ok
Why don't you install small cooling fans in some of these tube radio's?
Would like to see the case restoration. I vote for red and gold. Curious What type of vintage equivalent paint you'll use.
I have this exact same radio only it is white bakolite .I have never refurbished it and it still works fine even the dial light works. I live in southwest Missouri and it picks up WSM in Nashville just fine at night. Just for a tast of nostalgia I like to listen to the grand ol opry on Saturday night from WSM Nashville from time to time and Ernest Tubbs midnight jamboree which is no longer live but recorded earlier at 10pm then played back at midnight. Great well made dependable old radio. Thanks for the video restoration. Now i will have to think about putting mine on the bench and doing the same .even though it still works fine I'm sure changing the capacitors will improve the performance and prevent future failure or catastrophic damage.
Mr Carlson a big thank to you. I have request Plz teach me electronics. I am noob and want a master like you but there is no one like you, So I want you to be my master. If you wil not respond to this i will write again and again. I am from India thousand miles away from you but distance doesn't matter from me. So teach me my master.
restore the case.
restore the case.
restore the case.
👆👆👆👆👆👆👆 What he said x10 😉😂
Amen, amen and AMEN!
What color? White and Gold is out. So Black and Gold or Red and Gold? Perhaps some other scheme? Hmmmm.
Silver and black to rock the robot head look.
Just have to complement you for having perfect audio levels on all of your videos. It's a rare thing on CZcams.
Thanks for noticing! I work hard to keep it that way.
Also a camera that stays in focus at all zoom levels.
@@Digital-Dan - It's easy to keep things in focus. Zoom into whatever will be in the shot, focus (or let autofocus do its thing, then switch to manual focus) then zoom out. Everything will be in focus from that point on.
@projectartichoke - It's very easy to balance audio levels in a video editor timeline. Once the video is edited to satisfaction, merely select the whole, and use the "normalize audio" function. It all becomes equal across all clips. In one respect, it's like the loudness button on audio gear, in that low level sounds are amplified, yet loud sounds don't exceed the maximum value. It's a form of compression, just like what is used in radio, especially FM.
No audio is adjusted in the editing program (on my end,) It's all taken care of on the analog side with vacuum tube audio processing equipment.
I would indeed like to see a case restoration. This is the main reason I watch David Tipton's radio restoration channel.
David does great work. He is another CZcams channel that should be better promoted.
Thanks for bringing back life to yet another great little radio, Paul. We had transformerless designs all the way up to the early 60s here in the UK, and I learned the hard way at a very young age that the power cord should always go into the socket the right way round! Back then we had three different types of mains power sockets, 5 amp two pin reversible, 5 amp three pin none reversible, and 15 amp three pin none reversible, all at the standard 240 volt 50 Hz supply. By the end of the 1960s all new house power sockets had to be of the now standard 13 amp, three pin none reversible type. I was born in 1952, and at sixty seven I'm still here, so the burned fingers I got in my early days taught me the hard way that the correct wires must be connected to the correct pins in the plug!
Thank so much for all you share through your CZcams channel, Paul. You have a world wide audience eagerly awaiting your next knowledge packed video.
Mr. Carlson.." it's just that easy!"
Me...." it's never, just that easy!"
Mr Carlsons lab you are good at restoring vintage radios and alignment of vintage radios 📻 my friend 😊😊😊😊😊
I always love it when you can restore an old radio from the 30s or 40s I find it fascinating to see the innards and you fixing it up with today’s technology
Nothing like working on some PCB designs and drinking coffee while binge-watching Paul fixing radios and designing circuits.Winner combination!
You're so meticulous in describing everything you do, it so mesmerizing! Love your vids...great job as usual!
Thank you so much!
Paul,
You are the Mustie1 (or the Mr. Blond) of electronics - thank you!!
God bless
Paul (in MA USA)
trained on electronics on the late 1960 , one of my first test was the building and alignment of the superheterodyne radio. Thank you making these videos,they bring back so many good memories. I am going to binge watch your videos.
Paul, your videos are second to none in terms of quality, education, safety and just plain ol' interesting. I don't always understand everything in your videos but I always understand more than I did before. Thanks for being a calm, soothing voice in these times of chaos. Keep up the excellent work! Oh, and the answer to any question you ask do you want to see me do X? The answer is always YES!
I'd like to see the case restoration as well, please. As thorough, professional and thoughtful as you are, I'd enjoy watching you paint a room! 😊
Mr Carlsons lab your vintage Robot Head crosley Moffat tube AM radio from 1947 is awesome my friend 😊😊😊😊
No matter how many videos I've watched, I always learn something new and fascinating with each one...Thanks!
There seems to be some who want to see the case restored. That’s not a bad idea. It’s your call. There are those who enjoy the full restoration. I am one. Shows more than tech skill, shows mechanical aptitude too. Keep up these great videos. 😊👍🏻🙌🏻👏
I would have preferred that you made a video where you sorted out the grounding situation and other issues. I really didn't need another plug for your capacitor tester. I would love to buy one though. All that being said, you are easily the most knowledgeable electronics guy I have ever come across.
Mr Carlson you are good at electronics restoration of vintage shortwave radio Receivers and Aliament
Alignment makes all the difference plus that radio has excellent sensitivity, another great video Mr Carlson.
Another fantastic video - one of the few channels that is really worth every cent of my Patreon contribution.
Very enjoyable. I'm probably the 99th person to say this, but you're the Bob Ross of vintage electronics.
Oh yeah, please restore the case.
Interesting radio and restoration--thanks Mr. C! This restoration has interesting timing.
As you may recall, I sent you a PM through Patreon a little over a week ago, asking about radios of this vintage not matching their schematic. Although I had not specified, it was my Crosley 52TF that I was referring to in that PM. Unsurprisingly, the schematic for my 52TF appears to be a direct ancestor of the 56TD here in your video. The circuit in my 52TF has many differences to its schematic, so you now know what I was talking about in that PM. I originally restored all of the caps and some resistors with the same/similar values as in the original circuit. Afterwards, when I was troubleshooting hum issues, I noticed the audio output section had many differences when compared to the schematic. I took many photos and then made the audio output section match the schematic, but that completely broke the radio--no B+ voltage! Even though it went against the schematic, I moved one wire back to the way it was in the original circuit, and I got B+ back. Now I need to revert the rest of the audio output section to match the original circuit. I'm still working through hum issues, but you've given me some things to try. I'm curious if the actual wiring of our two radios differs from the schematics in the same way. Thank you for confirming that Crosleys don't always match their schematics.
Regarding the new mica capacitor, connected to the grid of the 50L6, can you confirm its value, please? Is that orange-red-brown (320 pF)? I'm also guessing the upper-left black dot on that cap means it's mica (vs silver for paper).
People, if you enjoy Mr. C's videos as much as I do, please consider supporting him through Patreon so that he can continue such great content.

Another amazing piece of history saved... Fantastic work!
MR Carlson thx for loving my comment:) Even when am not at home Your channel plays ( it helps to distract thieves XD )24h almost:Pam uploading and downloading alot data so pc must be always on. bills are bigger a bit but not too much 40 euro per monthXD. Now am making my 1st LED torch from 130 lumen 1w high powered LEDS and connected 13 them pararel one by one , took heat sink from old pc. + am gonna use a little of 7.5W /mk good conductive thermal grease and spread it on metal underpads and then attach diodes to heat sink
Really liking the second bench. Looks quite roomy. 👍
Watching these videos makes me want to work on these radios, too. But I know nothing about tubes, lol!
Story about Moffats Limited... a Canadian company tied to Crosley:
In 1946, the Avco Manufacturing Corporation (formerly the Aviation Company) of Greenrwich, Connecticut bought Crosley Radio and Television which, in addition to its entertainment products, also made major appliances. The same year, Avco licensed the manufacture of Crosley products to Moffat. In 1953, Avco bought Moffat outright. From here, the story needs to go back in time. In 1927, five companies (McClary Manufacturing Company, London, Ontario; Sheet Metal Products Company of Canada Limited, Toronto; Thomas Davidson Manufacturing Company Limited, Montreal; E. T. Wright Limited, Hamilton, Ontario; and A. Aubry et fils Limitée, Montreal) merged to form General Steel Wares (GSW) Limited. They acquired the Happy Thought Foundry Company of Brantford, Ontario in 1920, followed by the Easy Washing Machine Company in 1958. In 1962, Beatty Brothers Limited of Fergus, Ontario acquired a controlling interest in GSW through a reverse take-over, merging the two large firms. Here's where Moffat comes back into the story. Under the leadership of Ralph Barford, GSW acquired the Moffat Company in 1971, making GSW the the only Canadian-owned, full-line appliance company. The Moffat acquisition, probably Barford's largest, brought GSW into the big six full-line appliance makers. The other five, all foreign controlled, were Admiral, GE, Inglis, White and Westinghouse. GSW merged with General Electric Canada in 1977 to become the Canadian Appliance Manufacturing Company (Camco), making it the largest major appliance manufacturer in Canada. The same year the company acquired the major appliance operations of Westinghouse Canada, exclusive of the "Westinghouse" name. Those products were re-branded as "Hotpoint" and sold along side of the GE, Moffat and McClary brands. Under Camco, stoves and refrigerators continued to be built at the Weston plant until 1983 when production moved to Hamilton, Ontario and then off-shore.

I really like the way you explain what you are doing. As a former electronic engineer, I do appreciate, thank you.
Thanks for your kind comment Christian.
Thanks Paul for another instructional video. I get lots of info from CZcams folks like you who help me piece together the workings of a radio. Cheers... Oh, and of course all Aussie radios have the tubes hanging upside down (I've been reading other comments) 🙄
Thanks David! You are making fantastic video's yourself. You are one of the few channels I enjoy watching.
“I have a screwdriver here” sounded as if that was a threat to the radio :’D
This was fantastic. I love the styling of this radio. Great video.
Very comact and portable construction for thats times( 1947!) 👍
I’d love to see the cabinet restoration. Also, I (like others already did) have to compliment you on the audio aspect of your videos. Always pleasantly clear and intelligible.
Mr Carlson the radio cabinet looks like new that's so awesome
i learned so many things from a video, i can't believe i haven't discovered this guy before!
Hello, Paul! I really enjoyed the video. I am always amazed at how many tests can be performed on one antique radio...with a final result of the component sounding so rich. As for the case, to be honest, I really like how it looks now. This is a personal thing but I prefer seeing a radio that shows its age but works great! Again, Thank You for making these videos. With the lockdown, these videos get me through the day and I learn something with every view. Keep em' coming!
Missed your smiling face youngman! Great restore ! I enjoyed every second of it!
I really love this videos. You do know a lot about electronics and electricity. It is very fun and entertaining to follow you along all these adventures. Many thanks
That radio would look properly cool in the black and gold colour scheme.
Your videos are just the best. You breeze through this radio like you have done dozens of this model before. I know we don't get to see all the work you do, but still, just awesome! You have to show us the cabinet restoration for sure.
Mr Carlson your Crosley radio Receiver from 1947 with broadcast band is good for DXing at night and day that's cool
Awesome video that is a joy to watch, thank you once again!
Great job! Very well done in every aspect. Top notch.
Loved the Crosley Fiver i restored, fun radios.
I always love the effect of hearing modern broadcasts coming from eighty year old radio sets, it's kinda Twilight Zone-ish.
This guy is brilliant! One of the teachers in this would.
Hey Thanks again Carlson will be watching this tonight. 👍
Reads well James.
All good! Excellent content, your standard of work is an inspiration. Thank you!
Yay! a new Mr. Carlson's video, the Crosley looks like a bread toaster to me :)
As usual.....your work is perfection. Also, yes.....would REALLY like to see the result of the finished radio with the black and gold! thanks!
Amazing lab, amazing work!
Totally enjoying your channel, well done. I was a TV engineer back a few years ago so its very nostalgic to watch your show.
Just a little hint for polishing glass fronts for you, you can use toothpaste instead of headlight cleaner, works every bit as good.
Keep up the good work 👍😎
Great video! I learned a bunch. Thanks for teaching us. YES, to restore the case. :-)
An other great job by Paul i really enjoy your video's and how you explain what you are doing thanks a lot !
Thanks 👍
I just discovered your channel today, after watching a lot of techmoan, 8 bit guy, lgr, reto man cave it's interesting to see the repair of old electronics. I can really get a sense of the evolution of technology. What changed and what stayed the same.
Cool video. I've learned a lot!!!
I think that the "robot's head" shape of radio as you put it is one of the ways that people try to make things look "futuristic". It's like when the first diesel electric locomotive was invented that they made it look more or less shaped like a space vehicle so that people would find it more attractive than just a box shaped locomotive like they use now. The thing is that people don't exactly know what the future is going to look like until it actually happens. Instead of Jetsons-style buildings, for instance, buildings look ordinary. But there was no Internet or cell phone or flat screen television or touch screen tablet computers or any of those things back when /The Jetsons/ were first produced by Hanna-Barbara.
You know has shape of a toaster probably why it gets so hot. Very good restore!
Restoration of the case? Yes, please! Thank you.
Great video, yes restore the case. new to this channel enjoying immensely.
I learned lots from this and it was fascinating as usual. The radio looks like it is about to say "Take me to your leader" :D I think if it had a gold grille and painted body, it would look even more like a robot head or something so I say just leave it in plain Bakelite. Cheers
Great video! You make the alignment process very straightforward and easy to comprehend. I'd like to see how you restore the body of the radio to maybe red and gold. Keep up the good work I am enjoying all of your videos and have learned a lot from them.
Grate video Paul really learned Lot
Mr Carlson the radio speaker looks like new that's so awesome
When you first powered it up, the las thing I was expecting was for it to work. Smoke yes, but not work. LOL. Nice job as usual, and thanks for the tip on dial cord replacement regarding the spring.
Another great video! I'll have to go over to Patreon and add my further comments. Well Done!
Novus #2. Get a set of #1, #2, and #3 -- the best thing ever for polishing things, especially plastics!
Entertaining! Thank you!
This design would benefit greatly from adding an exhaust fan to the back to pull cooling air from the front. Yes, fans are noisy but heat is worse than noise.
I just found your channel and have watched a couple of your videos. They are very interesting and informative to watch, however I have next to no knowledge base on radios, albeit I am a retired Mechanical Engineer - having been the safety Engineer on the Space Shuttle Main Engines. I have always been interested in the design of vintage tube radios, and just completed designing and making two sort of Prairie School wood table radio cabinets. One for my grandson, who likes old radios, and one for me. My grandson liked a Prairie School table lamp that I recently designed and made and wanted me to make one for him. Since it took me a month to make, I decided that I would make something for him that did not take as much time. So, I incorporated the look of the lamp into the radio, which still took me two weeks to made two radios. It would be neat to insert a tube radio in my cabinets for the great sound, but I have not found a good deal on a working one or two. So, for now I have 1970s vintage Tandy radios inside the cabinets. The rear panel needs to be removed to turn on, set volume and station - but only two screws.
Here is a quick and dirty video on my Prairie School Radio Cabinets for your viewing pleasure!
czcams.com/video/zvlVWGyhBf4/video.html
There's 36 people currently that thought that there would be an actual ROBOT HEAD.
Yes please! Definitely would like to see the final colour restoration. Thank you.
Well done!
Love the videos!! The best polish is Blue Magic (In the tube) cleans and polishes stuff is great!
When I saw the name Crosley, I thought it was one of those Junk Phonographs .
This is a Gem! I have restored some of those myself.. Capacitor and tube rectifier replacement..
Oh that Bakelite......
"I'm the leader of the show, keepin' you on the go
But I know I can't live without my radio"
- LL Cool J
Where do you even get one of those rectifiers today?
Crosley, like so many fine old companies, is now just a brand owned by some marketing wonks.
@@TheRealColBosch RCA Victor comes to mind too
That is so awesome how that radio goes from picking up one or a couple of stations to hitting something all the way through the dial. So much work but so satisfying. (I hope I am accurate with that assumption as you did all the work). :-) Thank You, again for another successful Restoration and sharing the "journey". I have learned SO much from you. I do need to get onto Patreon and learn the cap leakage tester build. That device is a "must have". And my words wont help pay your bills. ;-)
Your Videos are Outstanding and a pleasure to watch. I almost thought I would hear the music from the era when the Radio was made lol...
I have many mp3 files of radio programs from that era like Gunsmoke with William Conrad as Matt Dillon
I would love to see the Robot/Shaver Radio case restored. Great job as always.
These videos are fantastic. It looks like it was modeled to look like a cast iron radiator.
Mr Carlsons lab your utube videos are awesome my friend 😅😅😅
Perfect timing Mr Carlson. I just bought this model Crosley from a local Craig’s List seller that’s week. When I opened the radio all the tubes were missing. [Lol] Buyer beware.
Hi Paul. Great repair as usual my friend. Very interesting radio. Take care.
Good to see you Buddy! Have a great weekend.
Great video!
Another great video 👍👍. I can’t wait anymore for your leakage test, so fundamental for electronics restoration. Generally speaking I prefer to maintain originality, but it’s up to you 🤗
great video as usual
Excellent job for you and these radio really old as 60 to 80 years old working very well!! So I call you Prof Electronics!! LOL!! ;)
A radio only a mother could love. Very Flash Gordon-esque look to it. Strange how there's no ventilation. As the plastic faceplate hasn't distorted over the years the designers apparently did a good job of isolating the heat from the tubes. Still, I don't think I'd want to leave it on unattended on a hot day in an unairconditioned room for too long.
probably started a few house fires i bet
looks like a old drive in speaker. thanks for sharing!
That was my first impression also!
You piqued my curiosity about Moffats Ltd. so, being the Army Intel geek, I researched it and found that Crosley Radio and TV sets were sold & distributed in Canada by the Crosley Radio and TV Division of Moffats Ltd., Toronto, Ontario.
In March 1954, Donald R. Moffat was elected Executive Vice President, Avco of Canada Ltd., headquartering in Weston, Ontario; he was also the President of Moffatts Ltd., which was another Avco subsidiary.
I was going to suggest Moffatts Department Stores of Oklahoma, but your detective work is far more likely.
Great video as usual, Yes restore the case , please .
Yes, restore the case! Excellent video! Glass Slinger has some good videos on case restoration also.
Great video, Paul....watched during the storm that just passed over. :-)
Oops....yes would like to see either black/gold or red/gold.
Robot cabinet looks fine leave the battle scars, save you time for your innovations like your capacitor test.
In the UK it was common for AC/DC (transformerless) sets to have the control knobs attached to the shafts with set screws (and the set screw hole plugged with wax or resin) to reduce risk of knobs being pulled off and the user coming into direct contact with chassis mounted controls
This thing looks related to....
Rosie the robot ON The Jetsons!
You mean Rosie *ON* the Jetsons, right? (If she was 'off', then she wouldn't be on the show) :-)
Robby the Robot is the closest that I can find, yet I recall a TV robot who had a grill on the head like parallel teeth. I'm failing at my Google searches, however that's probably because I don't know what to search for LOL
@@johncoops6897 off theJensen's on The Jetsons.I think it's pretty simple what I meant. I was using text-to-speech. But I'll correct it..
I'll check out Robbie the robot.
Definitely Rosie the robot on The Jetsons!
Mr Carlson is like (but not the same) the Electronics version of Bob Ross. And I mean that in the best of ways, allowing us to actually understand what is usually a very, very dry subject.
Yep. I love how he's essentially doing the same thing over and over, but each one is a different adventure/discovery/challenge. It will never get old for me.
Gained good info on tuning of this radio.
very interesting mr carlson thank you
You are very welcome James.
Great video as always Paul. Would be very interested in the cabinet restoration please.
