This video is simply amazing!

A French amateur radio operator is hand making his own vacuum tubes. This 17 minute video shows each step in the process. Many of the tools he uses look like he made those, too. He does it all from metal fabrication, glass blowing, final assembly, testing and tuning. It's unbelievable!

That IS impressive! I'm amazed at the patience and determination some people have. Those are qualities I'm woefully defficient in.

I'd like access to the machine shop and all the cool tools he put together to do it.

How many people remember what a 12AV7 and a 35W4 tube did?

I'll bet fewer people know what a CK722 is (hint: it was introduced by Raytheon)

Hint number two: It wasn't a tube:rolleyes:

It is funny that he is making his own as you can STILL get them commerically. In fact there is a new market for high-end TUBE driven CD players and even DVD players!

I need some for my old radios I have one from 1936 and a couple from the 1950's that have each burned something out. What I need is a TUBE TESTER... anybody remember when they were everywhere?


Now for crazy was my friend's grandpa. He claimed HE had invented the "modern" lightbulb and made hiw own in the basement of his house! He would not buy them from the people who 'stole' his patent -- you know like GE :rolleyes:

What's the point of processing a square signal from a CD or DVD through an anlogue tube amp?

12AV7 - Dual Beam-power pentode?

35w4 is used in the power rectifier stage of a simple (crude) tube amp
12AV7 is a detector/amplifier tube (first stage)

Common in small tube radios and record players. Even in low power (under 5 watt) guitar amplifiers.

I love basking in the glow of a pair of overdriven 811 triodes!

impressive.. An art in itself

I hope to have a nice radio set in my rumpus room... My grandpa has shown me pictures of the big radio they used to have in the living room... they would listen to the news and everything on it... My great grandpa had one of the radios in his house before he passed on, the sound from it was great.. warm as well... tubes for life
