Mr. Carlson, I wouldn't have used the battery cover to leverage the wind-up piece. I'd be afraid of breaking it. Just saying.
Hi where do you buy your electronic components,
This needs a part 2 where you show us how you repair the battery holder, on/off switch, and ferrite antenna.
I agree! I did not fully enjoy this repair video because watching the fix is part of the fun. Too much time spent looking at the schematic. Although I still love watching Mr Carlson work his magic.
the ferrite antenna is an easy fix you can pick up replacement ferrite rods off of amazon
"Hey look, we've got some rules! [...] 'Be careful not to damage or remove the plastic cover' [...] That sounds like an invitation to remove this plastic cover!... okay [...] we'll do that, because that's just in the rules." 😆
This is one of the coolest mechanisms I've ever seen. Just the idea to come up with it and then to get the green light to go ahead and build it and then another green light to go ahead and sell it would never happen today. Thank you Paul
To judge by the last couple episodes, Mr. Carlson really seems to be getting into these new-fangled transfer-resistor things!
Paul has blessed us with these videos lately!
Mr. Carlson IS a blessing!
very cool indeed. Looks like a great candidate for a restore/fix up (switch/ferrite rod/case dent/battery holder/clean). Great to see the alignment process as well. Cheers.
Never seen that clockwork auto tune system before, very neat idea
Electronics is my first love. I used to do a lot of board level repair on all types of printers, computers, monitors, power supplies, even hard drives. The thrill of chasing the problem. It's really very rewarding when you find and fix problems that few can and you sir, are a master at it. Thanks for sharing!
Please keep making these transistor radio restoration videos . So cool !
Awesome Mr C., it's a true pleasure watching you work a schematic, a true art in and of itself. This was a very unique radio, never seen one before. I suppose this jewel will adorn the museum shelf after a few minor fixes, a rare find I'm guessing. Great video as always, as usual I learn from every episode. Thanks and 73.
Even after all the work you put into the lab, it's plain to see you love what you do and this in turn makes it a joy to watch, listen and learn from you....Thanks!
I appreciate that!
Now that is a neat auto-tune mechanism, very unusual design and totally unexpected. I think it's worth a restore on that merit alone. 👍
@ 4:15 -- The viewer at this point scratches his head and wonders why Mr. Carlson doesn't break out his ultra flexible, 3-D rendering boroscope invention that enables Mr. C. to walk through the innards of the radio with VR goggles...
Very Fun video on a Panasonic Radio. Panasonic made some cool stuff of the early 70s. Never knew this radio existed. Thanks Mr. Carlson.
That's a cool mix of clockwork and radio. A very interesting find.
Perfect Sunday night viewing. Thanks from the UK 👍
I have been a long time watcher and wanted to share some exciting news! I have found my first radio for restoration, it is a Northern Electric Model 5000. Was picked up at my local electronics recycling center for the low low price of free! Super excited to follow along with some of your videos and dig in!
You should definitelly dump those leak-a-cell Duracells....
"Dura Leak" . . . It is sad the direction they took. I was always an avid user of Duracell in the 1970s and 1980s, but it seems Energizer has Duracell beat for not leaking (and destroying the electronic item) far before its time.
Enjoyed this video - learn something each time I watch one of your teardown . Thanks
When you said the radio had a hand crank, I was thinking of a radio that was being given to Missionaries in South America. This so anyone in the jungle if no power could listen to HCJB and TWR, Trans World Radio on the island of Bonaire,( I was an TX operator). The radios were powered by a hand cranked mechanism.
The radio you’ve got is a really cool radio! I’ve never seen one of those.

Always fun watching you troubleshoot unusual vintage electronics Paul.
That was an hour so well spent thanks Paul
Unique example of an evolutionary branch of portable electronic entertainment. Electromechanical solutions that work, but the "DNA" has evolved to modern life.
I remember the solid chunk as the TV was adjusted by the clicker.
Nice saga as always.
Ah, the satistifying clunk of tuning VHF TV. UHF could be fun too, but not as clunky; more tiresome really, if the station you wanted was halfway round the dial.
I remember the first TV we had with a remote control. It was a Zenith floor console with a fancy keypad with LED (or VFD?) display that used an ultrasonic remote (the battery kind, not the one with tuning forks). My young ears could clearly hear the high-pitched squeals as you pressed the buttons - the cats could also, much to their dismay.
what a super cool radio Paul... great job and I love that "Star Trek" dial! Also thinking that a DC motor, in addition to being electrically noisy, would also put extra drain on the batteries.
That orange strip should be on the inside of the batteries. You pull on it to get the batteries out.
Thank God you were here to let us all know! I mean the man is only the foremost electronics genius on youtube, as capable an electronics engineer as ever was. Of course he didn't know what the orange strip is for...sheesh 🙄
What???You ever believed this genius man is ignorant of that piece of orange strip😅
@@francisMbizaree
A genius is a person who understands that he still has things to learn.
Spring powered Auto-Tuning. How cool is that...
Thanks for teaching us poor folk something useful, I really appreciate the time and effort you put into sharing your knowledge. You're like the uncle I never had.
Thanks Paul, one of your best videos, full of interesting observations and useful information on this clever radio.
Many thanks!
looks like bots in comments! love your content mr carlson, always learning something new
Thanks!
I have to agree with you regarding the old Tek 'scopes , Paul. I was introduced to them in 1970 at my first duty station, Naval Security Group Activity, Kamiseya, Japan. I Immediately fell in love with those 'scopes.
I didn’t know that Panasonic made an auto tune portable radio!
Very cool!
I get the vibe that we don’t even completely know just how amazing you very much are. Just my intuition, let’s call it. Thanks for all the fun videos to watch, or even just listen to. Great stuff!
Thank You for your kind comment!
Thanks for the great video. What a neat little radio! I've never seen one auto tune like that.
You're welcome!
Great tear down and circuit explanation. Thanks !
Glad you enjoyed it!
Very cool. Thanks, Paul!
Great view of innovation and troubeshooting, thanks
Thanks Paul, big thumbs up!
I also find the high frequency analog scopes useful to find clipping when voice is in place on RF transmission. Not for the spurious RF per say... But for if there is any thing up from the audio chain that can lead to spurious radiation. And they are defiantly quiet!
Yes, nice demonstration of auto tuning. Automatic tuning and station presets have always been a feature of "better" radios since the late twenties. This is about the 1960s and a beautifully simple drive.
Thanks!
Thanks for the O-scope work, it's always my favorite.
You are an amazing man, nicely done sir!
That radio is really cool. Very interesting to see how the circuit works. It reminds me of the 1950s "Wonder Bar" radio I had in one my first cars which, when you pushed the button, would seek stations and stop on them just like this radio... (though you didn't have to wind it up). It also had a foot switch on the floor board so you could amaze and baffle your friends by changing the radio station using 'magic'. I always wondered how the wonder bar worked... and now I know. I also like the way the tuning condenser just rotates endlessly, up the dial, down the dial and up the dial again forever.... very cool.
My dad's car had that. It was a Buick.
Superb video! More thanks from the UK!
Excellent demonstration and that radio is just amazing! Hello from Ontario Canada.
Very well aligned and logically presented explanation. Thank you!
People The Reason why we use Analog scopes even today is because A DMM Or a Digi Scope can lead you up the garden path when you want to go down it... Even today 2024 When I Test Longitudinals copper we Use analog Low Ohm ... You can end up in a world of Hurt if you are Not Careful. Spot On Mr C as Always ..... Legend Ham Operator ..
Thanks Paul for your great videos. Nice to see transistors for a change. Maybe in a few years you’ll move on to IC’s 😀.
You may find this video interesting then: th-cam.com/video/37lIpTxUQcE/w-d-xo.html
Thank you so much for this video. I really enjoyed watching!
I found over the yrs butter knives are great for getting apart things with claws, tabs etc.
LFOD !
Cool radio.
An absolute pain though if you're listening to it with an earpeice and you have the radio in your pocket. That button would get pressed a lot. LOL
This little radio is so interesting. I love the auto tuning mechanism!
Mr Carlsons lab you are good at restoring antique radios and alignment of antique radios my friend
Haven't seen one of these before Paul, great video - Thank You !
super well done🎉
Another great video lesson. I do appreciate the radio repair videos
Thank you Mr. Carlson! 🔈🔉🔊
Great video in somewhat new "rough" style, im here for any MCL videos but this was just +++. Now im hoping to find this type of radio with FM... Thanks for a perfect schematics walk through, im still amazed how much stuff you know. Thanks from a Swedish Patreon.
Glad you enjoyed it!
You deserve many more subscribers, thank you!
Your videos are always great. This was a very fascinating radio and loved the way you troubleshoot the problem and tuned it! Thank you.🙂
I like all your videos and I always wait for you to bring a new one. Thanks Paul.
That was a really interesting one Paul. Very well explained. Thank you
Never saw a radio like this before. So glad you took the time to work on it for us viewers. Interesting!
I couldn't have resisted taking care of that battery box and switch first. But The Master has no worry for those trivialities.
Paul, I just love it when you find these rarely seen radios and fix them. Just for fun I did a search for one a few minutes ago and discovered an Ebay listing that had sold 6 hours before. Thank you for providing wonderful content and education!
My pleasure!
The similarity of troubleshooting circuitry to troubleshooting the flow of a software application always amazes me. Electronic logic gates vs mechanical logic gates. Graphic symbols vs function descriptions. Identify the general problem, verify, fix, test; repeat until done. Despite that, my eyes glaze over in a minute.
First Panasonic I ever saw with a wind up mech....cool!
Awesome ! never seen a mechanical scan like this....cheers.
Clever arrangement with a continuous tuning cap which scans up and then down the frequencies whilst always rotating the same direction.
Great back to basics video Paul!
Yes, please do more Solid-state repairs
Sweet a new long video! I really enjoy the long videos.
@MrCarlsonsLab thanks for the great work you do, and the way you explain things
My pleasure!
Thanks for the knowledge
That was fun. I like these alignment videos.
I have the AM/FM version of this set. Works very well.
Simply amazing how any one can hold batteries in place, jumper a defective power switch then trouble shoot and align the IF circuits. AND make video of it!!!!!!
I built my first transistor superhet radio when I was about 16 years old and not from a kit. I had to etch the PCB. This auto-tuning radio is fascinating. Thanks for showing us what it can do!
Fun video Paul. Interesting to see the mechanical and electronic design that went into the radio. Pretty amazing to see the sensitivity of the radio and your troubleshooting and alignment procedures.
I have one of these receivers somewhere in storage, Thanks 4 this!
I enjoy these wonderful radio repairs. Also, the Gilligan's Island Style Radio Packard Bell AR-851 is an interesting radio. 🤔 Thanks for the great troubleshooting video.
New content, my day just got better, thanks Mr. Carlson. Long day teaching young lad.
My pleasure
I love this little radio! I hope you continue fixing it up. ^_^
Circa 1965 radio, I believe. Thanks for the video!
Excellent. I do R/C stuff and was pondering the escapement servo and reed receivers just today, but I'm anything radio related and to see this Radar Matic video as well, kinda got me thinking I need more gears in my life.
Thumbs up,another machine that I've never heard of or seen, great video
Hi. Very nice receiver ! And you're the best !
Paul excellent repair on getting this radio working and it is the neatest Panasonic portable Radio I have ever seen. They use to have signal seeking car radios that did the same thing in the 1950s & '60s.
Mr Carlsons lab your antique panasonic radar matic Am transistor radio is awesome my friend
Paul one of the best videos you have made very informative on alignments really got something out of this. Thanks Mike
Glad you enjoyed it!
This really was most amazing thing in 1968. Unfortunately in Finland there were exactly one radio channel worth listening, unless you knew Swedish or Russian.
It would be interesting to see the operation of this receiver in the open air, away from industrial noise and city interference. A very interesting radio product)).
Mr Carlsons lab your TH-cam videos are awesome my friend
Reminds me of my 1938 RCA console that has presets. It of course has an electric motor that tracks back and forth the dial, but it mutes the audio until those preset stations are located. Great video sir. Enjoyed it very much.😊
That was fun...thanks!
Super!
It's been a very pleasant trend for you to work on smaller, affordable transistor radios. I always felt a bit diminished when you repaired those wonderful, museum condition tube console radios. I can relate to transistor radios as they are affordable to me.
I actually had one of these for several years, and it worked quite well. I sold it about a year ago. I was constantly freaked out by the manual tuning. I always held my breath when pushing in and tuning that wheel...kept waiting for it to break.(I have anxieties, haha).
You are a real gift in your calm demeanor and incredible knowledge. Appreciate it....
One of the things I liked to do was to just look at the circuitry and figure things out. Some of the old tuning mechanisms are close to being works of art with the springs and cables tuning inductors that track with the tuning cap. Thanks for the education!
Awesome as Always Really cool vid Thankyou
Great explanation on the tear down 👍….So clever how they get around the auto tuning using what was available at the time.
Thanks 👍
