Yes! A 2 hours long video from Mr Carlson's Lab is a great way to start Sunday. Thanks.

That was such a great way to start the morning Paul. That radio is beautiful. Great job on the repair and alignment. Thanks for sharing.

You are the only one that can make me look and listen to a video of almost 2 hours about an old tube radio. And I mean that as a compliment! Another great video, thank you!

Thank you Mr. Carlson for another great video. As a child of the early 50's I can recall my first electrical experience. I had a habit of taking my mother's bobby pins and pushing them into electrical outlets. They were lacquer coated I think back in those days, so I was saved from disaster until one day I scraped the insulating lacquer off the bottom of the pins where it had accumulated into drips. The result was I blew out a lead glass fuse burning my fingers and getting my parent's attention. They installed child proof outlet protectors as a result. Not put off by that action, I learned how to rotate the plastic protection cover of the device and was discovered doing so by the old man and he immediately administered frontier justice. Needles to say I stopped that behaviour but developed a habit of looking over my shoulder before plugging stuff in for years, Hi Hi. My first electrical education at that tender age, was when the Sears Silvertone radio stopped working and the old man took it upon himself to pull the chassis and take the tubes down to the hardware store to check them out. Lo and behold, one of them was kaput so he bought a new one. Upon arriving home, he reinstalled the tubes but the radio still would not work. He got very frustrated and caught my mother's attention. She quickly realized he did not put the tubes back into their respective sockets. She arranged them accordingly and the radio played on. She was a registered nurse and did things precisely by nature. Your caveat about making sure the tubes are in the right places, dislodged that long forgotten memory. It was a general lesson I never forgot, that everything has its proper place. I love your stuff, you are a great teacher. Thank you

A new video from Mr Carlson's Lab is more exciting than a new Star Wars episode, even - or because - we already know how well it will end. This ressurection of a time capsule from the distant electromecatube era is a masterpiece. Thanks.

My favourite type of video, Paul. A radio/receiver repair & restoration. Two huge mugs of coffee on a Sunday morning.....just can't get better!

There is always something fascinating about these old "valve" devices. (I'm from the UK). Its the way you can tell whether the guy building it took care and the story they tell of years of use and the attempts at repair. Something truly mesmerising that isn't present around printed circuit boards.

People pay thousands in schools learning what you give us free. Thank you sincerely for sharing your wisdom on electronics.

Thats really something, Mr Carlson. Vacuum tubes that are 77 years old and still working fine, while manufacturers can't make a led TV last more than 5-7 years before the caps blow out in it. Back then, things were built with pride and designed to last....things today are designed to fail with planned obsolescence so the manufacturer can make more money..its sad.

Always a great "show". My late brother, Monte, W6CUW, used to refurbish boat anchors. He did both amateur radios and broadcast units. He went so far as to gut the old wax caps and put modern caps inside the shell and refill them with wax. A friend of his did precision cabinet restorations. Between them, they did quite well.

2 hours?? 2 hours of Mr. Carlson radio repair?? Happy Sunday morning everyone!

I have the same radio, which I purchased at an auction about 15 years ago. It is in working condition, but missing the correct volume knob and the dial cover. I didn't understand how the "magic keyboard" worked until I watched your video. I will now have a go at tuning them to some local stations. Love sitting in our screen porch on warm summer nights listening to baseball games on it. Reminds me of hearing games with my dad 60 years ago on a Philipps receiver. Thanks for the great video!

What can you say.........Wonderful production values and professional from start to finish a wonderful 2 hr watch, Just fantastic the best on KZfaq. Loved when you dimmed the lighting to show us the beautiful gold dial in it's full glory.......Thank you!!

First time seeing an alignment done on any radio receiver ever. Know the theory but never seen the practical. Brings back memories of bygone days. Those if's were really outta whack. Really a well kept valve(tube} radio and made to a high standard.

Your explanations of each section are some of the best I have seen on any restoration project, be it KZfaq or elsewhere. Normally I get quite bored with long videos, but yours seem to leave me wanting more. I have limited experience with Valve/Tube circuits and you have taught me a lot just from watching the restorations. It still amazes me just how much thought and intelligence went into these old electronics compared to modern equipment. The hum-bucking coil, as an example, is just pure genius really. Simple, but it works. Could you maybe do a short video on speaker cone repairs in the future? Thank you for all the restorations and information, past, present and the ones still to come.

Wow, that Art Deco dial is gorgeous. It surprises me how many AM stations you still got. In Europe that ship has sailed. FM is soon to be empty also. Sad days are coming.

As I watch you bring these devices back to life, I like to imagine what people were listening to when they were brand new. I can picture families setting around the set listening to fireside chats, reports from the war correspondents, Burns and Allen, Jack Benny, Milton Berle, etc.

Your restoration / realignment videos are always my favorite! This was absolutely superb, Paul. Thank you for taking the time and effort. I found a Stewart Warner 206FA (lass fancy model) that I had completely gone thru and it works and sounds great. Yours is a real gem! I'm so glad you are here to share this with us. Keep up the great work. - Mike

I am an auto mechanic full time I really love watching your videos Mr c when you speak of voltage drops gauge transformers coils DC AC rectifiers you're speaking my native tongue thank you buddy and giving me hope and humanity

Paul this one of my favorite videos i love the performance of this unit and how much time you take to explain and perform the aliment procedure well done

Man there's nothing cooler than the sound of radio stations being just barely received, some of those sounds around the 1:51 mark are so cool. All the flanges and whistles and distortions and so on, it's badass.

Another "A number 1" restoration project from beginning to end, Paul. You do such a great job in explaining everything. I always learn something new watching them, and I've been in this 51 years. Thanks. 73 Harvey KM4JA

Stewart- Warmer was based in the 1940-70's in Chicago. My father was with them for 16 years. During WWII they started producing gauges and sending units, vacuum tubes and radio equipment. In the 1950-60's they focused on gauges and got away from Radio production. Every young person with a " hot rod" car wanted a Stewart Warner Tachometer or oil or temperature, volt or amperage gauges. You will also see Stewart- Warner vacuum tubes. would really like a Stewart Warner radio to restore! Beautiful work, a joy to watch.

Looking at several of your videos, both repairing and restoring electronic equipment, is more entertaining than watching a good detective story!

New subscriber. Hi everyone! Just wanted to mention how much I appreciate the way you present each repair video as a teaching exercise, with those of us at home, your students. Your content has helped expand my understanding of consumer electronics and their design. Highlighting not only how to repair or replace a particular component, but also what function that component provides, leaves us better able to understand WHY we may want or need to replace it. Many channels do a fine job of detailing the necessary steps needed to effect the repair of any number of electronic devises. Few, however, take the time to explain not only what to do but why we're doing it. By the video's end I always feel as though I've just had a full meal, not just nachos. Thank you.

I wish I could remember who pointed me to this channel - because I no longer sleep for binge watching... I am wanting to build a vacuum tube, bluetooth amp now... why? Because Mr. C has made tubes fashionable again

Mr Carlson? I cannot imagine how much time you put into these videos. I've made some videos (albeit, bad ones) and it always takes 10 times the amount of time I think it will. I can't imagine what amount of time you spend in this stuff.. We all appreciate it!

A 2 hour video!!! Mr. Carlson has so much knowledge and information to pass on to everyone, and this takes time. Enjoyed the video so much. I hope there are more 2 hour vids in the future.

My dad (b. 1898) said he would connect the antenna wire to the bed springs... :-)

The Stewart looks like he has a small heater over the main dial, that keeps the wife's hands warm while she knit socks and listen to the music from the fifties :) What a great long video Paul! Without your videos I'd never see such a great receiver. I've enjoyed every second! Many thanks for sharing this!

I really enjoy the 'in-depth' coverage of your videos - all very thorough and complete - makes interesting watching!

Great video so far! I’m about 25 minutes into it. Going to finish it at work today! Love an in-depth Mr Carlson restoration!

I traditionally work on field phones and historical battery powered electronics. A friend asked me to look at a Silvertone 1 1950 radio he found at an antique shop. He plugged it in and the tubes lit (It had a worse cord than this one! :o I'm surprised he did that and didn't get shocked). This video was very helpful in realizing I'm more than a bit out of my depth, capacitors and resistors I can work with, but this radio is one of the non-transformer ones you described near the beginning and unless I build a isolation transformer like yours I'm not going to mess with it. I'd rather let it be history, not be history myself ;)

I've had professors like him. they left me feeling that a 2 hour class was way too short and ended way too soon. Great video.

Very nice. Today we learned about reading old resistors (b.e.d.), how to use the old o-scope made into a curve tracer, field coils, voice coils, and hum bucking coils. All new to me. Favorite quote: "That is a very very bad capacitor, I would say its a resistor" at 105:36. 73.

I think my great grandfather had the floor version of this same chassis! It had the radio on top and a 10" speaker at bottom , beautifully crafted wood cabinet and openings at the back for air cooling. I wonder what happened to it ! I greatly appreciate your videos as I was a RF engineer in the vacuum tubes era ,long time ago. Keep this videos coming .:)

I’m at a loss for words your brilliant I as a restoration guy a jeweler, and horological guy I am now on a new quest to understand the old radio world and it is so intriguing to me . I know nothing and am starting at 0 . Just want to say thank you . Just brilliant the level of knowledge is truly impressive.

how can you dislike this, people are truly messed up

Paul Carlson-the only person who can produce a 2 hour youtube video that leaves his viewers wanting more. Quick question for Paul-how long does it take you to record, edit and produce a 2 hour video? Thanks, Ian

I am a very old retired technician who loves watching electronic repair videos on You Tube. And I have watched HUNDREDS of videos relating to tube radio resurrection, repair, and tuning. So far you are the ONLY technician I have seen who does the job CORRECTLY! All the other videos done by the other so-called techs only make me want to throw up! Keep up the great work educating everyone on the proper way to do the job. I hope the other electronic repair techs start watching and learning something from you! Thank you for the educational entertainment! Regards, Dennis O.

I had to watch this one again!!! I get so disappointed when I watch any other videos on repair or restoring vacuum tube rigs. It is almost like the other people have an attitude of "Let's see how lousy I can make this and still have it work...somewhat. Even when you do the least that you do on a particular piece of equipment, it is far better, more professional, and easy to understand far beyond that of any other videos out there! Keep up the excellent work!!!

Now if this were a transmitter, alignment instructions would be, "tune for maximum smoke." Seriously, great video and well done. You have infinite patience and great attention to detail.

Excellent instruction! I'm a retired technician and former instructor. This was a good refresher course and I learned something new as well.

I grew up for my first 8 years in very rural North Dakota. Our farm house had never been wired for power, and had no plumbing, so our entertainment was an old battery pack radio. I was so proud of our radio because it looked very modern with a nice straight dial, and a small red flag that dropped down in a tiny window in the center of the tuning screen to indicate the radio was on. There is something about old tube driven radios that gives such a wonderful tone to the audio, and I guess the speakers were much larger then their replacement solid state radios. My heart warms when I hear the old mysteries that were so common in the 50's when we lived in that old house covered with tar paper to keep the Dakota wind at bay. The house was lite by kerosene lamps that lit only a small part of the room near the chair where my father sat, HIS chair was given only to honored guests, such as the Reverend, should he come to call, otherwise it was off limits, even if dad were out on the ancient tractor plowing the fields. When we finally moved to a rented farmstead that was closer then the 26 miles that the home place lay, the new place (to us) did have power, WHAT A DEAL this electricity was! First dad found a used radio, big floor model with a huge speaker that deliver bass that would shake the cobwebs when it was turned to loud, another thing that only happened if mom and dad were both gone, and eventually Dad found a used TV that we could watch, but I always missed that theater of the mind fro those old tube sets, and I think my love for electronics came from watching dad changing tubes in the radio when the sound became weak, or the stations seemed to fade in and out. So thanks so much for the memories, and explaining what those mysterious tubes in those sets really did! Dad always told me you had to look at the glow, and if they were dark, they were bad. Guess he had his own way to trouble shoot, he was born in 1910 so he watched as electricity came into use from the beginning, I guess he picked up a lot along the way, he was indeed one of the wisest men I ever knew.

Wow, you brought back some memories. I was a radio repair man and that looked all so familiar. That radio would have been just a youngster when I started. Many thanks for the nostalgia.

I'm doing a Zenith 12H670 that at least three people worked on before me. The last guy transferred parts from a 12A6 chassis (power transformer and the first filter cap), then swapped the 6V6G output tubes for 6V6es. 6 of the wirewound B.E.D. resistors are so burnt, I have no idea what there modded value was. The rectifier tube socket burnt completely away, so that clever gent shoved the now soldered-in rectifier tube under the chassis, taped in place with masking tape, and insulated the B+ with a theater ticket stub, plus more masking tape. The speaker is missing. The band switch was broken off. It's personal, now.

What a way to come back, Paul! You really were tip-toe for a comeback.

I grew up with a Stewart-Warner 2-band radio and learned about SWLing on it, so this repair was special. Thanks, Paul!

Paul, beautiful radio! I love your long videos. They're better than going to the movies!

I thoroughly enjoyed watching this video. Beautiful radio. I imagined listening to 1940's broadcasts there at the end...

Another wonderful video and repair. You do magnificent work and i am always struck by your incredible depth of knowledge. You are a remarkable person.

I picture some guy in the back of the radio store adjusting those trimmers to all the local radio stations, so when someone purchased the radio, all their favorite stations are just a button press away. The convenience of modern electronics!

Dear Mr. Carlson, Priceless video on how this chassis operates. You always do a very nice job on your videos, thank you for sharing this video....

Love the long form videos! Thanks for sharing this with us. This video is a great introduction of high voltage vacuum tube audio amps/receivers for the uninitiated.

Mr Carlson your vintage Stewart Warner tube radio Receiver from 1940s is so awesome 👍👍👍😎😎👍

Mrister Carlsons lab you are good at restoring vintage radios 📻 and alignment of vintage shortwave receivers 😅😅😅😅😊

Mr Carlson you are good at electronics restoration of vintage shortwave radio Receivers and Alignment

What more can I say Paul than, “Another superbly prepared, and executed video.” Regards, Phil.

Thanks Paul, another priceless relic from "yesteryear" being brought back to life for another decade or more useful life. I learned also about B-E-D markings on old resistors. J K

Thanks Paul, excellent as usual. I always hope your restoration projects don't work at first so I can watch your troubleshooting!

Great episode; thanks, Paul. I'm learning a lot about radios by watching this channel. Thanks again.

Excellent video. Mr. Carlson's radio engineering as well as his teaching ability is fantastic. Thanks very much.

Wow, to have your skill base. Great job on the radio, thank you for sharing this with us.

Mr Carlson you are good at electronics restoration on vintage shortwave radio Receivers and Alignment

What a beautiful radio..

1938-40 seems to have been the peak of tube radio production. Everyone wanted to get in on the post-depression boom by making radios it seemed. There are so many of these old radios still around today, that most of the popular ones really aren't very rare, and sell pretty cheap at flea markets and such.

Paul - I’ve never tried it, but I once read an article which described how people would use a short wire to attach the antenna terminal to the metal ‘finger stop’ on a dial telephone. The telephone lines were isolated from ground and made for great long-wire antennas. I’m just mentioning this because you were describing some of the different ways people attached antennas to these radios.

Oh man! A 2 hour restoration video, I settled in an watched the whole thing. Great video with detailed explanations. Paul you really do make brilliant videos for us. A lovely radio it is to. Thanks!

Alignments are so satisfying to watch.

These are unusually designed radios by Stewart Warner. They came in several colors from white to the standard Bakelite Brown. The back is nice but missing on most of these radios, and it did have a loop antenna on that back which would help the radio if present. There are people out there and on Ebay who do nothing but make restorations of radio backs. The Face Dial cover is plastic, but new ones can be gotten from Mark Palmquist out of Georgia. The face dial is small but attractive with its' golden color. One of these radios (in the brown Bakelite) came my way several years back and is now "singing again". Just wish I had the original back with the loop antenna.

Hello Paul, beautiful radio! Good work on repairing this radio! I really enjoyed tuning the stations! You are a very skilled electrician! I gave you a thumbs up! With Regards Miroslav from Slovakia.

I have one exactly like this radio that has been restored. I do need a back for it though which had an antenna coil. The push button latching action does work but are touchy. They were called "Magic Buttons" when the radio initially came out. I find this to be a very odd shape (which came out in a white color also) and one not used by other radio companies of the time. I did have to have the plastic Dial Face cover replaced. Also, I use a longer antenna as the original one was on the back which is missing on mine, so until I can find a backing will continue to use the long wire. I really enjoy this radio and the Bakelite has shined up nicely.

Videos like this learned me how radios work, not fail compilations.

Great video. Keep them coming. I love to watch and learn. Thank you Mr Carlson

Love the old radio, and once again great job. A radio that will be loved for generations to come.

What a lovely room . Surrounded by lovely gadgets

I hope your loved ones and house are OK after that huge ice storm you had over there. Best wishes thanks for all the interesting educational content. Keep 'em coming!

Hours of enjoyment watching your videos Mr. Carlson, well received and thank you. I very much look forward to your retro-bench series, recreating vintage troubleshooting technique with vintage gear. Best, best!-)

I love your full restoration videos. Thanks so much for doing this.

Very enjoyable video. I learned quite a bit about these old am radios from this era. Great to add to my basic understanding of rf communications. Can't wait to get my repair bench back up and running after many years away from repair. You would be hard pressed to find anything today that receives as good as these old radios. Perhaps something from C Crane or one or 2 other vendors. It reminds me how things used to be 45 years ago. Glad to see you survived the Ice storm.

Great video Sir! Gives me quite a bit more confidence in tackling my Hallicrafters S40-B and the horrible diode conversion I found inside.

You are a hero to me. You are Mr. Rogers for adults. You literally make me feel so much better after a bad day. Dude. You are my Therapist. Thank you. Do you have Merch? Can I get an autographed picture? Thanks.

My uncle had a radio that looked like that. They kept it on the kitchen table, and only moved it when company came, then it was put on a cupboard. It kept his wife and 7 kids well entertained

Sweet! Thanks for the new vid Mr Carlson, hope the weather is okay in your neck of the woods.

When my father and I were repairing old radios in the 50's we used Toilet paper and contact cement to repair speakers. We were careful to not get any glue on the flexible portion of the speaker just the flat sections and it worked fine. Better glues are available now but the old method would still work for speakers that are missing parts of the paper. Thanks for a wonderful video.

Two things that irritate.Why Far-ADD and not Farad? And from other videos you use variate as a verb instead of just vary! Love your work Mr Carlson. You have an extremely good analytic mind.Thanks for sharing.

Another great video,Paul!Thanks,again for all your time and effort.

Especially enjoyed this nostalgic trip back to the electronics of yesteryear Paul! Great job! Thanks, Jim and 73 de AA1JV

This channel is fantastic. Mr Carlson is fantastic. Great video as always :)

Thank you for taking us on the journey! 😃

Thanks for continuing the great videos!

Love how you enjoy digging out weak signals / DX. A true radio lover.

I love the looks of the era, especially the all wood models. The music of the 30's & 40's is my favorite .... big band = BIG RADIO.

Probably the coolest looking radio ive ever seen

What a Great video of Detail, full Brilliance, I viewed it fully, and liked it so much, I now want to refer to this work of art as my go to video, when I begin repairing/restoring vintage gear. Paul, is remarkable in every aspect of the word. Thank you very much Paul!!!

Thank you, I feel like I'm right there with you. Awesome radio! You have a new patreon.

My 4 and 5 year old grandsons approve....although launchpad explosions still win out?....go figure. Thanks for the video Paul. Great visuals and explanations as usual.

Excellent video, as always Mr. Carlson. Really looking forward to the video with the old workbench and populating it. Also have a Happy New Year! :)

A very enjoyable way to learn lots of new things!
