This is so amazing! So many craftmansships in one Man. Glass, electronics, mechanical and videoproducer. (And a lot more, manuscript, producer, cameraman)

Could watch this mastery of craft for hours - It's like "The Joy of Painting" for enigineers :=) Love your work!

These tiny tubes were the key components in the proximity fuzes used by AA artillery in WW2. It was found that by mounting them vertically in a rubber mounting they were able to withstand the 30,000 G of firing stress. They were invented in UK and then went across to the US with the Tizard group along with the cavity magnetron.

Your work with building valves & Nixies never fails to amaze me.

FANTASTIC VIDEO! I was a teenager in the nineteen fifties, at the end of the vacuum tube era, and I built and repaired many tube radios, amplifiers and TV sets before the transistor took over. But, I could never figure out how they were able to seal a vacuum in vacuum tubes. It seemed to me like the hot molten glass would be sucked into the tube by the vacuum pump as the tube was sealing. Or, the inrush of air would cool the hot glass at the point where it closed and prevent it from sealing. I knew the "getter" was used in the last step to harden the vacuum, but it was obvious that most of the air had to be removed with a vacuum pump. This puzzle about vacuum tubes has bothered me for more than 60 years, and I've tried to look up an explanation with no success. Then, I came across your video by accident. Now that I've actually watched you seal a tube, I still find it hard to believe it's possible. Moreover, it's such a delicate operation, that I'm amazed they were able to automate the process and make vacuum tubes by the millions and sell them so cheap. Thank you for finally clearing up this mystery for me after more than 60 years.

Would be cool to put the triode into an am transmitter circuit. I would be curious how many mw (or even watts :)) it could output to a 50 ohm dummy load. That is some precision work there! Thanks for another great video. Please keep making them and we'll keep watching!

Incredible amount of patience and knowledge. Thanks for showing this great hand-made work of functioning art!

Just Amazing, Mind Blowing, A true Old school Engineer..

Nice piece of craftsmanship by an expert electronics technician. Excellent job !

How can anyone downvote this excellent example of craftmanship and engineering? Thanks for everything Mr. Ron.

would have like to see it finished & working !!!!! anticlimax

I am not worthy! Thank you for keeping the history of American craftsmanship alive.

A great job. Congratulations from Chile!

You have some great skills man, thank you for sharing them. I appreciate the effort you put in to making these great videos. all the best.

Fascinating- as always!

Recreating a lost art. Thanks for posting!

That is craftsmanship!

Hey Ron, you got a new camera! We could see that 1 mil filament just fine! Would sure love to see these pygmy tubes used in something.

I was on the edge of my seat the whole time!

Such tiny tubes could be used to make a tiny amplifier for the tiny violin. (or other tiny musical device really...)

That had me on the edge of my seat, and holding my breath at times!

This is such a neat project. You have great skill and patience. Thank you for sharing with us!

WOW!!!!!! That is intricate work. If Lee Deforest, the inventor of the "audion tube" way back in 1904 was alive today he would be blown away by this video.

Amazing work as usual! I would love to see a video on your DIY Transconductance meter.

Ни секунды не сомневался, что геттер сделает своё дело, как надо! 😊💓👍 Thank you for your passion!

Dang, you have steady hands and fine motor control of a teenager‼️ I can't have fun with what you're doing because of my tremors!

Glasslinger is a master craftsman. That's enough. But he also can build this stuff in front of a camera while keeping everything in focus. That's genius.

What an awesome video.....such skill and craftsmanship!!

Amazing stuff. Proper craftsmanship

You are a mad scientist, I love it...!!!

I admire your skills and craftsmanship. Just beautiful. Thank you for sharing it.

Wow! That's amazing!

This is a very informative and entertaining video. thanks for sharing !

Genius at work. Absolutely Awesome video as always Ron. I can't add anything more than the other good people who have commented other than I hope we will get to see the emission results soon in your next video for the triode. I agree, a transmitter would be a nice project. Maybe a 20's period looking receiver that you are a master at creating would sell better however.

Unbelievable! Looks like Witchkaft :).

Hey Ron, great video. That was like tying three knots in an eyelash! awesome work. Kind regards Paul (Netherlands)

my mind is blown... pure awesomeness!

Damn that is fine work !

ONE OF THE BEST CRAFTSMAN EVER.I enjoy watching Ron works.Very Knowledgeable.Thank you for a great video. 73 KI7DYM

You are having brilliant skills sir. Now I have understood why vacuum tube amplifiers are expensive. Because your love in your work is visible. Now a days everything looks magic. I always feel there is a life inside the vacuum tube radios. Same in the case of old wall clocks. Thanks for making such historical videos. I have become your follower. Kindly share your Photograph. I would like to add in my best mechanics album.

Thank you for sharing this!!

Searching the net, there seems to be no known cure or treatment for this kind of illness!! [kidding] :) Simply outstanding !!!

u are a mad scientist. I LOVE IT

Vacuum tubes the size of Christmas tree lights

Amazing work Bud Big Respect from Birmingham England

That's impressive. It's jst so cool that you can make things like this!

Man thank you i was searching for hours

Tiddlywinked off into oblivion! I love it

An old video, from a time when I should have been interested. Alot of time lost. Alot of life gone by, nonetheless just as useful, albeit for more psychological processes than material. In any case I am thankful to you.. from a weird and dangerous future..

just gave it a thumbs up without watching the video, just because i knew your previous videos ;-) after watching i could need a secound and third voice to vote... Ron, your videos are just very impressive. I would like to see the final result of your mini-tubes. Did you put them on a wooden stand for an exposition? Please upload videos of your projects more frequently.... Greets from Germany Ronny

Muy buen trabajo, felicitaciones.

He'd be great in a sci-fi series about rebuilding the world post "what it was" that happened.

Hi! Ron. Can u show your antique radio collection to your viewers that u have reconditioned . It will be very exciting to see your collections.

thank you hope you have been doing well good work always enjoy your posts

It took me a few seconds to remember the tiny triode tubes RCA ever so loved, nuvistors. Only ever saw one fail, out of thousands. Unlike vacuum tubes used in car radios and portable electronics like hearing aids. Folks, think hearing aids twice the size of a Raspberry Pi case alll around, powered by a 90 volt battery.

Adorable!

This awesome, but I've never had so much adrenaline watching a DIY tube video. ITS SO FIDDLY XD

Nice. You may be able to optimize the process with jigs. Not sure of the tolerances of the application but space between the elements can affect performance. Jigs may give more control of spacing. Amazing.

wow. very good job, I had been looking for a video like this for ... I also wanted to try to manufacture one. One question: what is the substance that covers the filament? thank you very much, greetings.

You have a lot of initiative...

im so hapy i found you on you tube. you are an true artist. Nice

New Camera? WOW Good Quality. Way better than Before ^^

I love it.

every "ok" spell give +1 to emission and +0.5 to gain =)) ( to say without joke - this is AWESOME !!! great ! )

Make a 1921 Peanut Tube! These 'improvised design' tubes used a control electrode on the outside of the tube to circumvent patents, or just a cheaper means of fabrication. They controlled their electron stream by means similar to CRT's, but with lower anode voltages(15V to 22.5V). Just little incandescent lantern bulbs fitted with three connections at its base, and a wire electrode wound around the neck of the bulb's midsection for the input signal. Low gain and high impedance, kind of like a crude vacuum-tube version of a FET

I love your videos and the glasstubes you are making. Splendid!

I wish you had explained an application where these could be used, say to replace one of those great big diodes from the fifties or something like that

Very good, really fantastic! Yes it is a real Craftmanship! Mr. Glasslinger, do you use a HHO generator? I hear Some noises like electrolysis Just Bravo for this DIY!

Nice job! I love Your videos! I am going to try tube making. I make neon signs so I am more than half way there. I just made a small induction oven, which is my last stumbling block. I will post a video when I get there.

Vacuum tube manufacturer ASMR 😍

Hi Glasslinger. Great Video. Could you please tell me what welder you are using please. I have looked everywhere for some info on one. If you could please help me it would be greatly appreciated. Thank you. Have a great day.

This is captivating. It is a master class in an anachronistic art form. I'm mesmerized. I call this is a "cozy" technical video. Enjoyed every minute of it. Thanks a lot, Glassslinger! And stay fabulous, no matter what those dumpy, greasy dudes think ;-)

Awesome work as always. Did they work at least?

Jesus man, u gotta have alot of patience for this.

I think if you took some glass capillary tube you could group as many as you need in a bundle and melt them together with the tungsten wire inside. Then you have a nice straight base. You could even fill them with vacuum epoxy instead of melting the glass to the tungsten.

"tiddly-winked off into oblivia" haha, never heard that phrase before.. you are hilarious!

so cool to be able to do that, but how do you calculate mu and other values?

Wonderful, mesmerising to watch first-principles craftsmanship like this. I'm really intrigued with your miniature handheld spot welder, is it commercial or did you build it? If so, what sort of transformer was used as I'm guessing a modified microwave oven tranny would be grossly over current for these tiny zaps?

Pure magic

awesomeness.

Awesome! Can I ask how much filament voltage and current you were running on the diode?

amazing

Books I've read from RCA and Phillips have you flashing the getter after sealing, FWIW. Perhaps that's to avoid reheating (and redistributing it) during sealing, causing electrical leakage, etc.

Wow. Stealing bits out of tubes to build even smaller tubes!

Mouth noises adds to the professionalism....

where do you get the nickel tube from?

Where did you get that bench top vise from? I’ve looked at PanaVise and did not find anything looking remotely similar.

Great videos. Where can I get the flash getter from. It looks like you have a getter designed for a larger tube that you have cut to size. I understand it is made from Barium Azide and powdered glass, but tracking down this kind of thing is going to be very difficult.

Outstanding! Where do you get your materials?(glass,tungsten wire ,nickel tubing etc.????)

We see it. :)

genius

wow!! I would like to know the pic is for what article? I'm sure its of big interest to me!

Fantastic! What is the product that covers the filament? Congratulations!

you are funny as hell :D

This is WaaaaaaY COOL !! ( This is a Must - Watch !! ) If you are a Totally Geek'd Out Electronics NERD,...... You have to see this old school method, for making " Hollow State " devices !!! Great Job, Well Done !!! PS: Can anyone tell me, where I can get the materials to make tubes ?? Like Thoriated tungsten wire or the chemicals used for treating or coating the filament and getter. Also, where can I find the metal wire, tubing and sheet's of whatever pure or alloys used in the construction of the diode, triode, etc........! I want to design and build a Nuke/EMP Proof Tranceiver !!

looks like I have most of the tools to do this is a diffusion pump absolutely necessary?

are you using Cree graphite to melt the beads together .it looks like Cree to me

What is the lifetime of these tubes. Is the temperature coefficient of expansion the same for tungsten as glass? Do you get leakage around the pins when the tube expands and contracts?

Is this a useable tube? I have some 4 conductor micro tubes that were supposed to be stock for hearing aids. I wanted to build a tube compressor pedal for guitar but I've never figured out how to use these tubes without tons of noise. There is no dedicated heater pin.

what liquid you mix with your barium carbonate to make it stick on filament?
