The CLEAREST audio on KZfaq. I love your microphone.

THANK YOU! I'm so glad I spotted this video. I have been looking for that exact model of radio and I did not remember what it was. I've scanned through thousands of pictures of old radios and never could find it. This was my dad's radio when I was a kid. We spent countless hours listening to Jean Shepherd's show on WOR 710 KHz in NY. I never knew what happened to my dad's little radio - its image was burned into my mind. So I've been looking for one for years. Thanks to this video, I finally know it was an Emerson AA5 - let the search begin!! And with a little more searching it turns out to be a model 805B from 1954.

Of all the stuff available to watch on the internet ?????? I would rather watch/listen to this fine man any time

As a tech of 22 years and a huge portion of that was my combat comms career on foreign soil, man do I learn a lot by your channel and videos Mr. Carlson. Great informative videos, awesome presentation and please keep up all the great work. 73

I have that radio. It was in my granny's kitchen, then in my dad's workshop.

Mr Carlson…. A suggested future tutorial….. recone a vintage radio speaker……. Thanks for all of your great how-to’s. Very much enjoyed and appreciated.

I'm nowhere close to being great with electronics, but I ****ing love your videos, both for the education and for your personable approach to teaching. Thanks again.

I've watched many, many videos on this channel and I am still in awe of the superb audio quality. I really appreciate your attention to detail!

Always amazes me how much Mr. Carlson knows about what seems to be everything, and too also be able to explain it in a way I can understand it. Being a member of his Patreon, is a godsend. Thank you Mr. Carlson.

Paul, you’re nothing but a radio genius. I am so impressed with your knowledge, your presentation, your teaching and explanation, and your complete and total knowledge of radios from ALL eras. Well done again.

Even as a techie who has been repairing radios for over 40 years, I find watching Mr Carlsons video here oddly satisfying, from beginning to end :-)

I really like your accent. It is so mellow and calming. Thanks for an interesting restoration. It is really interesting to see a tube radio come to life.

Mr Carlson your are good at electronics restoration on vintage shortwave radio Receivers and Aliament

"Scan the Band!" Every video has something new meaning there's reason to continue watching and learning. Theae early radios were like today's internet in that they brought knowledge to the people in efficient mode. Making them AFFORDABLE to the mass market tugs at Henry Ford's heart. Just keep the knobs on when using them. THANK YOU MR. C.

Great content, excellent audio quality. Most informative radio rework...wish I had Mr. Carlson to watch 40 years ago!

I had this radio at one time, but it was a dark brown bakelite. It was a good performer too despite it's small size. It was just that I was put off by the huge amounts of noise on the AM dial and lack of music stations. When they moved the aircraft and police bands off shortwave, it didn't leave much else behind. That is what really ended my relatively short foray into restoring antique radios. So I ended up selling all my antique radios off, save for four of my larger radios, which I really like the look of.

This small receiver is a teaching gem. I just learned a ton of pathway info from this video, and the simplicity of your delivery is amazing. Thanks, man.

I think that is the most compact AM-5 design I've seen.

Another great little radio preserved. What a neat looking little thing, very 'modern' design. 😊✔

Never saw anyone use a Balun type wrap like that on the antenna before. Clever idea.

Another example of the best teaching on the internet.

Emerson model 805B from 1954. Notice the PC 150 couplate, called the Audet output stage ,which was really new for 1954! See Beitman's Radio Diagrams from 1954 page 38.Another finely described radio repair! Thank you so much. Steven

Being a complete novice at electronics, these videos are amazing to me. I learn and try to understand every aspect of the repair! Thank you for the great work you do on your channel. Will be heading to Patreon asap!

Great fun. And, you're right, sometimes the coffee is a needed tool. Thanks. It's appreciated.

Adorable little radio. And I remain impressed at how many AM stations you can pull in, even with a relatively low-end receiver. Guess that just shows the benefit of an outdoor antenna.

I love that they cared about health and safety on this radio, even though it sacrificed the cosmetic looks of it, but they should've highlighted a marking on the plug connecter to help indicate the live prong so that you don't connect the chassis to the live 120VAC line as AC has no polarisation.

great video, it would be interesting to see some repairs on old television sets

I Have to say that I love your shop. It's obvious you care deeply about all of your stuff and it makes me feel good for what it's worth that you are proud of and share it with me. THANKS! KUTGW!!!

Mr Carlson the radio speaker is in good shape it looks like new that's so awesome

Mr Carlson your vintage Emerson radio Receiver AA5 with broadcast band is good for DXing at night and day that's cool

I really liked the topology / signal path discussion. Thank you.

Thanks Paul, I really enjoyed that restoration of the little Emerson radio. Brings back memories of when I worked on tube type radios in my younger days. In fact, thank you for all of your videos. You do such wonderful work on all of them.

Thoroughly enjoyed this video. Makes me relive the thrill of building my first serious electronic project as a 13 year old boy in 1965, an Allied Radio Star Roamer 5 Band shortwave radio. It started me in my 50 year career in RF, audio, video and IT engineering. Or maybe it was the #45 tube I got from a 5th grade friend who's dad had boxes of tubes in the garage. Either way, I love your work and videos. Keep it up!

Thank god, I was getting Mr Carlson withdrawal.....

A compliment to the industrial designer on this one. Beautiful and fully resolved. I wish I knew the names of all of the designers on the equipment we see on your channel. Even though the power cord is a rather lowly component it would have been good to replace it with one of the same colour, as the original designer would have intended.

Hooray another dose of carlsonitis to watch daily for the next month

I have trouble wiring a wall outlet, so my electronics knowledge is quite limited. The only radio I own is 20€ cheapie. Yet I watched an hour long video of a very knowledgeable repairman fixing a radio that is considered obsolete by the casual observer. Excellent, subscribed!

Thanks Paul, I didn't know the IF transformer had two adjustment points. Another great video.

I feel like I learn something new every time I watch one of your videos. Thanks for always taking the time to explain everything.

I always love how professional and detailed your videos are. Love this cute little radio :)

Word of advice for everyone playing along at home: make sure to mesh the plates of the tuning capacitor all the way before handling the chassis. You can see Mr. Carlson eventually did this at 15:15. If the plates are sticking out like in the video, you risk accidentally bending them and shorting them out! It can happen easily, when you pump into them with pliers or if you grab the chassis the wrong way.

I began my 35+ year electronics career at 14 years old with my boss putting me on 5 tube radios after a short course on tube checker procedures in 1965 in Clarksdale MS!! Still got six of them on shelves in my mancave! Can't part with them!

As always, thank you for you sharing your awesomenes! Your restorations and alignments just put me as about as a happy place those radios when they are done! 73 de N2NLQ

Sweet! I'm excited about the AA5 project! I'll be looking for it!

Thanks, I didn't know the detail about the smallish audio coupling capacitor used to reduce hum. I have a beautiful and slightly newer Emerson FM table radio that I've restored and aligned, and now I want to try going back and increasing the size of the filter capacitors a little bit and the audio coupling capacitor too. I'd love to see the Compactron 2 :)

Mr Carlson there is an AM station in Chicago call sign WLS. It has a clear channel at night. I could pick it up down here in Texas on my AM radio in a Datsun 210 easily. Frequncy was 890.

The radio is cute in such a 1950s (mid century) way! I wish there was more of these

Wow !! what a real gem from the past. Paul - you said something that caught my attention of Resistors going up in value - how and why does this happen. Could you discuss this as I thought a resistor was a pretty stable component . Thanks for a very informative video. As always You are a great credit to the industry...

Really nice radio Good job thanks for posting

Cool 5`s got me started in understanding radio! Remember the paper capacitors inserted in the ceramic cylinders, they were mainly use in TV sets. When they shorted, they would telescope out of the cylinder. A amazing view. Enjoyed watching!

Excellent restoration , and great sounding radio.

I used to make an 80 to 120 turn coil of 24 AWG magnet wire on a paper towel tube or pill bottle, similar to a crystal set coil, then connect two very long wires (over 200 feet each) strung out in opposite directions, and place the coil near my AM radios for super long range daytime reception. Normally we could get 3 or 4 stations during the day but with this I could get about 50. In NW Louisiana I could hear New Orleans, Houston, Dallas, and Oklahoma City at noon on AM.

Thank you very much, learned something.

Great clinic as always thanks for doing these vids! real well done Sir!

Awesome Video my Friend , Thank You !!!

Mr Carlson the radio cabinet color gray is in good condition that's cool

Another great vid Mr Carlson! 👍I would add that I always throw in a MAINS SUPPRESSION cap across the mains input. It's cheap and the number of times I've found it works well in reducing mains hum et I had a surplus of some old vacuum cleaner mains suppression caps and an 8 valve superhet Pye radio I restored was good, BUT the mains was not so clean... adding that, cleaned it nicely.

Thank you! Paul, I always learn something new! congratulations!

Mr. Carlson, as always your work is impressive.

These little radios can be tricky to fix. I really liked your video, I learned a lot! Thanks :-)

that pc is very very cool. Very cool channel; new and experienced engineers will learn something that can be applied to modern and antique electronics. It's content like this is why I pay for youtube premium. Thank you Mr. Carlson

I love you, man. This video, and the one about your new antenna, came out just as I was fixing up an S-38 and piecing together an end-fed antenna for it. Thanks for all your hard work, brother.

Very nice, thanks for sharing.

That was an easy one Paul and a cute little radio. I do like the style of North American radios, simple and clean designs. All the best 🙂

This is gonna be good!

Great video. Best DVD:)

really really cool... thanks....

Thanks for another great video! I enjoyed the loop stick antenna trick.That radio was actually so sensitive after you aligned it that stations were coming through the signal generator cable! I thought I heard CW coming through a couple of times too. I get a kick out of these amps on Ebay that (almost) ALL have the waxies still in them and there shown with the tubes glowing! Sold "As-is" with a "loud hum". I've actually seen used waxies sold on Ebay!

Thank you very enjoyable. Mike.

Спасибо. Очень интересный аппарат, как в плане простоты схемы, так и в плане компактности конструкции.

Another great video.

Love your work...perfect...

What a cool old 'relic' !

One of my favorite bedtime stories.

Great one again Paul. One video I’d love to see (either here or on Patreon) is how you get the great audio on your videos. I’ve tried various tricks but can’t get close on my videos 😊

very interesting mr carlson thank you

Nice video Professor Carlson on this really nice looking and well made radio for its size, year it was built etc. Well done !!

I'm glad you changed those capacitors, because those things can bake the tubes, and the transformer.

That's a cute little radio overall, but I dunno about the color! I'd really have to restrain myself from repainting it; good thing it's on your bench instead of mine! Thanks for another fun trip to the lab :)

Thanks so much for your latest lesson Paul. At about the same time that you had the All American Five radios, was had exactly the same type of thing here in the UK. However, as we're on 240 volt mains power here the radios had a large wire wound 'mains dropper' resistor that reduced the mains just enough to allow the valves (tubes' to connect in series just as they do in North America. The same arrangement worked with TVs record players, etc. The downside to this system was that the cabinet could get as hot as hell, and in some cases they even burst into flames! Keep up the good work and keep yourself and family safe.

A good little radio for listening to Coast2Coast Am late at night.

I realize you made the cord upgrade and isolation transformer connected . However and more importantly , you are handling the chassis powered up . I'd make a cautionary reference to your viewers , as to why you can now handle this chassis without getting electrocuted. They may not know your isolation transformer prevents the shock . You did not follow up with any reference to viewers that you could NOW handle this chassis plug in and turned on . Great detail on your work , very comprehensive .

Excelente: Un Cordial Saludo desde Cuba.

Your videos on radio restorations are always very thorough with all the details to help a viewer in the future. I view many restorations such as these from many channels and it seems to be common that there are disappointments when moderators find modifications that were not performed up to the standards of the moderator and or poorly or uncalled for modifications. Although safety modifications such as polarizing line cords and fusing seem logical modifications, some might consider that a radio such as this will be maintained in a collection and not ever to be used as it was originally intended. So in the far off future, in the ownership of someone else and if it needed servicing for aging and not for use so much, it would also be logical that it would not be taken apart by a child in curiosity as I did once. And when a skilled technician would open it up for servicing, the same words that are uttered today on KZfaq channels will be uttered then, "it is disappointing that this was done as the value of this nice radio has been greatly reduced." One might consider performing an exact restoration with the small dangers of the original design, considering the non-epidemic deaths from vintage radio restorations, one might install at tag with a string that says, "REPAIRS TO BE MADE BY QUALIFIED TECHNICIANS ONLY, HIGH VOLTAGE KILLS". I believe you have some of the top videos on KZfaq and keep them coming, very much enjoyed.

Most US made radios wouldn't have a schematic on the bottom. The missing paper probably just showed the tube locations on the chassis. As for working on an AA5, I won't go near one without an isolation transformer. We always called the ceramic multi lead devices "couplates" or "PEC's" for "packaged electronic circuits". Interesting that this radio so easily breaks into oscillation. I'm thinking that the compact design places components so close that there's enough radiation between the stages to cause a positive feedback loop . Sometimes reversing the antenna leads will help eliminate IF oscillation, though in this case, probably not. Most AA5's I've serviced haven't been this sensitive to oscillation, and I wonder if maybe the IF transformers in this set haven't been replaced with generic units at some point in its life. I guess Emerson was late to the game with printed circuit boards. RCA, GE, and Motorola had already begun using them prior to 1955.

Fine little radio Paul. Thank you for sharing your good work. Here in Germany there is not much left on AM, some foreign stuff. 73 de Olaf DK6KF

I built one of these is my high school electronics class as my final project, all discreet components and point to point wiring. . it used a 35w4 rectifier and a 50c5 for the audio amp driven by a 12au6 all of the heaters were in series across the 110v AC. Wish I would have kept it.

25:28 When was that radio made? Your coffee cup looks very period apropriate, like something my gran might have had. Lovely! ❤😊

That radio looks like 3D printed, cute :D

Nice :)

Late night makes me think Coast to Coast AM

I just finished an Emerson 543 which had a similar cardboard speaker guard.

Paul, I really love these restoration videos but Im not familiar with many of these older devices. I just wish you could give a little more background of these things - model number, age or year of mfr, etc. for historical perspective. Thank you Paul (In MA)

Cute little thing! Surprised that the case held up to the heat

I just restored a crosley radio which is a 5 tube series set, I have a real big antenna that just receives so much there is no empty spaces on the band which causes stations to overlap.

Would like to see you do a video on "starved-circuit" audio amplifiers, their practicality, and how to utilize them.

thx paul hope your havin a great day. regardless of your location and time :(

Looks very modern. IKEA style!

Mr Carlson me and my cousin are going to a Swap meet in September 11 Sunday morning at 8 am in Milwaukee 2022
