That is one cooooooool looing tube Ron, that bandsaw and table saw look just about as old as that tube lol Gotta love old strong cast iron tools unlike today's flimsy BS,
You have so much skills and know how. You need to write a book before this knowledge is lost. Your glass blowing and vacuum tube building skills are few and far between these days. Thank you for sharing.
As an HND student apprentice with Ediswans back in the late 50's, I spent six months of each year at college, and the remainder in various company departments. One of these was 'Shrinkage Analysis', where failed valves and cathode ray tubes were examined to try to identify which production section was responsible for the fault. There was just one old chap there, helped by visiting apprentices like me, who plotted the results on charts pinned up in his office - but I never saw anyone from senior management take even the slightest notice of them. Your large transmitter valve brought back memories of occasionally sinking similar tubes which had gone 'soft' in tanks of paraffin in which was dissolved some fluorescent dye, and looking the next day under UV light to see if any internal areas glowed - indicating where the glass seals had failed. It was a much easier job with those giants than when examining the little run-of-the-mill B9A-based valves.
It’s awful how often much of the manufacturing knowledge and especially processing in material sciences is being lost, especially when we see how often proprietary knowledge even if the documentation for a specific development from r and d of a cathode coating process or a way to create a type of plate is always missing vital details that just aren’t sustained and this continues to be more and more of an issue… rch had the huge library of information and a few guys with the know how but like many ended up using a lot of old out of spec equipment and it just wasn’t sustainable or successful for whatever reason… it’s very strange to me that someone hasn’t taken processes used by Elrog and scaled them up, much like lundhal doesn’t rely only on ancient leesona 301 stick winders to make their Bobbinless cores to achieve the level of precision they do. I could be way off the mark but I feel like the environmental excuses seem a little strange.
I really appreciate your videos. Thanks for sharing your skills and knowledge. You are an inspiration for all people that love making and understand things
Could you fix this tube also? I can only hope something like this from you, I remember when you had to reopen the De Forest tube, but you still fixed it!
Great video thanks Ron,is there anything your not good at.You amaze me with your skills everything from glass work to electronics and wood work .You would be a handy neighbor to know and a great teacher I always look forward to your videos as it's great to learn something new even at my age of 50.stay healthy, regards
You are still a kid! Take it from me looking back from 77! Try to retire as soon as you possibly can! I managed to do it at 55 and life has never been so good! Good luck!
I'm 69 and if I'd have kept what I had given to me when I was young I'd be a millionaire now! Here in the UK we call tubes, valves, but we call CRT tubes, CRT tubes just like you do!
If the filament was somehow fixed and the envelope re-sealed, and evacuated, what one would use it for, a fancy light bulb? Unless you happen to have the Marconi transmitter it goes in. IMO given this valve rarity. probably best to keep it entirely original.
it looks like the kind of stuff we have in Rome, at the "Enrico Fermi Museum" inside the Physics Faculty of the "La Sapienza" University, with all the original laboratory and measuring instruments used by Fermi, Segre, Amaldi etc. from these pioneers of the atomic age.
This is what I like about your videos. When you restore vintage electronics you will fix the cabinet up as best you can. Other restorers will restore the electronics and leave the cabinet looking like a eye sore. lol I know this is not what you are doing here I'm just saying. Thank you for the video.
Say Ron: do ya'll think with your glass melting facility, er ability, do ya'll think yee could repair the filament and reload the tube with argon and display it under power?
Thank you for saving such large old transmitting power tube for others to see what was the cutting edge of the time , VERY NICE DISPLAY , ps love tube stuff
I suppose a high power LED mounted in back projecting light into the interior. Not much initiative to do it though. A lot of work for, well, no big deal.
That's incredible! They are extremely rare! This particular tube I have is special because it was actually used by Marconi in one of his transmitters at Glace Bay Canada. Marconi himself possibly handled the tube, examining how it failed.
Almost looks like one of those mercury rectifiers. There was a lot of odd stuff at Weird Stuff warehouse in Mountain View, CA. (Now defunct, inventory transferred to Gilroy down the road). Could someone post names/location of electronics scrap warehouses in California. I have a need to go browsing.
Ron, you have to keep that gigantic tube intact! There are legends that if you break all the vacuum devices in the whole world, the clouds will descend down. The grass will grow tall again the trees will become gigantic again and dinosaurs will appear again.
As always, an educational and fun video. Two questions though: What is in that brown case we always see on your woodworking bench, and if you had a hankering to, could you bust open that tube, put a new filament on, blow a new tube for it and make it work again?
Looks similar to the old RCR UV204 250W tube from the 1920's I'd think you'd be able to repair that tube with a new filament, but that would destroy it's value as an original. Instead of fly cutter, I'd probably have used a plunge router mounted on a hole cutting jig, or a hole saw. Problem with hole saws is they only come in a few sizes.
Sorry bout that. Question have you done a video on a small sterling tube tester. Only had 2 tube sockets. My mind is old. Thank you for your great videos ☺️ thank you.
I was wondering if u do repair work for viewers i have an old Sargent rayment that i would love to have it refurbish . Thank u from ca. Thank u for ur videos there great
Hi ron, Wondering if you could Just answer, Something for me, I mention I'm working on my first restoration, of a old tv, I just need to know Does Voltage carrie though The door knob capacitor, I have 430volts at bottom, and nothing going to My high voltage horizontal tube, from that wire, I know this sounds stupid, But I have never notice voltage going though capacitors, Thats why I,m asking.
DC will be blocked by the capacitor. First thing to do is replace all the tubular capacitors in the set. This will be necessary as they go bad with age. Yes, it's a lot of work!
@@glasslinger Thank you Ron for getting back so quickly,I have already replaced most capacitors except,for a few bumblebee capacitors, I tested all tubes and there good, Just not getting high voltage to horizontal tube, what do you think it could be.
@@glasslinger Hi Ron I know your a Busy man, But is there any chance you would have a 40's horozonal flyback transformer you would sell Me, My tv is RCA victor , I have been looking can't find one, Sorry about bothering you
He could fill it with neon etc and use a hf hv source to excite it but he said its quite a rare tube so cant see him doing that😅.. it's a shame its open filament, would like to have seen Ron run it.. I kicked over a GU39B the other day and I knew straight away it was finished and I was correct 🤦🏻♂️ the filaments are so fragile in those monster 13kw tubes 🤷♂️ I'm down to my last GU39B now and that's a worry as Russia is closed right now... I know I shouldn't have put it on the floor in the first place 🤦🏻♂️
nice find and nice job; by the way (forgive my total ignorance) ok, the filament is gone, but if you heated the cadode with an external laser beam, would that tube (theoretically) retrieve some functionality?
Unfortunately, the filament wire itself is the emissive cathode. It is broken and touching the grid inside the tube. At one time in the past there were companies that would cut open the tube and repair it. Expensive, but less than a new tube.
The glass used in the old tubes is different than modern glass. It is much more brittle and needs extreme annealing to keep it from cracking. Too much trouble to bother with. Modern tubes that will do MUCH better are available for about 50 bucks on ebay.

Holy crap, is there a tool you don't have? Great video
If he doesn't have it, he'll make it.
too bad you can't feed it juice and have it glow.. use it as a night light.. lol
Could you fix this tube also? I can only hope something like this from you, I remember when you had to reopen the De Forest tube, but you still fixed it!
I also thought, that the tube will be restored at first.
Ron, I was expecting you to repair this tube, you could have, if you'd wanted to, and we all know that.
I was ready to say the same thing! I'm sure he could replace that filament if he wanted.
if it was possible to replace the filament
Great video thanks Ron,is there anything your not good at.You amaze me with your skills everything from glass work to electronics and wood work .You would be a handy neighbor to know and a great teacher I always look forward to your videos as it's great to learn something new even at my age of 50.stay healthy, regards

Ron you don't think You could open it up, And fix it. I think you if anyone could ,You should Try Ron

IMO given this valve rarity. probably best to keep it entirely original.
@@michaelturner4457 I figured if anyone could build something to Transmitt that thing would be Ron, Just nice to see History work
The scratch on the plaque would annoy the hell out of me. The bad kernel spacing of some of the letters doesn't help either.
Gosh I almost thought that was a kenotron before seeing the part on the side
Could The Slinger Rebuild This ?

Nice tube Ron, great find and fitting use of it 👍👍👍👍

Very nice job. Now let's see you make one of these!!!
glasslinger could you do a video of making vintage style paper foil capacitors sealed in bees wax?
Its good that you use the term valve regarding a British vacuum valve
Como siempre, nos comparte excelentes trabajos.....gracias..
Hey that's a tube wow
I have a question for you.
This is what I like about your videos. When you restore vintage electronics you will fix the cabinet up as best you can. Other restorers will restore the electronics and leave the cabinet looking like a eye sore. lol I know this is not what you are doing here I'm just saying. Thank you for the video.
Also you may find interesting David Tipton's channel. He restores vintage radios and makes the cabinets look like new as well. Cheers.
You do such beautiful work and it's a pleasure to watch. Thank you for all these wonderful videos.
Amazing piece of history. Glad you found it and great job building display.
Your channel is underrated. You need subscribers like the giant retro tech channels.
I agree with Spilhouse with your knowledge please restore the tube to operating condition i would love to see that video
Hi again loves the vids :):)
J'adore regarder tes vidéos, je comprend jamais rien, ça fait au moins 10 que tu me fascine !
Merci pour ton travail, même si je ne le comprend pas =p
Glasslinger you are good at electronics and restoreing vintage shortwave radio Receivers
عمل رائع يعطيك العافيه
Say Ron: do ya'll think with your glass melting facility, er ability, do ya'll think yee could repair the filament and reload the tube with argon and display it under power?
I don't have the capability in my shop to work glass larger than 3 inches diameter. I would need a professional glass lathe.
Brilliant...
Thank you for saving such large old transmitting power tube for others to see what was the cutting edge of the time , VERY NICE DISPLAY , ps love tube stuff
The work that you do just blows me away 😀
I am the first
So Ron is there any way to make that tube glow?
I suppose a high power LED mounted in back projecting light into the interior. Not much initiative to do it though. A lot of work for, well, no big deal.
I have a dozen of the MT2, new ones, they look the same. They are beautiful monsters really.
That's incredible! They are extremely rare! This particular tube I have is special because it was actually used by Marconi in one of his transmitters at Glace Bay Canada. Marconi himself possibly handled the tube, examining how it failed.
Excellent work Ron 👍

I wonder what the power output of that valve is? I guess about 10 kW ? Thanks Ron for all your videos
awesome.
Looks similar to the old RCR UV204 250W tube from the 1920's
I'd think you'd be able to repair that tube with a new filament, but that would destroy it's value as an original.

That looks phenomenal!
You have the skill and equipment to replace that burnt out filament.😉
The mount though. Is impressive, maybe even more so than the Tube.

Hi Ron-how do you know where the tube came from? I thought you found it in the trash....
Thanks for the vise!
This one deserves a place of prominence in your living room (radio museum) Ron! Maybe on top of the Cleartone radio?

My Good, extrem rare vintage electron tube. Titanic for use transmiter Marconi.
Wow, we used to send them out for rebuilding just like one could do with old picture tubes.
Nice engraver you said ebay I have been looking at some but I never thought of ebay !
If it had a directly heated cathode maybe you could open it up and replace the filament. The filament would need pretty substantial wire though.
coooooooooooooool
Exceptionally nice display right down to the engraved plate.
It would be cool if it lighted up or used Corona lightning effects.
Beautiful mount for a beautiful tube! Amazing work as always!
Another great video, thanks from England 🇬🇧
great job Master, a greeting 👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻
The high voltage tube gets a place of honor. Nice job Ron.
Nice project. I like the way the router mounts to the table saw table.
you are rightly fascinated by Marconi
Glad to see you again sir , salutations from françe :=)
Nice tube. Would be cool if you could somehow install a neon bulb where the filament was and then it could light up when on display.
