Proud Patreon of MCL ! 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..
@@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.
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.
@@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)
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!
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.
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!
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.
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.
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!!
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!
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 .
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...
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!
I would also love to see the alignment with your very detailed explanation. When I was a young tyke, the old feller next door gave me a Zenith tombstone radio. I used it for years and is currently resides in my "museum" downstairs. I have in my plans to restore that old gem and donate it to his only grandson. I hope he appreciates and enjoys that old radio as I did when I was growing up. I used to listen to the shortwave bands for hours on that radio. Cheers and 73 de N0YCX from Union, Missouri.
I know nothing about electronics and, being in my eighth decade, it's a bit late to learn. I was licensed in residential and commercial wiring, not the same as radio work. I very much enjoyed watching this video, and wished I'd had some kind of guidance in the beginning, and been led into electronics, including vintage radio repair. I had a stack of old magazines all about radio and TV repairs, and loved reading the articles.
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 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.
Archmage Carlson crackling and ionizing air (and his hair) with his lightning bolts and dark magic destroying puny plebeian repairs as he ascends willing gravity away and materializing his cape from thin air.... "Fiberous tubing, I command thee!" Amazing video as always!
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.
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.
As for getting shocked by B+ voltage while inside of a tube radio. In 1960-61 I was going through USN Basic Electronics school in Millington Tenn. We built a simple superhet radio. Our final was to trouble shoot. I failed because I got shocked by B+, Automatic setback to repeat that 2 week module. Still gradualted in June 1961.
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 !
Wow what a great video. I love radio. The cornerstone of my collection is my dad's 1949 zenith super Transocean still working. Well once again thanks. Best regards. Ronz.
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.
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.
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
Checking into 25 cps or 25 hz AC in today's standard of measurement was first generated at Niagara falls starting in t he 1890's and of course Westinghouse was involved. Since this was a Westinghouse radio I am guessing that Westinghouse company chose to use 25HZ because this frequency AC was well entrenched in Western New York. As late as 1925 a new plant generating 25 HZ ac was built at Niagara Falls.
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!
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.
Thanks for your great vidéo. The broken wire reminds me of thing we did on purpose in school for other students to troubleshoot. I had a maniac pleasure snipping the wires in that way by a millionth of an inch so the problems could not be seen with the naked eye.
Agreed, but I think it was more for receiving the Short Wave capability. They want to know what people are saying and thinking about, even back then...
@@steve-o6413 Depends on which country you're speaking about. The USA never had a license requirement to own a receiver, but other countries did, and of course, the socialist countries flat out banned ownership of radios.
Just wanted to say thanks for doing these RU-vid videos. I've been binge watching them and trying to keep the political videos on RU-vid 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. 😎
So this was an export model? For the USA and Canada? That's really interesting. Is that the reason for the 25hz.? You truly are a treasure, a world treasure! RU-vid is global. A great project. Thanks for not doing patron videos exclusive. I am unable to participate in your patron, but still love the ones available to plain old RU-vid! Thanxz
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
Tube rigs run at crazy voltages - 300V DC really! I wouldn't want to get bit by that. I wouldn't even want to work on this stuff, - unless I had a Carlson Super Probe. I remember that device from last year and man what an instrument that is.
Have not watched yet but no worries, they are ALWAYS excellent! Glad I was up early :D OK, finished watching and yep, it was great! It is nice to see the old time bench being used but a quick question. Why is the Vedolyzer not in it's case? I suspect that the case is a little too large for pushing back on the bench. Good advice on the dial paint too!
In one of the Vedolyzer videos he mentioned that he might use it without the case, because the chassis has a nice chrome finish. I guess that could be it.
another vote for an alignment video on this one! i'm hoping to find a video of your quality showing the alignment done with just a signal generator and an oscilloscope (which is what i have, no VTVM), (not sure if that's possible at the moment). i have watched your Echophone EC-1 alignment video multiple times, as well as the stewart-warner one and have taken a lot of notes :-) what i am not quite sure of is whether i could hook the oscilloscope up where the VTVM goes when doing the RF alignment (or maybe some other place). thanks so much for your contributions.
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!
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!
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.
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!
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!
The veneers on the radio look like tulipwood on the flanks and flame black walnut in the middle. Can’t see the sides. Please correct me if I’m wrong - very entertaining Mr C thank you!
Wow! What a nice fix. You found that break really fast. Love that super probe. Maybe one of these days I'll be able to join the patreon so I can get those great inventions.
One year I found a huge Majestik radio chassis & a old 1960s desk chair on the side of the road out of town. I sold the weighty chassis on 'greed-bay' & I use the chair in my radio room, along woth a huge metal desk someone else set out with a 'free' sign on it Nice to have a horse trailer to haul good stuff in.
