Thanks. An enjoyable trip back to my 11 year old self in 1960. I used to make and sell xtal sets to my friends

Two 6.0 Volt tubes and a crystal diode AM radio. The tricky part is making the Lexan tube socket stand and components on it. Neat job there Ron. Circuit shown at 40:43 in video. Fun watching you build this radio! Needs a 1N34A cleverly hidden under the crystal. I won't tell anyone!

Oh how the memories from over 70 years ago were stirred by this video. Waggling the cats whisker using the red plastic knob on my Ivalek crystal set to try to get a signal, which would only be heard if I happened to be tuned to a station, so it was 'wiggle and tune' together until a sound was heard in my ex-RAF headphones. Then my fingers would twitch, the non-linear connection would be lost, and the process had to be started again. When someone showed me a germanium diode for the first time I couldn't understand how something so small, with no knobs to twiddle, could work. But it did - and what a wonderful innovation it was!

It's 2am and I stayed up much later than I should have, but watching you build a Cats-Whisker valve radio from scratch was compulsive viewing. That is a work of art Ron.

I love it when there’s another video of yours up!

Havent seen a glasslinger video in quite some time....... EXCELLENT!!

That’s a beautiful work of art! The diode is a whole lot better than trying to tune a station off a rusty razor blade.

Been dying for more of the basics. I could watch basic tank circuit radio stuff all day.

I remember as a kid my dad bringing home a pair of old headphones and an old variable capacitor and telling me about Crystal sets. My dad knew nothing about electronics, but I got a book from the library about making Crystal sets, and I wound a coil on a card tube from the inside of a toilet roll, saved up pocket money to buy other parts like the OA91 diode and wired things up as per the book, wrapping a piece of wire around the cold water pipe and stringing a length of wire out of my bedroom window down the garden. Amazingly, I could hear radio stations in the headphones. This nailed my future in stone as to what I would do later in life!

Good job my friend! our little secret 😂

Fascinating discussion on the type of wire in the coil. I did NOT know any of that! Thanks for sharing your expertise, Ron.

An interesting build and fine looking vintage receiver. Thanks for sharing. Well done...David

Nice job my friend. Always a nice treat to see a new video.

Vintage mica caps and Allen Bradley carbon resistors make this radio a period authentic reproduction. Nice work !!

I also have a home made crystal receiver from this period; but without an amplifier stage. you did good job 👍

"If I had any common sense, I would have measured it..." This is why I like watching your videos. You're the opposite of a youtube sperg. These are the people who think because you own a torque wrench, every single fastener you ever touch should be torqued to "specs" they just made up or are generic to the fastener size. They are joyless. They are also the type of people who pretend, through editing, that they never make any mistakes.

When I built genuine galena crystal radios as a kid, I found that washing the chunk of galena in soap and water, then rinsing in alcohol made the surface much more sensitive and easier to find a "hot spot".

Ron, you amaze me every time with your skills to create anything. When i was a kid, i made a crude crystal set, a toilet roll tube to wind wire around for the coil. a 500pf variable capacitor, a diode, and an old telephone ear piece. The antenna was a long wire, and i gave it a copper rod earth. It was so loud,, Radio luxemburg was very clear indeed. Great fun :-D

Ron your Just amazing, You where born to do This,

Really enjoyed! Didn't expect your doing this from scratch ... wonderful Ron, . Such a clever guy. thank you

What a great video. Considering the era of the tubes you used, I suggest that an additional but related project could be a single battery power supply. That would be the type using a mechanical vibrator booster circuit. You probably remember those in portable and car radios. The vibrator was about the size of a vacuum tube and made a low hum.

I'm so glad you are making one of these

This just makes you imagine how excited the original designers were when they first heard signal coming through.

Used to play a round like that on a peg board as a kid. It never looked that good. But it helped me get a job in telecoms.

Thanks Ron! It was interesting see You fiddle with the cat's whisker, showing it's not that easy. It's the first time I ever seen this in practise. I think Your solution was brilliant (I promise not to tell).

I decovered crystal radio a couple years ago and have had a great time doing different types. I ran across 100 in 1 electronic project kit and built and hooked up the amplifier to the crystal and it was very nice. A lot louder then I thought it would be.

Great vid!! I’ve been winding coils for crystal radios on Quaker Oats boxes. I apply a few coats of lacquer to “stiffen” the box a little bit, before winding the coil. There are much better coil forms, but using a Quaker box adds a bit of nostalgia…..and it is what I have on hand. I teach science classes for home schoolers and the kids get a kick out of making one. No whisker….just a germanium diode. Cheers es 73!

What fun! I love this video. It reminds me of the old days when I used to build Heathkit stuff, but you do it from scratch!

@18:00 Thanks for explaining the litz wire principle, I never knew. Very helpful. 🎈

Now i know why my grandfather went on one if someone touched his whisker, great content - stay safe

Amazing..I just love watching you make all sorts of radios values just keep the video coming. Please

Amazing how you build from scratch such "period correct" masterpieces!

Great video...I remember trying to make a crystal radio as a kid in the 50's using a blued razor blade and pencil lead . Had the same kind of problem you found

Ron has the tools, the knowledge and the skills. He also has courage and great taste in fashion. I have nothing but admiration!

At 42:40 -- that was the best radio circuit description I have ever heard. For once I sorta understood what was going on. Thank you so much.

👍🏼. Thank You Sir/Madam…. Your videos are just outstanding! I was watching with my grandson and he hasn’t stopped with the harassment…. “WHEN ARE *WE* STARTING THE RADIO PROJECT BUILD?” 😳 Now, I’m kinda stuck . But I’ll be enjoying every second!! Your knowledge and skills are just amazing. Thanks for keeping vacuum tube technology alive! BUT….. PLEASE BE CAREFUL WITH OIL …. THE GE X-RAY VIDEO FRIGHTENED THE HELL OUT OF ME. WATCH OUT FOR PCB CONTAMINATION . Thanks again.

That 1960's gogo dancer mini dress was fabulous! Get in a cage and dance!

That was the best description I’ve heard for Litz wire.

Great work and at the same time practical and accurate. I have followed you since you started your KZfaq channel and learned a lot and a lot. I live in North Africa and I do not have the capabilities to work with. this field, thank you

I've always thought about building; that project, but with transistors. Perhaps I will. Thanks for the video and have a great week.

Loved it! Looks great. Thank you Ron.

Great video! Always good to see you. (Miss Kitty Too) :-)

You remind me of a guy that built outlaw linear amplifiers for CB radios back in the seventies. We would go on parts scavenging raids to the local salvage store mostly searching for transformers and whatnot. He built me a 160 watt amp that was clear and powerful. Those were the good old days!

What a pleasure to see somebody use their brain to safely use power tools instead of a heap of gadgets that just get in the way.

People who could find the active area of diode way back, were worth their weight in gold

судя по умению обращаться с инструментом и по наличию оборудования высокого класса эта уважаемая дама серьёзный специалист в радио электронике. процесс изготовления наглядного пособия ( детекторный приёмник на кристалле сернокислого свинца )напомнил мне моё детство 1958 год, мой первый радиоприёмник.

I really enjoyed your unpretentious down to earth discussion. So much more enjoyable to listen to.

Stop everything ! Ron has a new video

The tip must be very sharp and the contact pressure must be very low for the diode effect to appear. When I was a child, I periodically tried to sharpen the tip, and then very quickly I could find a "sensitive" point and listen some music. My father, who was literally making transistors for his PhD thesis, advised me this way. At college, 12 years later, I learned why the contact region must be very small. Point contact theory is no longer taught, but it was interesting.

Хорошая катушка индуктивности и отличный конденсатор ! )) 73

Was a fun project - congratulations - you sure know your stuff too. Thanks for the voyage back in time.

I thought all along that you found a way to amplify a crystal radio without using an external source of power. I was astonished because it didn't seem possible. Then, I hear the words 'now let's turn on the power - click.' I was thinking dooohhhh. I've always been fascinated with crystal radios since I got my first one from radio shack. My friend at school put it together for me and i enjoyed it for months until the headphone broke. Cheap plastic crap from radio shack. A replacement radio came with a pre-broken headset, then I was out of allowance money. The thought of receiving information without the use of electricity beyond the written word is fascinating. It's almost like magic. Later, when I was in the navy, we utilized sound-powered headphones to communicate between different watch stations and the bridge. It was a no-fail system that worked regardless of the power state of the ship. Same concept. Just fascinating. After watching this video, I found an actual site that claims you can use a supercapacitor to store power from the radio as it's tuned from a strong station. Once the capacitor is full, it could be used to amplify a crystal radio for a few hours. Not sure it works but it's a fascinating concept.

Multumesc mult dm, m-am distrat privinduva si citind comentariile Frumos si educativ ptru cei ce vor sa invete tanele radio Da astea sint primii pasi in practica dar fara o pregatire serioasa si o intelegere profunda a multor cunostinte teoretice nu va reusi nimeni Prin urmare indrumarea catre cei ce doresc asta, sa dobindeasca mai intii cunostinte teoretice si sa le si inteleaga

Ron, you DO have a soldering IORN after all! None of that gun stuff! 🤣 Just messing, what a great video, a pleasure to watch! Thank you

Sweet a good Sunday vid :):) Thanks

That’s a beautiful work of art! Thanks for posting.

Hi Ron your tech friend Dave here another amazing video how you professionally built that Crystal radio you're very good at what you do I always enjoy your videos you're the best in the business may God bless you and keep you safe always your friend Dave

The tools, the skill, the safety, the experience........... Beautiful.

Dang that is cool. Using 6au6. Oh the point contact diode. Old school. 😷😍keep up the great work

Thanks Ron,what a great build

Glasslinger you are good at electronics restoration of radios receivers and shortwave radio Receivers

Well made. Always in a good mood. Thanks.

Thank you for sharing. I really loved watching your work come to life.

Your videos are amazing! Thanks for sharing.

Always good to see you building something Ron!

Great stuff as usual. I just love this early radio technology and I am also developing a fondness of 'dark walnut' stain.

Glad i took the time for this video! Everytime i'm in awe for your solid skills - just spot on.

I used to use Galena (PbS) and works all the time. Maybe the pin wasn't fastened tight or not sharp enough. Great work I must say. I showed my grandson how one can get sound from a piece of rock.... and he was amazed. Hope I can make him build his own radio one day.

Wow, great. Bult some sort of receiver based on this design myself in the 70' was lots of fun.

This is a very educational video. Great job!

This is a truly amazing and wonderful video! Wow! Very nicely done - thank you for presenting.

Awesome Ron!

This was very enjoyable thank you for posting!

thanks Ron... really great job... enjoyed this one as always...

You build custom radios. I loved the radio radio. You do great work

Thank you so much for your work on this. I always learn a bunch from you!

It is very relaxing and very fulfilling to watch you work.

enjoyed the build thanks, you look experienced at the circuity!!!

At least its am and not FM I remember making one with a radio shack kit as a kid some 50 years ago. Its funny as far as electronics has evolved over the years this is very basic and above most younger peoples heads. You retained all what you learned. Thats cool

A great job, it looks as good as it sounds.

Awesome job. That would be a cool daily driver.

Thanks. Another great creative video.

Great, Ron, and mum's the word regarding the fitting of the diode in place of the crystal...ye-he.

A work of art. great video as allways.

What a great thing to do at the end of the weekend watching a great video.

Your radio making and repairs are very good

Glass linger you are good at restoring vintage shortwave receivers and alignment of vintage shortwave receivers my friend 😊😊😊

Great video. Great craftmanship!

This is beyond awesome, also for the longest I never realized how they got baseboards to have that specific curved edge until now

That's beautiful, and voltage is still friendly.

I once had a piece of galena and made a crystal set with catswhisker adjustment. Very difficult to get working until I cheated and used the stripped end of stranded wire as a brush. Far easier to get going. Back when people were using crystal sets with amplifers for radio reception the tubes would have been triodes much like the tubes you make in your workshop. The type of pentodes you are using in this amplifier date from at least twenty years later than when this type of radio was in common use.

Well done there ,your a star.

As Wile E. Coyote once said….”Super Genius!”. That’s you, Glasslinger!

I really enjoyed your video I've been trying to learn Electronics vintage electronics I found this video very helpful thank you I enjoyed it

Beautiful and well explained!

Very nice radio Ron. 👍

Phenomenal craftsmanship.

Basically the variable cap on the antenna is an antenna tuner which in more modern tuning caps is built into them as an adjustment on the back. Your setup is more of a direct adjustable attenuation setup where you have the ability to adjust the signal attenuation rather than it being preset to a central point of the band.

I love it. Great job!

That table saw looks like my antique Craftsman that my grandfather gave me.
