oh to be able to do that, instead of trawling the internet to buy one. Most people would say 'let's make a sandwich' or lets make a shelf' not here, 'let's make a radio tube' such skill is enviable indeed.
Needed another tube or two to get it to work properly as a horn speaker amplifier. The journey was more important than the actually having it operate sufficiently. Thanks for sharing your build with us Ron!
I was holding my breath as you were sealing the tubes! Such a lot of work went into making those. Thank you for taking the time to show us. Very much appreciated.
mesmerising watching you build an amp from sctratch including making the valves . totally amazing watch. thankyou for posting such an interesting project
Simply wonderful!!! I am always fascinated with your technical ability, but more so with your creative mind. This world is a little bit better-off because you are here to share it with us!
I'm pretty much flabbergasted a person in a basement can do this.....35 years in the electronics field and this amazes me. I'm guessing only a handful of people can do this. Did you work for Westinghouse or some other tube manufacturer in the past ? Thoroughly enjoyed this !
Great glasswork, I'd like to see a geiger detector tube made, the fancier the better, would be very interesting, photonic induction (Andy) and big clive could make something with those tubes if there were a few as well 🙂 If there's any parts you'd like from the uk I can get them and send them over for you, any glass making tools or materials and I live 3 miles from a specialist miniature metal fabrication factory (laser cut, chemical etch, electroplating etc) so they can produce lots of very intricate small metal shapes and cuttings.. I can post things like that over in the mail 👍 Have a nice day there 👋
From the moment I discovered your videos years ago, up to and including now, you never cease to amaze me with your attention to detail, your craftsmanship, and your talent.
Been watching three years now and there just aren't words for your class of knowledge and skills. You should be sponsored by the Smithsonian and half a dozen other agencies and industries.
I may adapt your capacitive welder design to weld thermocouples. Did you make the welding jaws or just adapt some used ones? I had not realized how the grid spacing effects the operating voltage of the tube. That was the most interesting thing I learned from this video. Thank you for making your videos. They are unique and excellent, and I always learn by watching them.
I learnt my trade in the age of tubes and worked in QC at a Milliwatt / Mullard factory. I was taught that the pins connected to the inside elements via a small length of (i forget the name) metal that had the same coefficient of expansion as the glass envelope which prevents cracking. I am no spring chicken as you can guess and I take my hat off to you and your skills. Exceptional Best wishes from Australia
Cool videos dude. Keep it up. I absolutely love animals too. I’ve been at a place the last 2 years where I can’t have animals and it really makes you miss them. Every time I see a dog or cat I want to love on them. They are so special!
Hey Ron, lovely to see you post a video. Nice project, fascinating to watch your skills. Good to know you are well and busy. Nice to see the Supervisor is still keeping an eye on you. x
I really love your content, I think I would donate a € or two to your Paypal if that would help towards a better Camera. Not that the quality is not sufficient, but it would be nice to have a wider frame be able to fit more into the picture i guess. Love your Hair ! Keep going please and thanks for all the cool stuff you show ! 🙈
You have amazing talents! I love watching people work with glass, especially when you can combine electronics as well. Bravo! I'm curious how both sides of the lathe can be synchronized so well? ANY difference is speed or backlash in gearing and that tube's history.
Great job Ron! It seems to me that two tubes should provide more than enough gain. I wonder if the losses are from the interstage transformer? Maybe you could try a capacitively coupled design instead.
Who needs fictional wizards when we have a real life one to observe?! WOW, WOW, WOW! 😍 There are no words.... Magic, artistry, applied physics, engineering. 🧙
A glasslinger classic... incredible skills on display in electronics, glass blowing and carpentry, plus plenty of appearances from the supervisor, and all wrapped up with such warm self-deprecating humor... I look forward to your videos so much. Thank you!
Hi Ron, your craftmanship is amazing, years of experience - how on earth could your knowledge preserved for the future. You should think about employing an apprentice, not sure if you could stand one! Great video as always, good to have you back. Greetings from Germany
I believe that the stool that you set things on while you are varnishing your projects is going to last forever. After the nuclear conflict there will be cockroaches and your stool left.
Very cool! I had to stare at the schematic for a couple minutes, though. I’d forgotten that they used to send B+ through the speaker instead of using an output transformer.
Also I like the way you dress up in drag you are just too cute :-) and your dresses love it so cool and you make life look fun and im very impressed with your working skills that is like WoW i am very very impressed that s How all of America should be and get back to the drawing board and build stuff again yeah who needs China i don t .
Hi! Nice job. It sounds simple but is really hard to do. I'll make a 1920 amp... Ok first I build the tubes... Nothing strange.... So i learned a lots of technics in your videos. And I've seen a real cat wishker 😄 Ok I say goodby and send you best reggards!
“1920’s Horn Speaker Amplifier”. Oh good! I have some of those. Looks like Ron is going to show us one. “We’re making it, including the tubes by hand”. 😳 🤗 Didn’t see that coming! (I should have). I’m popping the popcorn!
A big surprise to see you making your own valves too! Fascinating! A definite art there in the glass blowing, then you have your different little spot welders & dual flame torches - totally new & intriguing. Terrific video thank you! Hey & what's your pussycats name? Give her a pat & a snort of catnip for me ok?
wonderful glass video... my favorite stuff and great electronics... be careful not to have a cat in the bottle/tube like a ship...Mmmm thanks a lot...:)
You could cheat and add a one transistor preamp to the crystal set. OR use the amp with a regenerative detector. Better ID for the labels, print them in mirror image onto photo paper in a laser printer. Then iron them on to the brass strips, the toner will transfer to the brass when the paper is peeled off under water.. Then spray with clear Kyron to protect the lettering. You can also use Brother P-Touch labels, black ink on clear tape.
Amazing, you would be sitting on the throne in the real post-apocalypse! The 'mu' was over a hundred, why did the gain not turn out enough to drive the loudspeaker? Was there another driver output transformer in the horn unit or is it 'high impedance'? I watched the guy bending wires and stuff at the Radio Museum in London 30 years ago, didn't see the glass work. He was making the bulb shaped style.
