RESTORING AN ATWATER KENT MODEL 35
Вставка
- Опубліковано 9 чер 2020
- This session we will restore an Atwater Kent model 35 radio which was an early battery set from about 1924. It was sometimes called the "loaf of bread" radio because of it's similar shape to a loaf of bread. It is a 3 circuit TRF with detector and two stage amplifier so it easily drives a horn speaker. The tuned circuits on this set are mechanically ganged together to make it much easier to tune than the 3 dial versions.

Ron, Could you do a video of yourself? Your background , how you got started , Where you learned to do what you do? I find you to be a very interesting person and would love to hear your story.
Yes!!!!
Would love to know a bit more about your background.
Please make a video to introduce your gorgeous collection!
Gorgeous collection of radios or dresses? I'd watch both!
Glasslinger, one thing that makes you stand out from the others is your ability to laugh in the face of setbacks... and sometimes, even laugh at yourself. Please don't lose sight of that. Every single one of your videos is a gift. I look forward to your next one.
This guy is an absolute legend just love his videos and could watch his videos all day.
UA-cam legend
Don't be too hard on yourself! Your "damned incompetence" allowed us mere mortals to see what is in that little secretive power supply box you have there. Next should be a video on it.
I don't know why but I suddenly have a taste for strawberries!
Great job again Ron!
I find your videos very relaxing and entertaining. I thing part of it has to do with the soothing background noise from you air condition or fan!
Ron I"m absolutely in love with you power supply. Is there any chance you could possibly make a video and show us how it works and how you made it? Thanks For all you do.
This one turned out to be a terrible mess inside. I will remake it some time using a cleaner design and then share it. This mess is not reproducible.
Another fantastic job Ron. You are spoiling us with all these fine videos in June!
ive been watching this mans work for 8 mounths , he the best ive ever seen
I can remember my grandfather finding those AK radios at the dump. Back in the day the dump was always on fire. One time while picking the dump with my grandfather I found an old wooden bushel basket filled with WD-11 tubes., all burnt up bases. I managed to save a few and rebase, and tested good, but 10-15 were ruined. I miss those days “picking the dump”, and shooting rats with my grandfather. Today’s youth have only video games to keep them busy.
Aaah, the smell of rosin while soldering... that´s paradise :) When I was a kid (living in poor Poland at that time), we used that for soldering. Brings back childhood memories. I can smell it while watching, no shit! :-D
The smell in an old radio factory must have been lovely with people assembling the radios using rosin flux
Your channel is an American treasure. Thank you.
At 18.53 your voice sent a shiver down my spine. It sent me back 40 years when I was an apprentice. Close my eyes and I could see my supervisor TOTAL INCOMPETENCE SIZMUR I'd run a 30kw high frequency dialectic wielding generator with out a dummy load .still remember as if it was yesterday
You kill me Ron! :) I too can get rather ridiculously upset working on these sets. I always say to myself "the radio Gods are angry!" when that unique screw falls and you kill 20 minutes searching on your knees - if you ever do find it at all! Those metal AK's are so homely that I love them for just that! I never had the chance to acquire a decent working one. They always need to have the cans opened. They look great with the large "spare-tire" cone speakers. You have to love any and all AK's. Good job by the way. Stain on the metal! Very good! I have to remember that one.
I really like your power supply I have been making some power supplies for a little while now
Please don’t be so hard on yourself you have great skills and appreciate your videos
loved all your videos, I`ve been watching for about 4 years now, Well done Ron as always
Most of us salivate over that power supply, Ron! Keep those gem videos coming..............
I've learned a lot from you. Thanks for sharing your knowledge and experience.
Thank you so much for your videos that teach me how to fix these beautiful objects.
Ron don’t beat yourself up over a few loose screws. It’s never good to do angry repairs it makes for mistakes . Your normally such a jolly young man take care and Thanks for sharing best regards chris
I yell at myself for doing dumb-ass things myself, the neighbours think I am utterly mad, welcome to the team.
The tie posts we get these days (the cheap ones) are utter crap, the soft plastic threads strip so easy.
Radio's running nicely :D
Cheers Ron,
Another wonderful job done! Thanks for sharing.
you're kinder to yourself than I am to myself when it comes to "personal, losery incompetence" ! I relate Ron, when I'm yelling at myself I'm often called a "jackass" ! ( :
Many thanks Ron for another great vid...
Geez, I thought I was the only one freaking out on myself like that!! 😂
Still, wish I had a quarter of your skills my friend.
Ron you never did a half ass job in your life - keep an eye on your blood pressure though, I cant see a video for the power supply you use, a circuit would be interesting and useful, many thanks - Stay Safe
Those power supply connectors has always been troublesome, they need double nuts and Loctite but they will always get loose over the time.
I've learned so much from you ron, thank you and keep on keeping on! Nick, isle of man in uk
This video is gold! Could you show us that power supply? And it would be interesting to see your radio collection too. Nice job Rob!
Thanks for uploading! 🙂 let's have more of these wonderful videos and old sets 👏
Don't be so harsh on yourself Ron ,You do a fantastic job ,you should see the mishaps i self do in my workshop wire things up backwards.On a better note Ron please pass the strawberry's they look Yum.
Another great video, thanks Ron!
you spoil us! so many new restorations to watch. thank you. btw you can't use strawberries as capacitors...
One of the best radio seen neat n clean design three gangs
I had a mentor who would get pissed off when test gear and basics weren't all there. He taught me to stop and be very concerned until I knew I had what I needed... saved me from MANY problems. Earlier today actually.
Hello , je suis Français, Super votre vidéo , ce sont mes préférer les TSF Batteries , suite a une de vos vidéos je me suis fabriqué la même alimentation, il m'arrive parfois aussi de remplacé le circuit de régulation !!!!! vraiment Génial Merci
Much better than those 14 part boring restoration videos. Quick and dirty.
Another thing that happens to these radios is that the bands ganging the tuning capacitors break because the wheels on each tuning capacitor experience oxidation cracking and grow. This phenomenon is due to poor metallurgical consistency of the pot metal. I think that these radios were not made until 1925 and ran to 1927 and was the first radio to have a stamped steel case. Atwater Kent had previous experience making auto parts and was used to such methods. The model 35 had a huge production run of 1.6 million.
That Rider manual volume looks like the technological equivalent of a Magician's Grimoire; a real treasure indeed. I'd love a workshop like yours but I lack the knowledge or skill to justify it. Fair play for working on yet another classic radio! I'd hate to see these beautiful machines get discarded when they're still usable, would be too much history lost.
Always a pleasure to watch
Thank you Ron. This skill is becoming and art - and even in my days no longer taught in engineering school... these are great videos
Great content! Thank you! 💜💜💜
I dunno mr Ron.....I almost want to ask if you would allow a strange but very respectable and honorable husband and wife pair of visitors to visit your shop. We are so amazed at your video collection....and also amazed with you yourself as well! You make wanting to come visit you as fun as if going to Washington DC and the museums! Hell, I’ll even force my wife to bring along a few summer things or a frock or two along with us for me to ware while there!...when in Rome, and all.....you know! So that I will fit in with a
Screwdriver in one hand to join in the radio fun! 🤪
You are owsome, l love you work.
Happens to me all the time. I have to fix the thing that i need to fix what i'm working on. Thanks for the videos.
Hello and welcome to Tantrum Corner... :)
I use violin resin
just dissolve it isopropanol
and cheap and great working flux
Wow, superhetrodying only requires one tuning knob, local oscillator tracked the tuning circuits at 455 KHz above, so, so-call intermediate fixed frequencies could be used, even broad tuned for expanded bandwidth.
In my neck of the woods, only two AM stations near by, and when the sun goes down, so does the transmission, but still can listen to a lot of static.
So this will give you something to do after the sun goes down. Another good use of this is for a winter space heater.
Ron, this was a very interesting video! Will you give us a class on the grid leak resistors? How they are manufactured, how & why they fail (along with carbon breaking), why 20 megohms "is too much," etc.
Also, can these old transformers be repaired/rebuilt? Can you go into doing that too in the future?
So, the "modern" rosin-core solder doesn't really have rosin in it? It really has a "modern" substitute? I don't recall my solder having a pine tree scent. I wish I understood how real pine rosin-based flux works -- I think it would be neat to be able to make some. :)
I think you need to keep a small jar of short pieces of wire for hooking your bench power supply to these really old radios. It would save cutting & scraping pieces each time you work on a radio.
Will you explain that horn speaker and how it works and is adjusted?
Thank you for talking about how the CRC Brake Clean is a polar material that won't affect the paint that's on this radio. Are all paints non-polar and this brake cleaner safe on them?
Is that housing a Bakelite-type material (with the bottom being sheet metal)?
Please show us your Atwater-Kent Bread Board radio!
Sorry for all of the comments/questions, but a lot of them popped into my mind as I watched this. And, I'm jealous of your strawberries too. Now we'll have to pick some up the next time we go to the grocery store. ;) Take care!
You said you got into radios in early 90s I was born in 90' you probably started when I was born 30 years is a long time love these consistent videos lately.. also what happened to the supervisor haven't seen him lately..
Splendid Ron! Maybe a matte finish would look nicer? Then again I would not know how it looked new. ...
I’ve never seen a pair of slip grips that small before? They are tiny!
I bought a pair of small grips a while ago but they’re not that small. They’re actually really handy as you can do so much more with them than having a big pair (That’s what she said). But then they are electricians grips (CK 🇩🇪) so, yeaaaa.
I love Germans and UK tools as they are some of the best in the world. I’ve bought a few electronics bits from Japan in the past and I can truthfully say, that they are some of if not theee best hand tools in the world!
I would love to get some hand tools but I think I’ll need to sell my arm as I’ve already lost a leg 🦿😜
good work!
I had the same problem with my power supply, loose nuts on the plugs, so I understand your frustration. (-:
I always tend to make my boxes too small so by the last rebuild I decided to make the box big enough to be able to manage the wiring.
The trick for those banana sockets is to put the lock washer between the panel and the socket, not under the nut.
You might never want to do it but I would love a house tour of your house because I saw on one episode where you were cleaning stuff at your sink and that was a beautiful old sink that you had and I have a sink just like that sitting in our bar and that I’m going to use in my own place someday when I have my own home because I just love older date at homes or homes that are built to look like they were built back in the 1800s atleast to the 1950s
What better than vintage rosin used to repair a vintage radio? Thanks for sharing all your knowledge.
great work , i do the same thing when i have done something silly :)
THANK YOU RON FOR ANOTHER GREAT VIDEO. 73 KI7DYM MAL
Ron ! you on da blob again ? Radio sounds hifi . LOL But On A Serious Note, Please Keep up The Good Work and Thanks For Taking The Time To Make These Videos. I'm A Big Fan. Gary From The UK
Don't be too hard on yourself, doing goofy stuff and feeling dumb about it is everyone'd bane. Thanks for the video
For the same price, this video is a fix of two devices : a crappy home made power supply with authentic unscrews plugs, and a beautiful radio ;)
Splendid for the viewer...
Wow, in the UK I don't see any kind of electrical equipment much older than 30 years. I agree with Keepitlow, seeing your collection and more history would be great. Also, wooden capacitors??? I have never seen the like.
One question, what are the sometimes large coils wound round very beautifil coils? Are they air inductors?
Love the chanel.
Ron, your videos are great! Is there any way I can make my tube radio more sensitive while living in an apartment?
Ron I'm missing the tube making videos! Please more glasswork!
We love Ron !
🍓 nice video 🍓
Good to know with solder gun..need to get one.
It is not a Pain, It is a Adventure..
Damn you. Now I want strawberries....
Thx. ❤️
An external power supply to achieve all necessary individual driving conditions for the tubes of a radio?! Wow! Was hanging out to see the circuits beneath the tubes where one would expect them to be and then obviously all control circuits are inside a wooden box! Its not a prehistoric car radio by any chance?
Restoring an AK Model 35. Have clean brass pulleys and two perfect copper belts. Any info on tuning alignment would be greatly appreciated!
The external design is utilitarian
10:15 - Well, rosin comes from pines so that's no surprise, lol.
wish i knew what he forgot,,great work
Ron, could I implore you to please share the schematic for your battery eliminator power supply ? I’d like to replicate it.....
I could see myself when you started to get angry with yourself over the PSU.
Why didn't you take the knobs off prior to lacquering? Great video as always, thanks Ron!
'01's are still relatively affordable compared with #10 or #46 ($50+ each). 50c5's are getting high too. All the common numbers that everyone used are harder to find.
Dammit, why did you have to have those strawberries there!? Now I want strawberries, and I've got non at home! :)
Otherwise: great job as usual! :)
Where did you find this diamond? You have a lot of rare radio models
how come it just sat there so long?
here in england its summer, so naturally it is raining heavily! ha
ive found if it is humid using lacquer stops it drying clear and it turns white, is there a way to undo that?
Warm and time usually the cloudiness goes away.
Just rebuilt an AK 37.
To tin the wires, I lightly sanded first.
I restore valve radios in the U.K. I have never seen that style of Grid leak resistor does anyone know if these glass resistor were ever used in the UK ?
Yes they were and were just as unreliable. mullard.org/search?page=1&q=resistor&type=product
100 year old ready?? Sounds great. Find a radio or tv built in the last 30 years that will be around nother 20? Very hard to do.
I thought Ron was going to blow a gasket. If this had been my dad the radio would have been smashed. Ron started this radio business in the 90's? What did he do before work for Raytheon?
hi Ron, how can I repaint the case with the same effect ?The original paint is damaged.
p.s. I miss the kitten
0:33 - Even rarer in this shot: The elusive Stromberry-Carlson!
Hey I have one of these. Can I test power it without that fancy power supply you have? All the tubes are there and it has headphones with it. I was expecting to be able to use regular house single phase power, then looked at the input. Is it DC powered? Can I use batteries or AC? Is it like a CB radio? Assuming AM radio?
The radio requires 5 volts at 2 amps DC to run the filaments, and 45 volts DC at 50 ma to run the tubes. The voltages do not have to be regulated but should be well filtered.
It would be nice if you explain you power supply
What to do with the unworking tubes do you try to repair the filaments or other problems or throw away?
Go in the donate box. There are people that collect duds. I save them up and give them away.
I saw a project in elementary electronics sometime in 1988 that used a false tube that did not work or wasn't used but had hidden electronics. The transistor crystal set work by that. It made no sense to me but each project are their own.
I was told that some early tube radios used the mains cord as a voltage dropper and was cut to length depending on the drop required. Have you heard of this before?
AKA the "curtain burner"! :)
Resistance wire. It's a fact.
Hello, could you please pass the electrical connection diagram that you have for the description of the video? I am one of your followers, they are very good videos, the ones you make, I would be very pleased if you pass that diagram that appears on the sheet that is shown in the video. thank you very much in advance keep making more videos since there are few people left who like antiques especially radios it's like they take us back to the time in which they worked
Any Galena radio?
Ого, балует!
Ever tried a 112a in place of a 71a?
They seem the same to me. I don't have the manual handy but there must be something different than the number I would guess!
as john wayne said - as rooster cogburn about mattie ross - (s)"he reminds me of me!"
Is it repairable if I don't have any strawberries handy?
Hmmm. Possible.... But unlikely!
I would tight the nuts and paint them.seems like paint stop everything from coming loose. Or use glue or something.
Ron... my friend we all make mistakes..
Especially when filaments we're hot some easy breakage. Took some years off maybe.
What's a modern replacement for a grid lead?
It’s just actually a carbon resistor... the modern replacement would be just a regular 1/4-watt resistor but think of how out of place it would look... Some restorers will rebuild the old style by drilling them out and adding a modern resistor inside where it can’t be seen... Not exactly sure what you would do with the glass resistors for a rebuilt though...
@@budandbean1 Thanks for the info! I was looking more into it, and is it actually called a "grid leak"?
