Paul, I´m still recovering after seeing this video. I´m from Portugal, and I follow all your videos, but this one touches me specially. I´m now 66 years old but my father was a great repair man of this old radios. When I was 6 years old, I remember to see him studing is radio lessons sent by mail from the Radio & Television Institute in Hollywod (I think), and all the money he could afford, was for paying his lessons. He gets is Diploma in 1959, and begans officialy working in radio repair service that same year. I was always by his side when he was repairing a radio, and I remember once that joking with me he asked: "Do you want a chocolat? Take this..." and he gives me a brown wax capacitor, like those you repalced...! Of course I did not eat it, but when I saw those capacitors today in that Rogers radio, my mind and my spirit... you understand Paul! He was ready to repair a Stromberg Carlson multi band radio (that one that has a mapa mundi, a termometer and a higrometer in the front) when he passed away one week before he begans... 14 years ago. I think the radio is yet in my mother´s house, (she is now 92) but not working. Maybe if I can find it, I sent it to you... who knows? Thank you for all your videos. I don´t follow his steps (I´m retired pilot from civil aviation), but I´m still beeing an Hamsphere radio amateur (31HS1209), and an official repair from Roco/Fleischmann miniature trains. All the best to you Paul. If I find the radio I let you know. If you want you can contact me via email ampsousa@gmail.com. Mario.

What Mr Carlson really demonstrates in these videos is that with sufficient dedication and knowledge, one person can produce studio-quality content that no TV network would have had any problem airing, back in the day when they still had genuine technology education programs on air. None of this takes special effects or extreme post-production. Lots of content on YT is overproduced, and often such overproduction seems intended to mask the sparsity of real content within the material. Instead, Mr Carlson spends extreme amounts of time doing the detailed work directly related to the topic demonstrated, not on fluff that ultimately provides no benefit. About the only production aspect I personally miss from these videos is second or third camera for picture-in-picture to show oscilloscope or other test gear readouts. Some newer videos have this. The small Tek scope within view works fine as long as you watch on a big screen. On phone screens, the digital mini-scope is hard to see. That’s a rather minuscule gripe, because the content is undeniably solid and straightforward - so simple yet it takes so much effort to do it well! A lot of people have no knack for explaining things clearly by reducing them to rest on a minimal set of background knowledge, and building on top of that. IIRC this is called a constructivist approach to teaching, and it’s a fundamental skill that at least used to be taught in theory of pedagogy. Mr Carlson executes this well and it shows: every explanation requires only minimum prior knowledge on the part of the student, and is quickly built up from the basics. The ability to build up explanations from first principles is what distinguishes teachers from pretenders. The latter have tenuous grasp of subject matter and are unable to offer continuity from the basics to the advanced material taught: they hand-wave a lot of it away. Mr Carlson does this only where otherwise it would detract from the primary topic, and even then, he usually offers another video with in-depth coverage of the applicable topic. This seemingly basic principle in explaining things is often completely missed by others, who build pedagogical houses of cards where but a sneeze of a student makes the whole thing fall down. This EE is very happy to be shown how to work with vacuum tube technology. Not having a decent grasp of it made me feel sort of naked. Not anymore. Kudos, Mr. Carlson. Every minute of your content is worth it.

It's difficult to find the right words to explain why I appreciate Mr. Carlson's work. Absolutely worth the patreon. Thank you.

My Grand Mother had a beautiful radiolike this one and no one knew how to restore it at the time. It did not work but was so lovely she did not want to part with it. ,I dusted it evey week and used Old English Red Oil on it twice a year. thank you for restoring these lovely works of art.

I always love your explanations as you go through restorations or repairs. :)

2 hrs of Mr Carlson's lab is better than any movie of equivalent length, you deserve an Oscar! Big Thank you.

I'm beginning to doubt the varacity of your restoration. None of the equipment you restore is anything like the radios I restore.Where is the rusted chassis, mouse nests under the chassis, mouse droppings in the variable capacitor, mounds of dust and cigarette smoke covered tubes,missing veneer,paint splatters on the cabinet, and that's the good ones. All kidding aside, I really like your videos, always learn so much, you set the bar very high for all of us.

I heard a tech state that he didn't care about the capacitor shielding effect; that is didn't matter in most cases. The argument here is that this mental attitude is sloppy: You should ALWAYS put the electrical component in use (whatever it is) in the best possible configuration, even if it does not matter in the particular case. It shows technical competence and professional pride to always do the right thing, period. It also creates good working habits that sometimes may make a job work better than expected, since something that did not seem to matter may be found out later to be important due to the layout of the device causing things to overlap in a way that had to be implemented due to lack of room or some other design change. Good work ALWAYS causes minimum problems...

Your videos show that these older radios were beautifully made and made beautiful. They are a work of art. Most of what you went through went way above my head in understanding.

Yes! An almost two hour video from Mr. Carlson himself! 🤗 The weekend is saved! 👍🏻

I wished I had discovered your channel before my grandpa passed. (RIP PAPA) He got me into old radios as a kid when he gave me a couple. I was a young dumb kid and didn't take care of them. Now, they're long gone. Wished I could go back and save those radios. Your videos remind me of him in the sense that you both knew your shit. When you speak, you are gonna learn something if you listen, thats how he was to me. He is the big reason I can do just about anything with my hands. He always told me as a kid, "if you aren't rich, and you're a man, you need to know how to fix your own stuff so you're not giving some guy who does your hard earned money to do something you should be ahble to do yourself. " Electronics are extremely overwhelming for most, at times. The amount of wisdom and knowledge you share, I hope most appreciate it. And I hope you remember just how much you in fact know and just how much information and know how you share with us. Thanks as always

This guy is a real pro, I could tell from just the first few seconds of the video. Love that lab, and great camera presence, too!

It never ceases to amaze me how much I learn from your videos. Thanks.

this guy has such a soothing, calming voice. Ive used this video countless times for background noise when im drawing, doing chores, and once or twice ive even managed to doze off listening to him! he gives both good information and relaxation in nice, long videos.

OH MY GOD! That dial diffuser is amazing! I am thoroughly astonished.

i love when you fix something, explaining very thoroughly along the way, then you ask us "do you think this will work?" :D mr carlson has just finished, of course it's gonna work!

I don’t know what you are doing but I do know you bring old radio, SW, HF etc back to life. I can only think of it as finding an old car and running through a very very high standard garage and seeing it come out the other side better than it did when it came out the factory. Genius

Damn... That was creepy, But that's what happens when you listen to a video that's several years old at this point hearing the dead speak again. Amazing Work. Beautiful Radio.

I believe God has Blessed you with wisdom on Electronics. Thanks for sharing and I love them all.

Though I am not a novice in electronics, each time Paul is teaching me something new. BTW, that cabinet looks so gorgeous, I would steal it from an old lady while she was asleep!

Thank you for outstanding video Mr. Carlson, one of your best! Trivia Question: Tube is an early UHF triode, looks like the CFT-15e used in B and C-Band wartime radars and radar jamming equipment. Those two capacitors are of the paper type, these are the obnoxious "WIMA Tropidur" (TROPIcalized and DURable), neither was true, dirty lie, they always fail to 100% Lost count of how many I have replaced, thousands maybe. Dunno. There was also a cap built by another German company, ERO which failed just as often. As a young teen in the 1970s my mates and I used to scavenge around for equipment when when the council dumpsters came on a special day to collect the bulky refuse people had put on the sidewalk in front of their homes (about once every 6 months, was called "Sperrmüll" for all the german speaking folks here). Lots of not-so -old radios and TV sets were saved by us and we tried to fix them, often with catastrophic results accompanied by smoke. One of the mateys dad was a techie at the local Telefunken plant and he saw there was no way stopping us lads so he rather gave us some tips on a regular basis on troubleshooting and safety, like a current limiter bulb inline with the equipment, rubber mat to stand on etc. He even organised us with an old analog multimeter, but poor guy , he had to teach us from scratch, we we didnt even know how a radio worked in the beginning, very patient man, I am still very thankful for all the time he took.. About six months down the road us guys were getting pretty snap at fixing the radios and TVs, there was no internet, no computer games to distract us, fixing stuff was our game, and one day our techie dad showed us how to build a primitive cap tester with a tiny neon bulb, limiting resistor and supply voltage pinched out of an old tube radio. This was applied to each end of the cap, and if the neon bulb just did a brief flash and went out the cap was ok. If it was leaky the neon bulb stayed lit. And that is where we found out about those trashy WIMA and ERO caps, made diagnosis even easier. We later built an improved cap tester with a salvaged magic eye tube. Anyhoos, the repaired equipment was sold by us guys on fleamarkets for a few bob or given to needy people who could not afford to buy new, often for just the price of the components needed for repair. Our true payment was the KNOWLEDGE and EXPERIENCE gained back then, every one of us "techie teenies" breezed through tech school and are in good employ today.. Best regards from Germany

Very nice job indeed Paul; thank you. That Rogers radio is calibrated now like a Swiss watch, & looks like a piece of edwardian furniture. Beautiful.

These videos are masterclasses in conveying information to the watching audience. Mr Carlsons clarity of speech and thought are a real treat.

An engineer and an orator! Your videos are always a little joy, thanks

"hi id like to buy a tester", "you don't make a tester for that", its ok ill make one myself" . you are a very intelligent man

Wow, that whole thing is in great shape, and its only a radio, no phonogragh, or tape player, thanks for making the video of it

how can anyone give this guy a thumbs down????????????????????????????????????? how much knowledge and experience has this video just given us!

the radio is actually huge, Carlson is just a giant!

Another excellent video. I greatly admire your attention to detail as well as the extra effort you put into your work. Looking for the next video soon.

That tube at the end looks like the flux capacitor from George Jetson’s car. lol! That truly was a great radio. Excellent video!

We need more like you. So attentive to perfection. Love it.

Best 2 hours I have spent this weekend.

I do Marine repair for a business and love doing electrical . I am also a certified auto tech and restore muscle cars when I can raise the money. I have always wanted to learn electronics. I love antiques and old radios , I bought an old Radio Shack kit to learn electronics has the board to plug in your electronics it was an NOS kit and love the kit. I know you probably wont read this but I enjoy the hell out of your videos I dont know what you are talking about but you did a bang up job on not only the restoration but the video is spot on. I want to learn how to repair vintage audio equipment and turn tables. i wish I had the knowledge you do Paul . I am hoping to get my own youtube channel here soon waiting for soft ware for editing videos .KEEP UP THE GOOD WORK DON'T CHANGE A THING!

Just yesterday I was saying..."Man, when is Mr. Carlson going to do another restoration video? Seemed so long ago", and now here you are! Thanks for making my day!

I am from the old days of radio, and it really HERTZ me to not say Kilocycles or Megacycles. In all seriousness , that is a beautiful radio. I wish I could find one in that condition. Great Job in the restore.

It always make me happy when a gem like this, is not wasted or destroyed by some "wannabe repair man" but comes to a virtuoso like Paul! :-)

I have ran out of words to praise the fellow, just joyful to watch.:):)

I'm so happy to have discovered your channel, you do an A+ Job!! I just finished watching this video and it's a flashback to my childhood, 53 years ago my Grandfather gave me electronics lessons and we rebuilt various radios and amplifiers. It's a shame that Polypacks is long gone, they had amazing deals, also in mid 70s heathkit was all the rage, so many fun memories!! Thank You again, you're awesome!!

I have to thank you for showing us all on KZfaq that the old radio is worth restoring. Way better than putting it next to the crube. Keep on keepin on.

Very nice restoration Paul. Thanks for sharing your knowledge.

Got the inspiration to get my delco r1153 repaired. I knew exactly after watching your shows what needed to be done. After 3 months it is back and love listening to the songs its the 50s having a radio just like that growing up.

Learnt more about capacitors in the last 2 hours watching this than I have in the last 20 years. 👍

Lots of detailed explanations; seems I always learn something new. Thank You.

Jeez, this video is incredible! What amazing work you are doing to educate us. Such a great teacher. Thank you so much!

Super idea of using etched circuit board for the diffuser. Awesome!

After screwing up many an old tube set I restored two raidios and a 78 combo Last year... Thank you Mr Carlson. Will I watch a two hour vid. After the hours I've wasted. And not died, why not. He's good

Man your fast with the color codes. I like your method of adding zeros as opposed to multiplying. Wow! I finally get the color code thing.😃 You did a fantastic job on this restoration!

Extremely well explained! Listening to that radio takes you right back to the day´s of the Everly Family's Radio Show. Dad Everly, Mom, Don and baby boy Phil.

That radio is gorgeous, and you did a great job on it. It sounds great.

Paul, just one more comment, I have watched a lot of videos on tube radios, and I have to tell you this video tops any other video that I have seen, the things I am learning from you is priceless.. thank you again for this wonderful video, so interesting to watch.....

I spent all of 1968 going to electronic classes while in the USMC. Had to use a slide rule for calculations. Every set we worked on had vacuum tubes, no replacing cards and it seemed like every thing we were fixing had to be APed...awaiting parts...lol. So as I watch you doing your thing here I'm able to follow some but still amazed at all you know . Kind of wish I had stayed with it after the service. Keep up the great work.

They say never meet your hero, but I don't think you'd be disappointed with Mr. Carlson

2 hours of fantastic content from the "Bob Ross" of electrical restoration KZfaqrs. Perfect! *Grabs a cup of tea, moves to the comfiest chair in the lounge, throws the video up on the chromecast.* Now all that remains is to hear the Carlson Catchphrase "if you're following along at home, you're doing so at your own risk" :)

Another truly outstanding video from Mr Carlson's Lab. You post the absolute best videos in terms of content, detailed explanation, video quality, audio quality, and narration. I'm sure countless thousands of people out there have had their thirst to learn more about electronics, and its beginnings piqued by your teachings. Thank you for all your hard work making these videos. Take care, and have a great day.

Col. Eugene MacDonald the President of Zenith loved chairside radios and felt they would be the wave of the future. They certainly worked well next to a chair or davenport.

Thanks for this video. I love seeing these old devices returned to function. Great job!

Excellent project and very entertaining to watch. Thank you.

Hat Paul loving the new format, looking forward to more great videos.

I appreciate the detail of your restorations Paul. Excellent work as always.

Damn, those silver boxes are worth their weight in gold. If I was you I'd patent them You Sir are a genius I haven't dabbled in electronics for a long time, life and careers kinda got in the way. While I'll more than likely never be as savvy as your good self, I still find it all fascinating and being able to fix old stuff back up appeals to me And yeah Rubicon are pretty much the mutts nuts in caps, Nichicon and Chemi-con are also very good. Had to recap an old motherboard, a few had bulged so I figured "nope, do the lot" all redone works like it should

My Dad used to repair radios in the 1950s, I was a teenager and often wondered what he was doing with the Sig Gen (signal generator)now I am in my 70s and it is all explained - thanks.

Wow. Nice radio. Hard to believe it's 70 years old. Thanks for sharing your tips. Thoroughly enjoyable video.

I AM 81 AND DON'T REMEMBER SEEING ANYTHING LIKE THIS WHEN I WAS NINE...MUST HAVE BEEN A RARITY..NICE VIDEO...THANKS...

Great radio and very interesting repair. Lots to learn from your presentation.

Thanks Paul for an enlightening two hours

Thank you for your extremely detailed explanation of capacitors and resistors. You put my electronics lecturers to shame.

Great as usual Paul, I always learn more every time I watch one of your video. Thanks so much and 73!

At first I though you were working on a clothes hamper....lol. Great video and thank you for sharing your knowledge and wisdom.

A great video. So well explained and easy to follow. I will be joining your Patreon in the near future. Thanks Paul.

Mr. Carlson, I really appreciate you sharing your knowledge on the vintage repair. It has renewed my interest on following your channel.

Oh Cool! I bought 2-larger radios from 30'-40's couple months back which basically got me interested in all this. Definitely gonna watch this one closely...Thanks!

Wow Mr. Carlson... I bought an antique radio like you have there. I was able to replace all the tubes and put in new Filter Caps. We also had a Bakelite AM Radio from 1949.. I repaired both.. Thanks for bring back the memory :)

I love to think back to this era. When radio was king and it was all anyone could hope to have. I still think of it that way. Nothing kept me company better than my radios in the 80 and 90s.

Excellent video. Your knowledge of early electronics is astounding. Thanks for sharing!

Sir, you give my life a purpose and a clear positive outlook. As always a BIG 👍 from me. Thank you dearly for producing content which is absolutely faultless. Your content is a credit to your person. I trust you embrace comfort, wellbeing and confidence from your truly fine efforts. Here’s looking eagerly for your next and very thought provoking presentations. May this long continue. Kind Regards my good friend, Steven.

This video has really motivated me to set aside some time and restore my 1940 Philco Floor model radio! To be honest I thought those simple safety procedures (removing the tubes, especially when you have the chassis setting upside down), not plugging it in without giving everything a good look over and thorough inspection would be common sense for most! Unfortunately a lot of the places a purchase these old radios from plug them in and end up letting out the magic smoke! Can't even express my gratitude to channels like yours who share information for working on these old electronics!

Very interesting and relaxing in a obscure way

In your videos, you detail your explanations very well. You explain why certain wire paths need to be routed the way you route them. Perhaps I might learn even more if I went to your Patreon channel. By far of any channel on KZfaq, your channel is the best for explanation. Looking forward to seeing the last video on the Vedolyser project!

yes soo nice, its saturday night ,and an upload from my fav electronics guy,.,nice,,this is my life

Really very nice. Very well explained. Anybody can learn easily. I am very much happy the way explained. I am very much interested in radio repairs by my young age. I was doing some repairs without knowledge of parts. Really superb🤝👍🤩💐💐💐

Beautiful work Paul, as usual.

What a nice radio! Sounds excellent!

Such a perfect little radio.

Unbelievabily great, Mr. Carlson! Thank you for another truly unique and wonderful presentations.

I LOVE your videos, you really find some nice pieces to show us!

I must admit I am jealous of your expertise when it comes to this type of thing, I try to pride myself on re-selling old radio equipment to the best of my knowledge and as I see it, however now as I see, your expertise in this field, again, I am humbled as to the depths of what you know of such equipment and so easily... I had started to hold myself a decent appraisal of such things, and yet you have showed me of how I know so little... Thank you sir. Being humbled of a field Is not so bad as not knowing as to what this "thing" does, as to well as "what" that thing "can".... (and why to avoid).... Thank you sir...

Radio was like TV at one time! Families gathered around the radio and listened to programs...some of which became televised in later years!

Wow nice job Paul, very educational, and great sounding radio. Thanks.

If that cabinet is unrestored, then it must be the finest example of it's kind in existence. It looks new!

Incredible video. Back in the late 40s we used to listen to "skip". I grew up with radio. Think what a radio would cost a family back in the day. I still have a collection of tube radios including a Zenith chair shudder dial. I'm not into radios anymore . Back in the day I went to DeVry at the time of change over to transistors and I learned tubes. Worked in the industry for five years and had to quit. Cheers, Lee

Stumbled in a while ago, catching up with videos. So geat to see another human being that knows what a loctal socket is. Nice work!

Vacuum tube looks like a CV933 made in 1940 for use as an oscillator in the first American airborne radar, the ASB search radar. Also equivalent to JAN-CIM-15E. Designed for low duty cycle pulse operation at up to 600 MHz. Max anode voltage of 15,000 volts! Nice video. Thank You

Outstanding video Mr Carlson. Thank you fo your time en dedication to make this video posible .

This is, as usual, on the ball Mr. C ! I must've been in some temporal anomaly though, because those two hours just flew by. Thanks man and I really, really need to get on this patreon thing of yours :)

Paul, you wil alway stay to my Top 5 Tech list here on YT. Just want to thank you! I alway have fun when you, TRX Peter, Buddy, Mike, and Defpom put up some new vids! 73 de Olaf

Those are WIMA Tropydur Caps. They are paper caps sealed with tar, they were advertised as being very resistant against moisture gettin in them. They werent. They were one of the worst caps ever made. Have you restored something German? Looking forward to a video about it!

Just discovered your videos and I've having a great time watching them. Thanks!

Very nice radio, great rebuild. Thanks for clocking down some of those long boring hours that God keeps piling on me whilst I self quarantine so as not to catch the China Virus. Your videos always keep me awake and alert as the hours tick away.

I love what you do Paul. Keep it coming !
