That is awesome! So great to see it working! Thanks for making this. It's the first time I've seen a handmade magnetron.

Great Job GL!

Professor Ron is just pure magic....

I am so pleased that the people here recognize what you have done. In 1940 the magnetron was literally the most important thing in the world, and all the best brains in the UK and USA were working on it. You have done similar work in your own workshop. Bravo Ron!

That’s awesome thanks for building a working version! It amazes me how well that works with the tolerances and how it was built! Crazy to think in just a few years they went from a few milliwatts to kilowatts and even megawatts! Thanks for all the cool stuff you build I don’t know of anyone else building vacuum tubes other then Nixie tubes on KZfaq!

Very interesting indeed. Obviously if a manufacturer can make them, a person with the correct knowledge and needed equipment, can as well. You just proved that. Thumbs Up!

Very nice to see this one oscillate! I was so disappointed when the seal failed on the 1st one, I thought I might have to make my own to see a split anode magnetron work. Might be fun to make some kind of transceiver with it, or maybe just Lecher line demo with a neon bulb detector.

I wonder how many people can make a home made magnetron. Your unique,,, you know you should tell your story, where did you get such a vast array of skills & experience unmatched here on KZfaq

I watched quite a few of your videos years ago (6+) and thought I had lost your channel forever. When I saw this video being recommended to me I noticed the name and it clicked with me that it was you. Your early videos influenced me greatly in my pursuit of knowledge in electronics and building complex things in general. I will make sure subscribe this time, I hope you continue to upload entertaining and educational videos.

Thank you Ron for showing us a completed and working version. Really appreciate you sharing your knowledge and time with us, it's a real joy to what your videos. Thank you!

Very cool demonstration with the lamp! I've seen RF light up gas discharge lamps plenty of times, but that had to be inducing a lot of current to light up an incandescent bulb!

I'm sitting here with my mouth open. I think you are the only one on youtube who knows how to do this.

Brilliant :-) In this video you looks like the real Emmett Brown :-)

I have learnt more about tubes from glasslingers videos than trough my entire studies and career. Excellent material, so greatful for this very special entertainment. Keep going!!!

I did'nt knew the modern magnetrons made from metal had predecessors or that one can make a magnetron from glass. Thanks for trying again, great success ✌️

Congrats on making a working one, I admire your perseverance.

This is beyond amazing!!! This takes electron tube making to the next level. Very few people have the electronics and glass blowing skills to accomplish this project. Thanks again Ron! Please keep the videos coming.

Who would downvote this? You remind me of my dad, Bell Labs man, making all kinds of stuff in his shop. Nice work - food for the mind.

fantastic work ron , thank you so for making the second version

You are a wizard! When I studied physics at Goettingen, one of our old professors was himself a student of Max Born. He used tell the story that Born did not want to become an experimental physicist because he had absolutely no hand for glass blowing ;-)

Growing up I read about this stuff (amazing stuff!) but never knew how it's made, if you research how it's made unless you go to college you hit mostly dead ends. I am so glad youtube is here for people to share things of how it looks, is made, and, works. Knowledge is one of the beauties of life thank you ~SUBSCRIBED!

Thumbs down for what? Absolutely amazing. I suggested if you gave him a thumbs down you build your own and show it off.

If first you don't succeed!? That's really something. I'm glad it turned out. :)

Thank you for sticking with this project.

you have a gift. glad you're still interested in providing the internet with all this information! :)

You are a real treasure with your videos. Truly some of the most versatile talents I've ever seen!

It is such a pleasure seeing you make these thermionic valves!

watching this again....Surely the deepest font of technical know-how on KZfaq. Just love these. I very rarely learn anything from any other technical channel - was gonna mention names but not necessary... Here it is something quite, quite different. Full of wonderful knowledge. great entertainment and fun and I always take something away from Glasslinger.

Just found your channel a few days ago.. excellent interesting and informative videos..waving a hand from Bluff City Tennessee.

you do really cool brainy stuff with the attitude of someone showing how to sharpen a mower blade...always awesome thank you

Very informative you'd make a great electrical engineer teacher.. Taking apart microwave oven magnetrons I never knew what the ferrite wound inductors were for. You just taught me that the capacitance of the cathode and the inductance of the inductors set the resonant frequency. Amazing stuff. 350 MHz is blazing fast for a homemade magnetron. Nice job making it work and thanks for the share/lesson, Martin.

Thanks Ron, very informative and fun to watch. Appreciate your sharing your skills.

WooHoo! Fascinating video, congrats on getting it working! I like your channel, because you're about the only person I've ever seen build a magnetron just for kicks.

Absolutely fascinating! So much better to watch this than the crap on tv

Thanks for the conclusion on this. I was really disappointed on the conclusion of building it, but not nearly as much as you must have been!

Awesome! Glad you took the time to make it again.

This is just great, that it lamp working! Hey, can you make a simple Geiger-Muller tube ?

You do the coolest projects, you knowledge is just amazing.

That's quite an achievement, congratulations Ron!

Outstanding work by Ron would we expect anything less I think not thanks for posting this ron

hi Ron glad you got it working (i knew you would) i love the home made valve videos.

Hurrah! Awesome job

Very cool to see it working!

Does it matter whether you flash the getters or seal the tube first?

You are the legend, well done Ron.

Ron, we all knew you could do it. Stil amazed by your knowledge.

I LOVE your video's - Incredibly interesting and totally mesmerizing. Thank you so much for the time you put into these :)

You should be very proud. You think it, You do it, We love it! Outstanding! Thank You. from Mr Bill.

Well done Ron, brilliant. All the best.

Homemade radar - the next please! )) Shocked. Deeply impressed. Keep going on!

I think you're amazing and wonderful to watch - Thanks so much for making this video.

Glad to see the final results! Excellent work.

Greats from Holland, its awesome to watch smart people. Its magnetische energie and the torusfield. Im still learning every day thank you for making this..

I'm glad you gave it another shot. Congratulations!

Ron, you should remove the magnet to demonstrate that it is a magnetron.Without the magnet the oscillator stops

Try again and it was a success! Excellent work.

Can you explain how a travelling wave tube works or even better that and try to make a TWT?

You just wipe out all the rader in a 10 mile radius....Iv been watch your work for the last few mouth.and your knowledge is grate.keep making the videos

Brilliant! Waiting ... Oh, you just had the pickup right there, haha! Let's see ... confirmed! Awesome!

Awesome! Well done! Imagine how jealous you could've made the 1920s/1930s tube makers!

That's is incredible. It takes a tremendous amount of skill to make it work.

Greetings from Italy Sir, I absolutely love your videos. Ad Maiora!

Nice one ron, i knew you could do it, your skills are on another level.

next thing we know youll be making a mini nuclear reactor and you should be called the mad scienctist love watching your experiments and making these things

That was great thanks for posting! I suspect it was transmitting a bit more power than it may have appeared to be putting out as the light bulb circuit had a high impedance mismatch. 600 VDC @ 8 ma is 75k ohm load from the power supply and the output circuit to the lamp circuit appears high in impedance. It would be interesting to build an output resonant circuit with a match to 50 ohms and feed it into a UHF/VHF watt meter with high power 50 ohm load. By achieving a good SWR match this tube may be able to operate at a much higher voltage and power as the arcing may be due to High SWR's in the circuit.

I knew you would achieve it, well done :) If there were an award for KZfaq creator’s best creativity (fanfare sounding) - you would win first prize.

Always worth watching. Thanks.

Wow, very impressive. Job well done ! Loved to see how it actually looks while flashing the getter inside of a tube :D Best regards,

Wonderful you are so talented it's amazing to watch your videos i have watched them all thank you for posting

Congratulations! Well done!

Thank you for your work!

All your videos are excellent, thank you.

Fantastic ! So interesting to watch - Many thanks.

can you do AM by using an electromagnet?

Awesome, thank you for completing project :D

Try feeding the HT to the anodes via a choke so that the RF isn't going up into the HT PSU. You may well find that the output or bulb lights a lot brighter because you are not losing RF in to the power supply.

What an amazing freakin' mind, to even think of the projects he does. Never mind the skill set needed to do all he does. It would take most more than one lifetime to learn even half of it all!

Fantastic!

Fantastic Mr. Science! 👍😄

Totally fantastic, as always. I really appreciate being able to see a skilled craftsman. Oh, I see someone suggested a travelling wave tube (TWT) below/above for your next project. If you want an even more difficult project a photomultiplier tube (PMT) might be a head scratcher. Although, it would be difficult to show that it worked in a video, unless it was low number of stages, and that kind of reduces its usefullness. It would take some creativity to show it in operation, without damaging the PMT due to too much light causing it to self destruct. Anyhow thank you as always, and take the suggestion, as just that I'm sure you have your own ideas.

Another tube video! Great work!

Well done Ron, no one can do what you do,,, best

congratz on the success! fun little project --Rick

Ron, you made my hair stand on end and I'm in England. No, not the megnetron, that would be silly. How many people on KZfaq can do what you do ? None. That's rather worrying, the skills and knowledge you have are rare, quite unique. The videos you make are a lot more important than you may think. I have never seen anything like them in over 70 years. Don't stop Ron.

Amazing engineering talents! I'd be proud to have half yours. Quoting John Aaron's NASA flight controller colleagues after he saved the abort of Apollo 12, and later helped Apollo 13 return, "you sir, are a steely-eyed missile man" (sorry, I'm not sure which pronoun you prefer - but in my view that is the ultimate engineering compliment!)

Awesome skills making the toobs 😁❤🤓

What fun! Thanks for sharing.

Very nice! Congratulations!

Amazing work ! 👍😃

Awesome! Cool to see it working.

Tesla called it " total loss broadcasting " what an awesome demonstration , I am smoked by this great defenestration .

So awesome, keep up the great videos!!

amazing!!! and the field strenght meter is really showing something at (i guess) 1 meter, but i'm asking myself... can it light up a small fluorescent tube?

Excellent content Ron - ATB

Thanks YT algorithm. Another great channel I wouldn't have found otherwise.

You are a badass. Thank you so much for posting your knowledge. I love your content. Piece and love

Wow! Loved that.

Brilliant Stuff Earthling

Outstanding! As usual...

I like your videos! They are practical. I feel like I can do it.
