump wasn't bad either.

Punctures in your tyres, valves in the tubes John.:)
It took the best part of 1/2hr+ to download on my high speed broadband connection but it was worth it. Impressive video!

This is the third time that video of the French guy building hand-made triodes was posted here. Evan, you posted in the previous threads :)

Mad man, scientist, genius, wizard ? Watch video and see for yourself ! (http://bbs.homeshopmachinist.net/showthread.php?p=326715)

That spot welder is perfect. I have everything I need to make one so it goes on the list...

Yes I did. I didn't watch the video before though. My satellite connection is only good enough for that long a video very early in the morning. You will note I didn't comment on the video either.

I've watched that video several times, always have the same fascination,

Not sure if I caught the first thread on it or not, originally found it when I was looking for information on those tuning indicators that used to be on the front of the old tube type console stereo systems. Never did find out exactly what they were called, but found enough of interest that I didn't mind.
(not the meter type, but either lights that got brighter, lines that got clearer, or a pair of lines that would diverge or align depending on how well tuned you were.)

Ken, the Triodes he's making are linear amplifiers. He's actually trying to match the linearity of the triode against an "off-the-shelf" (reference) part.

That was the first thing I wondered, when I saw this video when it was posted on PM last Fall: how the heck do you match these hand-made tube amps??

By the way, here's a Google translation of Claude Paillard's web page:

It was made by RCA and they called it the "Magic Eye".

If you Google magic eye tuner you will find all you ever wanted to know.

That's the things! My google skills were never that great.

Something to be said about the old tube systems, they looked neater, and seemed to have a warmer sound to them.

Thanks
Ken.

Those sure look a lot like WD-11s, the tube RCA used in the Radiola receivers of the late 1920's. Very rare and expensive now, I have a Radiola III in the garage, minus the WD-11s. If I had the tubes they would be worth more than the radio. There have been substitutes in the past, "modern" tubes that were rebased, but no one made new replacements. I think that's what this guy is doing, and it takes an artist/craftsman like him to pull it off.
