My grandfather owned a radio repair store during WW2. I remember him telling me a story of him having to build his own tubes during the war as they were rationed and only allowed 1 replacement tube a month. None of the other repair stores were able to fix as many radios as he was cause he was making his own. As a kid growing up I always thought his workshop would of looked like Einstein's laboratory.

You didn't throw ANYTHING away! The generation, now, throws EVERYTHING away! I pick up beautiful antiques off the side of the road and just a little TLC and they're just fine!

Everyone who collects vintage radios is lucky because they all teach you something, especiallywhen you open them up and see their insides.

@@absalomdraconis i love the simplicity of the macheinary in the video.

I'm blown away by the making of the tubes themselves. I had no idea you could just do that by hand!

As a kid i listened to refurbished tube radios 📻 for hours every day and only had to replace 2 or 3 tubes a year on multiple sets. They held up well.

To meet you and watch you work in your lab would be the highlight of my 75 years on earth. It would be tantamount to meeting Nicoli Tesla!!

This is incredible! The level of your DIY ingenuity is extraordinary! I love all your home made tools and devices. So cool.

Awesome job dude... very rare to see such skill today. in a world of tinkerers that simply buy an Arduino or PIC and plug it in then claim to be nerds... THIS is what tinkering is. raw and true. get yourself a Patreon set up so that other tinkerers can support your content and enable you to help fund future projects. Good luck and keep it going!

I'm speechless! Perfect!!!! Thanks for showing your perfect skills. Even the music fit's perfect to this time. 🙏🙏🙏🙏🙏

Genuinely taken back by this. Great build.🎉

Awesome, proper homebrew, all it needs for perfection are homebrew resistors, caps and transformers.

Resistors (at least for the low values) _would_ be interesting. It's possible to make them from pencil leads (for old fashioned "lead holders", not from actual pencils- you can find both leads and holders in artist supply stores, as that's the only field that still uses them), a bit of wire coiled around the far ends of the lead (separate pieces, to form the electrical contacts), and a bit of solder to hold the wires still. You'd want to paint something insulative on for safety, and maybe some colored nail polish on top of that to color-code the resistor value, but fairly simple. Might be possible to do the same with mechanical pencil leads for higher resistances, but that would be fiddly work, and some might not be conductive at all.

One of the greatest things ever uploaded to youtube. I'm shocked at how great this is. The songs at the end and the dual use as a light source...that's great.

Amazing DIY project! Any mission to colonize another planet will want people like you in the crew.

It’s hard to believe your eyes that this can be done at home. Bravo.

This is by far the most fascinating video I've seen on tubes. Thank you for taking the time.

Love your improvised tool set (specially the induction heater in the knife box). Just shows how important is the skill to use any tool properly really.

I absolutely love your Fallout 4 Pipe weapons style of cobbled together tools like your spot welder. Everyone can spot weld with a state of the art spot welder from a shop but this is amazing ! The parts of this welder are straight out of a dustbin or found in the gutter... perhaps even the cat might have dragged some parts in ! Absolutely Impressive !

I love it. Handcrafted amplified you have made. Great.

Did I intend on watching this entire video when I clicked it? no. Did I watch this tire video anyway? Yes. Is it now 3:30am? yes... Did I subscribe? Well, Duh, Of course I did. This video was amazing, and the content withen is honestly very interesting to me. and somehow you managed to catch my attention for the whole video, which is kinda hard to do sometimes.

TOTALLY AMAZED at how well you have done, at a cost and time investment drastically less than what I have done. I am trying to find a way to email you to offer help with your endeavor but no luck so far. I guess they want to prevent spam. I'll see if I can figure a way. Don't give up! You are well on the way to being an expert! :)

Wow! Thank you so much! I have been watching your videos for around 10 years now. I have a channel email address jdflyback(at)gmail(dot)com. I have not been able to get oxide cathodes to work. I think I wil have to put together a high vacuum system for that. The pure tungsten cathodes do not seem to mind the poor vacuum though.

@@jdflyback re oily vacuum pump: have you heard of a Sprengel pump? It uses falling drops of Mercury to entrain &remove gases. Slow, but very high vacuum is possible, no moving parts or mess. With your glass skills, you could easily make one. There's an article in Wikipedia, and Cody makes one on his channel, Cody's Lab. I wonder if warm, molten Gallium would work, it's hard to get Mercury now.

fabricar tubos debe ser una arte casi olvidado , se debria conservar este video para las generaciones futuras

Captivating build. I am blown away by your ability to make those tubes.

very cool, I never in my life would have considered making my own vacuum tubes, great ingenuity with all the home built equipment as well!

I'm speechless. I saw some videos of making homemade vacuum tubes, but this one... For me it's unbelievable what people can produce at home. Really nice job, nice sound (for homemade tubes) and great video. Keep on going.👍 Greetings from Czech Republic 😀

I was glued to this one - fascinating. And I loved the way that virtually all your tools and jigs are home-built.

Very Impressive, especially the two tubes. Welldone

The breadth and depth of knowledge, skills and experience shown here is mind boggling! And let's not forget the inventiveness and motivation. I was blown away to see vacuum tubes being built in a home workshop. Amazing, impressive and inspiring. Thanks for this video!

O! New glasslinger!

As an electrical engineer for many years and a Ham op for 50 years, this has been one of the most interesting and well done videos I have ever seen on KZread. You took very simple, mostly home-brew tools and built, not only a tube amp but a tube amp where you built your own tubes. Absolutely Brilliant !! Just curious if either of your parents, grandparents uncle or aunt may have been an engineer or technician and encouraged you earlier in life. WELL DONE !!!

Thank you! My grandfather was a radio ham and experimenter but I never met him. I have mostly discovered things through the internet and KZread in particular.

Absolutely amazing.. I've never seen someone make a vacuum tube from scratch. Loved it...

I recognized those Western Electric "chokes" instantly, they're the power supply transformers used to light Princess Phone dials. When the Ma Bell tech came around in the mid 1970s to wire modular RJ-11 style jacks in our home, he replaced ours, and gave me the old one as a toy. I made my first circuit with it, just hooking it up to a paper cone speaker to listen to the hum, or bounce a pair of dice around inside a funnel (a "random number generator").

That’s quite impressive, I’ve never seen anyone making their own vacuum tubes.

I understand some of the principles here however not all. The manufacturing of the tubes was absolutely awesome. The building of the filament and grid and the glass work and solder or welding of the grid and filaments which is obviously very tedious. Your many skills and knowledge of electronics and especially analog electronics Is absolutely amazing. This is the best demonstration of amplification I have ever seen. And to do it from scratch and with very basic tools. Your skill set and knowledge are absolutely stellar.

Just brilliant understanding of electronic. Just incredible job.

Wow that was freaking amazing to see! Watching you go from loose wires and glass pipes to pulling music out of the air was like witnessing actual sorcery. Awesome build!

This is why i love U-tube. This video is perfect. creating beautyful physics machines . the workflow and explanation is perfect. I feel confident I could replicate this work from this video,(with physical practice), but everything is here. I hope Ben Krasnow watches this.I love the sound of a dual stage rotary vacuum pump in the morning. You have an orange finned one and an edwards? beautiful, activating the getter with induction . The base reminds me of the flip flop i made from a ladybird book on electronics. Science and hammers , a pleasure to watch.

Amazing yet again!! Your tubes are looking prettier every time you make one! And they work well to boot! As someone who also dabbles in handmade glass tubes, I have to say I am very impressed with how far you've come and what you're able to do. It takes perseverance and skill to manipulate glass and make these tubes, and not a lot of people can say they are able. Keep up the great work! I look forward to seeing more projects!

Any good books on the subject? Ive built some tube amps and would like to learn the art of making tubes.

This is really beautiful workmanship. It’s wonderful to see technical projects done with aesthetic taste

I hope the generation behind me are watching this and learning, fantastic work. You are an inspiration.

Just ran across this, and it's so excellent. I'm loving the repurposed X-acto knife box as induction heater enclosure. Total mad scientist. Reminds me of me in my misspent youth. Awesome and super enjoyable. Thanks. nb: I'm kind of surprised the KZread copyright algorithm didn't nail this. Maybe the mains transformer core sat distortion is a good thing!
