I noticed at 1:10:15 that you are trying to peak the sensitivity and you have to really concentrate during turning the tuning screws. It helps a lot with tuning or fine adjusting such screws when you temporalily mount a large diameter knob or "wheel" to the other end of the adjusting screwdriver. Thus you can control the angle of the tuned screw more precisely since you don't focus on the gripping of the tool. It will also reduce the shakiness of turning something. We are humans are good at gripping and putting torque, but for extended times it puts strain on our muscles and tendons. Thus the fine control ability is reduced over matter of seconds.
what a wonderful video and a classy little radio. nice to see the process covered in a single video.
VIM ???
Question Mr Carlson - I noticed that the Shortwave Antenna and Oscillator coils not only have different amounts of turns; but also seem to have different gauges of wire. Does the wire gauge also affect detecting and receiving the different bands?
Thank you for your many years of high quality, indepth instructional videos.

The harmonious relationship between manufacturers and customers back then was fantastic. Sad to see what it's devolved to today.

For those who did not know, Northern Electric became Northern Telecom in the 70's and then Nortel in 1996. The company was based in Montréal back then. Very nice radio. Thanks!
I buddy of mine worked for a smaller telecom that got acquired by Nortel. He had so many stock options that he made a $1 million after the acquisition. He was smart nad invested in real estate. Talk about being at the right company at the right time!
I attended multiple Northern Training centers and worked on Nortel PBX's and Norstar systems for about 30 years. Their "No Forklift" upgrade was something of a joke as you sometimes replaced a card cage but not the entire PBX. It was great stuff and years ahead of much of the Bell System equipment. I retired in 2006 and Nortel was gone just 3 years later with it's assets sold to a number of companies..
That is kind of what I was thinking although I had no idea about the years. Is it still a Canadian based company? It is hard to tell anymore with so many companies buying out other companies.
@@brucewinningham4959 my understanding is that Nortel went bankrupt in 2013 (the largest bankruptcy in Canadian history at that time) after allegations of Chinese Military/ corporate espionage that benefited Chinese telecom giant Huawei.
Good to know Bertrand! Thanks!
Your level of knowledge blows my mind! You jump right into stuff that most people would shy away from, (like fixing an audio transformer with wires not much bigger that a human hair!). When you opened up this box, I thought, "I wouldn't know where to start", but you made this radio a thing of beauty! Thanks for sharing!
Those Canadians sure knew how to build a radio. The workmanship on that 5 pack is beautiful. The workmanship of the restorer isn't too bad either.
I just completed watching this video, and while I don't always watch every video you do, I almost always tend to watch the restorations you do on antique/vintage radios etc..
Many many years ago, (back in the dark ages! Lol)) I worked in a TV repair shop. We of course also did radios and other electronics as well. I' really dating myself, but it was way back when things in the TV repair business were really changing quickly. Think early through mid 1980's especially. Long before internet and flat screen TV's, but things were changing very fast at that time. Most of the high quality name brands by that time, meant nothing because those names had been purchased by Chinese companies. So even though people thought they had bought a high end "beautiful Zenith" set, you'd find when you opened it up, it had the same, inexpensive Chinese "guts" in it as the no name brands. So, they had just started putting the high end name brands on inexpensive Chinese junk at that time. As for the electronics, Chips were just starting to get more and more common., as to where before that time we rarely saw any "chips" at all.
What was nice about that time period was that it was before things really changed into the throw away world of today. People were still repairing things whenever possible, instead of just throwing out and replacing. But with the Chinese name brand scenario I mentioned above, prices of sets were coming down quickly and the throw away world was approaching quickly. But at that time, there was still a lot if the really high quality brands out there, being brought in for repair. (Of course we'd go to the house and repair there if a simple job, but most often sets were brought back to the shop... LOTS of carrying of heavy sets in those days!) But in the early 80's, we were still taking in for repair MANY sets made in the early to late 60's. We were still replacing picture tubes etc. So, it was a great time IMO. This was also before people had cable tv in their homes. So, tv tuners were still being used. Many sets were still manual, no remote control. Or, some had the original 'Clicker' sent in with them. Remember those! Lol ... Tuner cleaner was still the #1 spray we had on the bench. And the old Zenith rotary dial tuners, with gold contacts that we'd strip from the old sets to collect the gold from. Lol Those old rotary tuners would get so dirty, and of course cigarette smoke and nicotine was absolutely caked up inside coating all the sets electronics! (Since everyone still smoked in those days) But yea, those rotary Zenith tuners you could coat with Tuner cleaner, and then go to town just spinning them like crazy and most often that alone would clean them up. Vertical & horizontal output transistors, audio output etc etc. Lots came in with the common problems of those days.
Long story short, I enjoyed those years a lot. And am happy I was involved at the time I was. My life went a different direction some years later and my TV repair days were over, except for an occasional home project on an antique radio or something just for fun.
Your love of electronics shines through your videos and in the quality and details of your work! Obviously it's a labor of love for you, and it's that quality that makes people GREAT at what they do. Your work is excellent, and you address every detail in your restorations. And again, if you didn't love these old pieces you're working on, and didn't love the electronics inside of them the way you obviously do, that would change everything, because as I said, your love & enjoyment of what you're doing pours right out this end as we watch you!
Thanks for sharing your passion with us, and thanks for restoring all these beautiful old radios you work on. It's great to see them functioning as new again. Sadly, with these great old pieces of our history disappearing, its almost like losing part of Americana as we've always known it. And while I don't think we'll ever start manufacturing TV sets and radios in the US again like we used to, we have these ild sets to restore and to show the younger generations the kind of quality and items we used to manufacture right here in the USA. And that was back when if it said 'Japan' on the back, we knew it was no good and into the trash it went! Lol in exchange for an American made set. But how the world and our country has changed. But that's another topic not to discuss here.
Thanks again for all you do! 'JM'
Thanks for your kind comments, and taking the time to write "JM." That was a great read.
As a young teenager we had a 6volt battery unit that I was occasionally permitted to take to bed for DX listening. I had an exercise book that I would record station call signs in. I would turn into a broadcast and stay until a station I.D. was broadcast. Date and time recorded I would re-tune and start the whole process. I was later introduced to radio repair and repaired, re-built many older receivers. Thank you for letting me re-live those memories.
Mr Carlsons you are good at electronics and restoring vintage shortwave receivers and alignment of vintage shortwave receivers
I always love your restoration videos. For me this one was different because you included your cleaning process as well - really good to see that. It must be so satisfying to listen to these sets after you have restored them.
That transformer repair was EPIC! Surgeon precision. I am so glad you showed that. That is a tough thing to do right. 😃
Another wonderful restoration. So lovely to see these old beauties brought back to life.
I beg to differ. Any idiot can take an already working radio and recap it
Good tip about the open output transformer broken wire. I always thought if open it's toast!
Thank you for some 1949 memories, sitting outside with my dad into the wee hours of a summer night while he searched the AM broadcast band.
Love these "full length" restoration videos, complete with the Q-tip cleaning process. I imagined a little Curious Mark elevator music during this cleaning and disassembly section. Oh, and I'll tip one back later for the, "If you're following along at home..." disclaimer! (Hi Bob!) :D Thanks for another fine video, Paul.
Mr. Carlson, It would be awesome to see you design and build your own custom vacuum tube radio using your extensive knowledge in radio electronics! I bet it would work amazingly well!
A fine restoration! I have this same model. It was a gift from my Canadian friend from Montreal. I'm a "cap-stuffer," so I stuff both the electros and paper caps.
My radio was originally ivory.. My friend stripped the cabinet and polished it, then presented it to me with ivory knobs...I liked the brown cabinet, so I left it as-is. In a short while, my other Canadian radio-buddy from Ottawa, was looking for a set of ivory knobs for his (original paint) Champ, so we traded mine for his original brown ones. A win-win!
After a complete alignment, I was _amazed_ with the sensitivity of this AA5 radio as compared to many others of its ilk! My guess is the quality (Q) of the inductors. Cheers!
Mr C. Best of both worlds, top side you have given homage to the original designers, yet Improved the under chassis layout. Best of both worlds.
Mrister Carlsons lab your antique Baby champ tube shortwave radio from 1946 is awesome my friend
Nothing like doing a little "knob-twirling" on a classic 1940's radio. Wonderful job as always Professor Carlson !!
A first rate presentation and addictive viewing. I shall watch them all.
Your radio restorations are so elegant and thoroughly done! Thanks for sharing this. Have a great day!
Mr Carlson, what I found impressive is the way you did the proper back and forth alignment to get the local oscillator to track to the dial. The correct way to get an AM or SW radio aligned.
Timestamp ~36:00... thanks for showing us HOW to clean away grime on the metal chasis. And the minimal narration was appreciated (helped me concentrate on what you were doing).
I always enjoy watching Mr Carlson work his magic and restore old radios. I wish they were time machines and could receive stations from their time. Of course if they did, I am not sure if I would be excited or freaked out. LOL
Hi Paul this is Dave Wallace/wally .With self tapes .When you reinsert them you turn them backwards so they click then you turn them forward so they cut in on the same cut✂️ as before this will stop stippling of the original . material . If you have this problem You use a bit of copper wire to space out and this will save you. Have done this many times and have had great results. Great show/channel 👍 .Best wishes 10/4 Good Buddy.
I 💕 love these old radio restorations the older the better 😊🇨🇦
Thanks for sharing that alignment adventure.Slow and complete, it seems to stick.
You're welcome!
The best am/sw alignment video I’ve ever seen and I’ve seen a lot of them.
Antique Dust and Over spray. Authentic Dead Bugs. 😂😂 Leave no pot unturned! Thanks for the Content as always !
I graduated from technical school in 1995 ( analog/ digital electronics PC's and peripherals and industrial electronics) and always wanted to do what your doing with the troubleshooting and repair. Your video had my undivided attention from the start. Awesome stuff.
Great job as always! I especially liked the repair of the transformer. That radio is so cool, with the pointer that looks like a little propeller and the dial face that looks like an aeronautical instrument.
It's always a great feeling when you bring something back to life. Great job 👏
THANK YOU for not cutting out the tedious nature of aligning it. So many instructors would have done a few quick cuts and shown it all peaked up, leaving us wondering why it took so long to do on our test benches when the video showed it done in a jiffy. Also, major points for mentioning a Theremin!
Glad you enjoyed Justin!
Love that front face design! 👍👍👍
I have this EXACT radio. Paying *very* close attention to this one!
The in-line fuse. Absoultely the best takeaway for me, moving forward. Thanks.
Looking forward to this one. Thanks Mr Carlson
I was a bit proud to read, on the back panel, that this nice radio was ''made in Canada'', more particularly in Montreal. We've had a long history of well made electronic products that is mostly forgotten and/or ignored. Thanks for restauring all these meaningful radios, amps, that America created and that brought so much to our well being. Sylvain Qc
Nice to see this restoration ,its realy interesting to follow the finetuning off this radio. Thanks 😃
I have been enamored of these art deco radios as long as i can remember. I currentl own a Sterwart Warner table set from 1947. It remains idle since it does not receive any stations. I absolutely do not doubt it was a solid performer. I turned it on once! What a beauty all lit up. It works at getting started, but alas state of AM broadcasts is non existent. Yet i could tell the sound was spectacular. Its a beauty. Keeping it! He's all mine, lol.....❤
In the late 1970's I was taking electronics classes at my high school and we made our own circuit boards. It's was always fun to build and make things work. I think it's a big mistake that schools have taken out all of the shops from both the junior and high schools. Thanks for the information, Mike
Mr. Carlson, I want to commend you for an excellently presented, on what I consider a mysterious subject! Although I’ve always thought that electrical devices, radios, receivers, speaker etc. to be fascinating I never thought I could understand the deep intricacy of the parts, tubes, coils, transistors, capacitors, resisters etc. and design of the radio despite having always been a very analytical person. You obviously have that very deep knowledge and understanding of those electrical devices. That coupled with your excellent communication skills makes your segments content easy to follow without getting bored even after a video of over an hour and a half long. Thank you for such an enjoyable channel to watch and listen to.
Bloody Good Elucidation! I'm inspired to hack my way through the jungle of tube radios propagating in my shack!
Another excellent video. So nice to see these old radios come back to life.
Another great restoration plus the transformer repair. Can't wait for the AR88 restoration, I have one waiting here and will be following along
Great video Paul, definitely my favorite format....from dusk till dawn. We get to see almost all of it in one go. It seems you can do these restorations with one hand....the amount and quality of knowledge you have is amazing. Can't wait for the next one. Cheers everyone and peace.
Thanks for your kind comment Nelson!
MR Carson's I should Have none , You have a reason for everything You do, Your are Amazing, Great work sir.
Your knowledge of electronics and electronic theory is inspirational. I truly appreciate your channel and the knowledge that comes from it.
Ive learned loads just by watching this, this is brilliant paul.
Wow you extracted fantastic performance from that little 'all American 5' in every way possible! An extremely thorough presentation, thank you.
Aww "Baby Champ" what a cutie! She sounds incredible!
Engrossing! I admire your thoroughness and eye for detail.
Your alignment procedure brought back memories of convergence procedures for my Heathkit Color TV back in the late '60's! I was younger then and with more patience.
I really appreciate how well you explain the background information and the repair philosophy you present!!
To get stuck knobs off, I use string wrapped a few times around the shaft behind the knob and gently pull. To clean bakeline, T-Cut metallic and a soft cotton cloth does wonders.
Always my favorites are the restorations. I hope to own one someday.
Thank you for showing us how you repaired the audio transformer! I was glued to the screen while you were digging into it and finding the broken wire.
That was fun, thank you for sharing.
I keep returning to THE LAB. And see what Paul has ON THE SLAB.
Superb job! Thanks for showing the details on how you repaired the transformer. You made a clinic out of getting the itty bitty wire soldered back up and stationary with some strain relief and packaged up nicely. I guess since it won’t be moving/bending back and forth anymore it’s safe from braking.
I so enjoy watching Dr. Carlson at work. His knowledge and expertise are beyond description. His pace is very relaxing. Keep up the good work Dr. Carlson!
I always whack my signal generator onto the primary side of the audio output transformer and if I get a tone from the speaker it's done, of course the radio is totally disconnected from the mains and is one of my first cold tests I do. I love the long video repair format that you do it's your channels best output in my opinion. Fantastic restoration video Mr Carlson.👍👍👍
Art Deco radio brought back to it's glory. Thanks.
Brilliant diagnosis on the audio output transformer 😀 👍
WOW! That looks like you just bought it today. Beautiful condition.
I've done dozens of radio repairs, but still learn new things here.
Thanks for your feedback Tom.
Sir I KNOW this is off topic but it must be done. I send you a BIG heart felt THANK YOU for your hard work on this channel. I collect vintage 1970's era HIFI audio equipment. Receivers, tape decks, equalizers, expanders and more. Thanks to you I know a LOT more about whats happening under the hood in vintage electronic gear. I know what capacitors, resistors and relays are and how they look when distressed or broken. I can't detect all bad by looks alone BUT I've learned how to spot bad repair work and so much more. I've learned to spot easily fixed expensive but broken gear offered cheap. I've literally saved 1000's using what you teach here.
How absolutely marvelous. I never got beyond Heathkit and Eico but watching this video is intriguing and stimulating. Thank you for such a fine effort.
Very nice video, I was given one just like yours but only with AM which I restored and have the same sensitivity results as you do. Thanks for sharing such an extensive restoration video.
Perry, Sherbrooke, Qc.
what a lovely part of history. Great job on the restore. Someone will love this old radio. :)
I love to see sets resurrectted like this, you get the feeling its lost on the throwaway modern day youth culture. But i just love this!
This radio is 2 years older than me. I wish I looked that good! 😉
Beautiful job Paul. I am really looking forward to the grand receiver restoration. Thanks so much.
Beautiful work with the audio transformer. Would love a radio like this for AM talk radio.
Once again Paul, I learned a lot about so many facets of restoration including cleaning and the products you use..I learn so much by watching step by step..
It is so satisfying watching and listening to a technical perfectionist! Thanks, Paul! 👍
Glad you enjoyed it!
Great video, Mr Carlson! I have one of these from my "collecting days" when I first moved Canada. It is my favourite receiver and sounds (for it size) absolutely amazing! It fills up the entire bottom floor of my house with wonderful sounding AM signals. And yes, the shortwave capability is amazing. Thanks for sharing this!
You're welcome Thomas!
Very helpful information and detail on this process...thanks, Paul! I imagine the listening demonstration was with the 3-6-9 antenna; works great. Thanks for sharing.
Thanks for taking the time to put this video together and posting it here on CZcams....An amazing trip back in time to 1946 radio and the inner design of these fantastic old time radio receivers.....
I always use a polarized plug when replacing power cords .
To keep chassis neutral and the hot side switched.
Your videos are the best Stuff I have found for electronic repair and restoration
Thanks for your kind feedback Gerry!
I always ad a small isolation transformer for safety , security and perdormance.
Mr. Carlson. I want to be just like you when I grow up.
Paul,
I like the PIP action, thanks.
AA5s can really perform when they are carefully designed and with a couple of extra refinements. It's a simple design that is easy to manufacture, easy to repair, and they just flat out work.
Thank you for fixing a radio that was born when I was. Some kids in my neighborhood used to fix radios.
That's such a lovely piece! Thanks so much for giving it a new lease on life!
Thank you for showing us how you clean the chassis. I think this is the first time you've shown this. Very instructive!
That is a beautiful object.
At this point in time I couldn't be prouder to be Canadian. Thanks huge lad.
Sorry, could not listen to the end because I was drwn to my radio so I could listen to those DX signal also. Thanks for remembering me why I am a ham, 73!
Looks and sounds great, Paul! I really like the in-depth format as it really augments my limited knowledge of antique electronics and electronics in general. You've given me the confidence to tackle some of these projects on my own and I've so far been quite successful. I just wish I had your talent in acquiring the spectacular subjects you work on! Looking forward to the next full restoration!
Thanks for your kind feedback!
Dear Mr. Carlson, I truly appreciate your knowledge and expertise, I learned so much and am very grateful to you.
That was a really good and thorough video on radio receiver restoration. Unbelievable how well it performs. Thanks for sharing.
Thanks again for sharing Paul.
I love this particular radio! I used to collect them, but only knew how to cosmetically restore them and do the most basic of repairs. At least now I know what MIGHT be wrong with them and have an understanding of what makes them work. I have had the two-knob version of that radio for decades, and won't be plugging it in anytime soon...
Thanks Paul I enjoyed the long video.
You're very welcome!
What a beautiful job! So nice to see it!
The white paint overspray might be the same reason as I see most of them with white dots around here: older radios usually are put into the rooms during renovation and people don't cover them up - "it's just the old radio and will be replaced soon" - and then it's all white wall paint spatter from some paint roller for them.
That does make sense.
Mrister Carlsons lab you are good at restoring antique radios and alignment of antique radios my friend
Just what I needed on this"post monsoon" day. Lovely little radio, Paul.
I'm always pleased that you reiterate the proper method of wiring the power cord. It's an important lesson in safety that bears repeating!
Not going to lie, I was a bit saddened when you discovered the audio xformer was bad. Considering how out-of-whack all the adjustable caps were, I think somebody started turning a screwdriver in the hopes they could get audio output, not knowing their efforts would be in vain. Totally impressed with your repair on it, and also impressed that you would consider repair when you probably have a Big Box o' Parts and could have swapped it out more easily than repairing the original. However, that defeats the "restoration" as it would then have a non-OEM part installed.
I'm guilty of using "unorthodox" antenna methods myself, although for FM reception. A home's cold water supply (well water) makes a rather effective antenna in a basement. 😆
Beautiful restoration, as usual. The night-and-day transformation at 28:36 was amazing, such a clean job!
Thanks for your kind comment Andy!
