You never cease to amaze me Paul, and I'm sure that goes for anyone who watches your channel.
Another one for the couch tonight, awesome.
Take care, stay well. Best regards from Holland,
How do I contact you to get a quote for a restoration of my dad's Sony home stereo system, it has a bunch of included units, a TA-AV571 amplifier, CDP-CX571, ST-JX661, there is also a tape player unit and another one I don't have with me at the moment.. also the sub boxes have rattle in them too and probably need a restore. They are SS-U571AV. It would make a great video or two I'm sure..
Repairing stuff is great and all but building something is more educational. please build something from scratch, anything!
@@Haamedtm He does do builds as well, just not nearly as often and most of them are on his Patreon. Off the top of my head he did a nixie tube counter for YT, also some of the tools he uses he designed and built himself.
@@DankNoodles420 Electronic repair shops being as rare as they are now (most now just restore it themselves or sell what's left or throw it away) he probably gets thousands of such requests = probably has a lifetime's worth of work to do already.
Mr Carlson is the Bob Ross of electronics. I just cant get enough of this!
Entertaining Mr Carlson. I am a retired electronics/systems engineer (UK), but started out building valve radios when 9 years old, in 1962. So I enjoyed watching this. Repairing/troubleshooting old radios like this is an art and little to do with electronics knowledge per se. Thanks once again. A lot of modern digital electronics is so clinical and boring compared to old analog radios. I think a lot of young M.Eng graduates would not know where to start !
Thank You for your kind comment Philip!
Would definitely like to see the IF alignment and results. This radio is awesome!
Agreed!!
It's also different from the rest. Special mf 466Kc and multi band.
Greetings from Belgium.
I am on the edge my seat almost shouting, "it's a short in the filament circuit...there's an open wire!" and so on. It's just so much fun and the best part is learning the step by step trouble shooting procedures with the safety tips. Top notch video!
I’ve watched literally thousands of videos on UA-cam. Your channel has the best audio, hands down! Maybe a video on how it’s done? I’d enjoy that! 😀
Thanks for your kind comment William. I will consider that.
@@MrCarlsonsLab I second that request, and looking at your video setup also.
@@MrCarlsonsLab I'd like a video on how you "Mr Carlsonised" your Microphone ;0)
Maybe included as a part of William's request ?
You mentioned in another video, that you "tweaked" the mic, and gave a little smile :0)
I also vote for your audio setup to be covered. You have incredible audio.
Thanks I was wondering if ANYONE else noticed how much $$$ and money this guy puts into his work.Its the actual reason I first started watching him.
Considering the relative rarity and complexity of the tuner mechanism in this radio I think most of us would vote for a follow-up detailing the alignment process. Thanks for hosting a very informative and fun channel!
If you haven't subscribed to Mr. Carlson's Lab, do it now. His knowledge is totally amazing. Keep up the good work Paul.
I love watching someone in the modern world, using a combo of old school, new school and self made tools to fix old electronics!
Thank you Mr Carlson for another enthralling video. I enjoyed it very much. And how appropriate that your video be published just today. Sadly I lost my cousin and best friend today as a result of covid 19. He was an old radio ham, 86, and electonics buff, G3OTW. He was my mentor and together we would restore old valve radios in my shack. Sadly the seriousness of this pandemic is brought home with a bang when someone you love is taken. Watching your video brought back so many happy memories of me and Bill and the many, many paper waxies we changed together. Thanks Mr Carlson and 73s to Billy. Stay safe everyone.
I'm sorry to read of your loss Dave. I'm glad this video gave you some good memories. Stay well!
These old radios are simply beautiful. It is quite a wonderful contribution to our knowledge of these in the days of digital, that someone like you can share this knowledge with us. Keep up the great work!
That's an awesome radio, they just don't make stuff like they used to. Lot of pride went into that. Cool to see it working.
Was anybody else hoping the blue end of the pointer would find its way behind that wire break? It barely did for a couple of milliseconds, then nope. Haha! Another fabulous installment. Thank you, Mr. Carlson!
Love seeing these old radios come to life again. Never gets old.
The Person who swapped those foil capacitors definitely knows the outside foil tester and how to mark them with a red dot, that's for sure :) Many thanks Paul, for making this in Lab II. I really enjoyed watching this repair using a mixed of vintage or self invented test gear! Great Video!
Outside foil is no longer marked as it is considered irrelevant except in very high end high gain high fidelity applications.
You have to love old radios as they were all so works's of art and like old car's people took pride in owning them and treated them with respect.
One of my first electronic courses we had to build a 5 tube superheterodyne reciver and the instructors would leave bad parts in the binds.
You had put ever part and then test each part as well. Those two old teachers had a smiple way of teachers
I love it when people like you take the time to help bring those old machines back to life and in the process all so teach anyone who who may like to learn about those units and how to repair them.
Thanks for posting
Glad you enjoyed Terrie!
I especially love it when you use the old fashion test equipment to fix old time radios.. you are such a showman and a craftsman.
It still blows my mind how much care and resources used to go into electronics back then. Everything was a work of art. Same goes for old cars and buildings. Try building something like we had in the 1920's movie theaters nowadays!
It still blows my mind how much misinformation and absolutely mindless idolization of the “good old times” there is. The idea is that less resources is better! The fact that those old designs and manufacturing processes were resource hungry was absolutely not a good thing in the long run.
Now we got all the wonderful superfund cleanup sites from the “good old times” when resources were “not a problem” (a lie we dearly pay for now) and you could pollute like crazy and make people sick and nobody was any wiser because we didn’t know all that much medically yet.
If you talk about any reasonable performance measure, old cars (1960s and earlier) are universally terrible. Power to mass ratio, vibration and harshness, component life and performance (old shocks vs. current ones - night and day), cabin noise levels, emissions - you name it, it was poor, bad, or worse.
Those movie theaters from the 1920s? Nope. Don’t want them. They were temples of excess, used to pull in the masses because excess and gildings were a distraction from the relatively less glamorous everyday life. I’d rather everyone is able to enjoy some splendor in their own family life (in all sorts of way), and have the resources for it, rather than having to go visit a temple.
Modern tech is very resource-mising and it’s clearly represented in the prices of consumer goods. With not all that much money you can do at home what was barely dreamt of just 75 years ago. I’m glad backwards time travel isn’t a thing. Compared to what we got now, everything took forever and the simplest of things were an escapade. Want to watch a movie, rent a book, get some new music to listen to? You walked or you drove… I’d much rather walk or drive when I feel like it, rather than when I have to. But that’s just me.
And while working on old tech is a cool hobby, I’m glad a smart watch has multiple radios in it, and I can use it to play music wirelessly through earbuds that got no wires. Nothing shabby about that sort of progress.
@@absurdengineering Thing is these old things were designed to last a life time and be repaired and were normally made more locally. Everything is also done at huge scales now. Back then you had a small family run company churning out maybe 100's of units per month, now you have these megafactories in China churning out millions of units and sent on big boats all over the world. Way more resources are used now because of how globalized everything is and fact that stuff is designed to fail so you buy more often.
Red Squirrel You might be surprised to learn then that the price has some reflection of the resources used then :) If it truly used more resources, you’d pay way more. No magic here is possible. If you pay $100 for a widget, no more than $100 of resources were used to make it - not unless it’s dumped or subsidized. Absent subsidies, nobody can sell you a $100 radio if it used $200 of crude to make it. Nope. So that’s all there’s to it. Stuff’s cheap due to economies of scale. Shipping a million widgets in containers on a ship around the world uses about as much crude as that family company shipping those 100 radios around the US. I’ll take the ship, thank you.
I’ve said it before but I’ll say it again. The audio non these videos is amazing. I know nothing about electronics but still listen to every word. It’s just so clean
OH man, just seeing this cool radio gave me a nerdgasm. So very cool and retro.
I just stumbled on this channel. Wow what nostalgia. For I started in 1952 at DeVry Institute in Chicago, to learn radio and TV. I loved it and I was hired on by RCA service company; after I graduated from DeVry. I retired from RCA after 33 yrs in 1986.
In 1968 RCA opened up 6 training centers around the nation; just after color TV came into being; to teach technicians to install and repair Color TV's; because there was NOT a single training school that did it. One of these centers was in Miami and I became an instructor there. It was awesome.
I had NO idea there were people like you, still working on old AM radio's, etc. I am in awe. You, young man, are VERY well "trained" on things I used to teach. WOW!
I just cant get over it. WOW. I just turned 88 and indeed you have taken me back many decades. Thank you so much kind Sir.
Note: The "J" scenario when soldering, is a life long pet-peeve of mine. I would not do it, nor would I tolerate it. WOW!
Thanks for your kind comment Pat. Happy birthday too!
Ahhh...never to old to learn...at 70, you have shown me many new troubleshooting techniques...You have a profound natural talent and teaching ability...thank you for your dedication!
Glad you are enjoying Tom. Thanks for your kind feedback too!
At 76 I also have learnt from these videos
Would live to see the whole alignment. As a tech I loved doing radio alignments. Both transmit and receive. Just loved it. That was a life many years ago. Thank you for letting me relive them through your videos. Stay safe. Stay healthy.
Very impressive unit Paul. Also I have to say your trouble shooting thought process is superb ! These are the type of traps that stump many young techs when working behind failed repair attempts. Enjoyed the show.
That radio in the thumbnail is a work of art! Such craftsmanship-nothing like the featureless black plastic crap made now.
Mr. Carlson, you are a Canadian national treasure! Thank you! And yes, please do the RF alignment. Could you please also explain the intermediate and carrier frequency, the why, the how, etc?
I'd like to see a Series on carrier wave frequency also, explaining their advantages and disadvantages the long and short of it so to speak. I think it would be very educational...
It would be lovely to see this radio aligned, and working just so!
Another great video. Years ago I would not have believed I would find so much interest in watching someone take apart and repair an old radio. Thank you Mr Carlson!
Thanks 👍
I look at this electronic unit and all I see is man hours done by professional electricians and wood workers. Absolutely Gorgeous.
Dunno how sad this sounds, but, I really enjoy the re-alignments you do. Some of the best bits for me. It's great to watch you go through the trouble-shooting and repairs too!
Would love to see you do the alignment.
Ha, love hearing wwv!
what great work you do, resurrecting this old equipment that hardly anyone else cares about. So nice to see something rescued from the junk heap. Today's electronics are unrepairable, which is a terrible shame.
I disagree. I've fixed a couple of big screen LCDs which are a piece of cake. Everything is just module computer boards. The power light flashes the error code, and you can figure out (usually) which board is bad. Open it up, unplug the old board, plug in the new board.
Sure, you can't replace individual components because they are all surface mount (plus, there are few individual components expect on the power supply), but I think the most expensive repair I've done is maybe 60 bucks, and takes less than an hour.
You're a wizard, Mr. Carlson!!
I never get tired of watching you at work with these investigations and restorations. It's an inspiration! So please let's see the IF and RF re-aligned on this fine old radio. Looking forward to it and I'll bet the dial tracking's a bit off!
You have an outstanding channel Sir which has and continues to educate me. Thank you.
You are very welcome
Excellent video Paul very enjoyable to watch. Yes please let's see the alignment process. Greetings from Auckland New Zealand
Reminds me of playing with old TVs when I was 10 years old. I love that you keep the old things running and Interesting use of the meter (no cheap DVMs) & (no DAB radio upgrades) just restored to work how they where meant to be. You are a very skilled thank you for making the video.
Mr Carlson, your videos are like a good movie. can't wait to see it. an hour ain't long enough!!
Thanks so much for the memories. My father taught me how to fix radios similar to this back in the 1960s. Learned to always look at the previous repairs first because thats usually where the error was added!
I learn so much just watching your videos even though I've been in electronics for so many years dating back to the 1060's and had my own TV / Radio repair shop up to today where I'm working most of the time in modern computerized equipment. So many of the radios you get in remined me of how beautiful the cabinets craftsmanship was. I miss that today in "modern" equipment. No beauty, just cabinets. Even your workbench in this video looks beautiful ... I'd be very hesitant to work on such a beautiful bench. Thank you very much for sharing.
Thank you Mr Carlson for this video. These big old radios from the thirties and forties have a aura of wonder about them. It was the so called golden age of radio, Wonderful cabinets and often quite complicated dials and component layouts and short wave. When I was a kid my father had a short wave radio and I also built one in the 1960s and listened with wonder at all the overseas stations in umpteen languages.
Yes Paul, do the alignment for I've enjoyed watching the repairs. I want to see how this beauty from years ago and was really built for long distance reception performs! I love seeing them come back to life.
I for one have no problem with your videos being long. Thats more information for us. Yes i would like to see the alignment for completeness.
Hey Mr Carlson, I just discovered your channel and as a technician I extremely appreciate it. Can't stop watching your channel, such a educative, informative and attentive channel. Thank you very much for sharing your knowledge and skills with us.
You're very welcome!
I never knew a video like this would be so informative and entertaining to me. Electronics is not my forte, but the way you explained it and how thorough and Easy to understand you make it, is awesome! Great job, Sir!!
Glad you enjoyed it!
I wish you would make a calendar featuring your equipment. I would definitely hang that up!
Excellent as always! I for sure would want to see an alignment with the vintage test equipment on bench #2, done it old school fashion so to speak. Thanks for the time you put into these videos.
Thanks for sharing, Paul. Yes please do the alignment 🤗
Your sincere friendliness and matter of fact knowledge put a smile on my face... although I don't have the education to follow all you are talking about, I still watch your videos even if they take an hour. That is craftsmanship! No other way of putting that.
290 Volts , Man that could really put the Hurt on a Person , Having the Schematics was invaluable and , you being so observant , Great content , Thank You Sir . :) QC
Thank you for taking the time to share this with us. I'd love to see an alignment video.
it seams so easy just by the way you explain things keep it up sir respect from France !!!
June 1959 ? hmm ... I was born in June, I was already in the 5th grade then. Seems like 100 years ago. They used to make some beautiful things back in the day . Radios weren't just functional, they also made beautiful furniture. People weren't afraid to put forth some actual effort and pride in their work. What the hell happened ? I am absolutely glued to these videos for many reasons. I spend so much time here my wife has become suspicious, ha ha ha . No need for confusion, common sense and a bit of patience will take you a long way. Good work ! Now about that alignment ...
I would definitely like to see the RF alignment on this.
I would too, But I don't think it's that far off. Excellent sensitivity, so front end seems close, good selectivity so I.F. is probably pretty close too. Couldn't see dial real well so couldn't see where dial was when tuning WWV, so no comment on that part of alignment.
@@Rems61 You are probably right, I just like to watch the process. :)
me too
@@Rems61 It is inconceivable that this thing is still within spec. It may well seem acceptable but it will need aligning.
(Blimey, I almost convinced myself there...I'm only a quarter way through so don't know the whole story yet).
I was actually expecting to see it I did not realize time was coming to an end. I fully agree it would be nice to watch and see that end result., it is a beautiful radio.
I really enjoy you taking us into your lab and showing us how you get it done! I for one would like to see the alignment of this radio in the vintage lab for sure!! Thank you for making such great videos, keep it up!!
As a software developer, I found this video mesmerizing. Awesome presentation.
good craftsman tools with the life time guarantee...outlived the company...
Yes, I would like to see you bring back all your projects to life and repaired.
Great trouble-shooting skills, of course! This is a gorgeous radio and would likely cost a lot back in the 1930's Thank you.
Another excellent video. As an Englishman it's so nice to hear an American speak English. So often 'solder' is pronounced 'sodder' (53.00 mins). However in the U.S. soldiers are not pronounced as 'sodders, I wonder why?'
I studied electronics for two years. Ended up an industrial electrician/technician. Card plucker at best. That was a great video😎Watched the whole bloody thing. Would love to take up antique radios as I near retirement
Just wanted to say thanks for doing these UA-cam videos.
I've been binge watching them and trying to keep the political videos on UA-cam at bay.
You also inspired me to get into Amateur Radio. Started an online study and joined my local club as well as the ARRL.
I'm already part of your patreon for your electronics course. 2 bucks a month?! I can't go wrong with that. 😎
Transmitting from the vintage lab! Looks good!
Yes Paul,
Would love to see the video of your doing the IF alignment on this radio. Also, making sure that the dial matches the frequency of the signal received. Your video's are, as always, tremendously inspiring, educational, entertaining, and a joy to watch!
Don't you just love that "Umm... how is that working like that?" moment? lol
Mr. Carlson, this has been very enjoyable and helpful. Greetings from Cape Breton Island, Nova Scotia. Keep well during this time of isolation.
I love how when you got audio out of it the radio announcer was discussing artificial intelligence. Old machines to new ones.
That Westinghouse is cool!!! I have thr floor model version that was refinished about 37 years ago!!!!
Watching you is a bit like when I watched Bob Ross and the Joy of Painting. I'll never get as involved but it sure helps everything relax. May you continue to share your gifted knowledge.
Wow that was an hour long? That felt like 15 minutes! Entertaining video as always Mr Carlson, I learn more every video of yours I watch. Thanks!
Love this old radios. Must have been in the Niagra Falls area as some the orginal power was 25 cycles. Would love to see this treasure perform at its peak. Go for it. I remember some of the old Cathedral case radios of the era. My Grandmother had an old motorola table top and would always listen to the Gene Autry Show. If you listen in bygone tlimes your might hear Stg. Preston on the Challenge of the Yukon. I love those old radio programs. It made you see in your mind.
Man... You come up with the most beautiful radios to show us. Much appreciated!
Excellent way to explain possible problems, details for testing, overall function of the item.
When I was Engineering Manager of WDIV in Detroit my technicians told me about 25 Hz power in Ontario into the 1950's. They said you could look across the river from Detroit and watch lights shimmer.
I had no idea you initially had a 25 Hz system in the USA. When did it become 60 Hz, sorry 60 c/s.
Awesome to see the old-time bench in use!
I recently discovered this channel and enjoy it very much. Especially the mention of "magic smoke" when powering up a device for the first time.
Your knowledge, and your ability to explain and teach, are exceptional. Thank you.
You are very welcome
Wow, a B+ lead up in the dial lights section. I probably would have gotten a hell of a jolt from that one. Nice catch... never know what you're going to find in there!
You can never be too careful...old radios can pack a pretty strong punch
I love this. You absolutely rock the analysis and breakdown
Anything that you show and teach me is to my benefit. An alignment would be good
What an amazing channel. Mr. Carlson should have a television show, maybe team up with Uncle Doug.................. keep up the awesome work
A licence to receive a signal, sounds almost criminal, BBC.
lmao, nice jab
We have had to pay an annual license fee to our government to finance state radio and tv. Always been like that since radio started in 1924. This was terminated this year (2020). This helped keep at least the national stations free from all those braindead commercials...
Most governments (including here in Canada) wanted to control all frequency generating equipment during the big wars as there would be modulation on those generated RF signals that could be picked up by spies. Since all superheterodyne radios had an internal oscillator then that fell under those rules. Not so the TRF sets.
@Wallace Well, you have CNN NBC ABC CBS PBS all spouting the same propaganda. Maybe you ought to try occasionally hearing an alternative view.
A license to get radio reception legally. Bet that wouldn't last a second in USA. So they tax the electricity here instead!
Thanks, Paul! Nice troubleshooting on a gorgeous radio!
Great video! I would love to see the alignment. Thanks Mr. Carlson.
Your videos are amazing in the sense that you do this, so I don't have to! I'm impressed with the care Westinghouse took in this design around the power supply and RF. Yet somehow they tolerated such horrible loudspeaker drivers, in contrast to the effort that went into making everything else as good as they could. I always learn a lot, and am reminded of fundamentals, watching your videos. Thank you!
Awesome video, thank you! Also nice to see 3-gang variable capacitors radio's, not so common here in Europe :)
Wonderful video, thanks so much for putting this together ! If you decide to do and video the alignment, I would absolutely watch!
alignment!! alignment!! alignment!! alignment!! pls pls pls !! and a view of the radio closed in the dark to see the dial colors working on each switch change!! ty and really really nice video tutorial!!
Mr. Carlton comments cause my curiosity to look up the following:
1. Receiver license!,(oldradio.com) Canadian broadcast radio receiver, you had to purchase a license for it before 1938. 2. 25 cycle AC power used for early electric railroads.
What is the next best thing to problem solving? Watching someone else doing the problem solving. Thanks for the video...
I love your old equipment lab. That is a very nice radio that old Westinghouse. God bless and thank you for a great video.
Great fault finding Paul. I would definitely love to watch the alignment and clean up process. Hope your staying safe.
Being a sort of "electronic nerd" and l am fascinated with old radios I really enjoy this video. Awesome!
I would love to see how you do an alignment on this great, old radio!
Yes would love to see a complete alignment.
Nice job. Your intuition is amazing.
great to find someone that loves old valve radios ... please keep up good work I love to learn more
That's a gorgeous radio. I'd like to see a full alignment
That is a beautiful old radio and I would love to watch you do an alignment on it.
Hi Paul
I watch all your video , best video , please don't make attention what people say about the length of video . Those who like shorter can fast forward it , make longer film more details, even if you make 24 hours video , we love it .
I hope you don't get sick only .
