Why don't you install small cooling fans in some of these tube radio's?

[@davelister796]

Would like to see the case restoration. I vote for red and gold. Curious What type of vintage equivalent paint you'll use.

[@michaelshultz2540]

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.

[@AmitKY108]

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.

[@NigelDixon1952]

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 KZbin channel, Paul. You have a world wide audience eagerly awaiting your next knowledge packed video.

[@nelsoncoffie5668]

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.

[@5cloudwalker]

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

[@projectartichoke]

Just have to complement you for having perfect audio levels on all of your videos. It's a rare thing on KZbin.

[@MrCarlsonsLab]

Thanks for noticing! I work hard to keep it that way.

[@Digital-Dan]

Also a camera that stays in focus at all zoom levels.

[@deadfreightwest5956]

@@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.

[@deadfreightwest5956]

@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.

[@MrCarlsonsLab]

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.

[@fb341]

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. Frank B+

[@DavidTipton101]

Thanks Paul for another instructional video. I get lots of info from KZbin 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) 🙄

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.

[@hestheMaster]

@ 52:10 you mentioned that the components in the chassis don't match up with the schematic. Boy have you got that right. Noticed you correctly placed a third electrolytic on it at the cathode of the 50L6 tube . 10uF at 25 Volts. The two section electrolytic is supposed to be a 30uF and a 50uF at 150 Volts each. Glad you have the ability to reverse engineer the design of the radio for it's poor performance issues and was able to correct them. Great radio for those cold winter nights because it doubles as a hand warmer as well! LOL

[@sincerelyyours7538]

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.

[@parteibonza]

probably started a few house fires i bet

[@NikolausSchmitt]

I really enjoy your explanations and restorations. Next time I stumble across an old radio I even might get to try a restauration project myself. Meanwhile I found an 1948 Farviprüfer (tube tester) with programming cards at my uncles old house. Have no real use for it - any interest?

[@alterschwede1914]

I'm just a little surprised ... Because in Germany all AM transmitters in the radio band have long been switched off. By the way, I was trained at the former Grundig company and later worked at the Satellite World Receiver. But that is a completely different number. That's not " that easy " :-) But anyway, I like your videos. Keep it up

[@zopilotesky3014]

Nice looking radio. Definitely paint it one of the factory color options.

[@MrPatdeeee]

Very well done kind Sir. I surely would have loved to have your capacitor checker when I was a technician. For when I was repairing radios in the 50's, the ONLY capacitor checker was our ohmmeters. And you KNOW how inaccurate that is. Not to mention checking electrolytic capacitors. Oh well. Question. Do you calibrate your Signal Generators? If yes what is your reference. Thanks. Love your channel. (Note: I see an RCA 3" oscilloscope on one of your shelves. That was also available as a kit at one time. So I built one and I still have it. I imagine all the caps, some resistors and tubes are bad now. I haven't used it in over 60 yrs.)

[@MrCarlsonsLab]

Hi Pat. I have a reference that's calibrated by the WWVB. Thanks for your kind comment.

[@parteibonza]

My shop teacher told us about how this air force mechanic tried to climb on top of a huge 50 year old capacitor to grab something above and it still had a charge and it burned him to a crisp. pretty much blew him up. I learned don't mess around with old electronics!

[@dave1135]

The tag on the bottom could be right. I worked at a Goodyear tire shop and our manager sold crosley tv's, washer and dryers, phonographs, etc. I had bought a washer and dryer set, and when it needed service, the washer was actually a Maytag that was branded as a crosley, so I guess they did things similar to Sears with their craftsman line

[@lelandclayton5462]

These days Maytag is Whirlpool.

[@ronniepirtlejr2606]

I did something similar on a 1976 Panasonic radio. The string was broke. I was looking for the old time fishing line from the 1970s but could not find any! I ended up using 65 lb. spiderwire. It worked but, it's a little thin & still not what I was looking for. I doubt it's going to break! Lol

[@leonardpeters3266]

That radio reminds me of a 1961 Thunderbird, it has a beauty to it's ugliness. I do allot of restoration to wooden radios that have been damaged too badly to ignore. I find it very time consuming but rewarding. I must admit when it comes to Bakelite, I just try to find them in good shape and polish them. I can see where the right paint job properly buffed would look great on that radio. Go for it.

[@JamesHalfHorse]

That cleaned up really nice. I am wanting to restore on a classic AM radio for my station I am now by default the chief engineer of with the now nice new solid state AM transmitter dumping a gallon into an 80 year old shunt fed tower with 80 year old grounds you can guess the noise I have to deal with. RF eats up everything solid state especially radios and I would wager a good quiet build like this and some of the radios I have seen you do I would bet it would shrug off the RF. Now I just need to get on your patreon and build some of those testers. I am betting the old time gospel format on said station would sound awesome through an old time tube radio.

[@jake2213b]

I have read that Crosley made his radios to sell cheap because he had a radio station that at one time was 500,000 watts. It was funny that when you were tuning that radio you put it on 700 which was his were you could find his radio station. Today it is just 50,000 and is WLW. You can see it from I 75 north of Cincinnati as you go to the Dayton Hamfest. You can take tours to see what was his 500,000 transmitter.

[@TBizzell68]

I’d really love to own a nice tube am radio, I’ve looked on eBay. Most aren’t restored and even though I’ve watched quite a few of your restorations I would never trust myself to restore it. I wish I had the three or four radios that I dismantled in my childhood.

[@waynethompson8416]

Paul, Very good video! As always an excellent "training video" and very much enjoyable to watch. I hope more people will join your Patreon account, there is so much for them to see that is only available to Patreons. I found myself wondering if you could hear me through the internet...I would say something like "Please change that part", or "show this" or "explain that" and right on queue, you did it! I guess it is just a matter of we think a lot alike on some things. I, and I am sure many others, would very much appreciate a "corrected schematic" for that set. Showing original and added parts for the design. I know you are very, very busy with all the other stuff you are doing, but we would appreciate it! Concerning the case...by all means...PLEASE do work on the case, and at least show us the final product if not the entire process. Thanks again for sharing these wonderful videos with us!

I've been spending some time going back over some of your older videos. I have one of the Precision Apparatus rf generators you are using. While doing an alignment, I can listen to the 400 Hz modulation tone all day and not find it annoying. Maybe I am used to it. The aircraft carrier I was stationed in had 480 volt 400 Hz 3-phase transformer banks powering various shipboard electronic systems. With loose laminations, these transformers would scream! I have an newer solid state rf generator that utilizes 1000 Hz modulation. I find 1000 Hz very annoying!!

[@deadfreightwest5956]

55:25 - I once had a spool of General Cement dial cord that belonged to my dad, but like most things, it has gone to the island of misfit toys. I'm slowly acquiring the Heathkit test equipment he once had over 60 years ago. I love looking through the old Radio-Electronic Masters at all the products and gleaning info from them. I have a Triplett wattmeter but have no idea how to hook it up. Have you ever used Quietrol (sp?). I remember that stuff from way back. Super thin, red, very distinctive smell. Apparently mostly carbon-tet and oil. Sure worked a trick on pots and switches! As you point out, people smoked back then, and my dad smoked like a chimney. Still, doing a brake job on the car, he'd warn me not to breath the dust. He said this with a Tareyton cigarette in his mouth, just before he'd blow out all the dust with compressed air. He'd even check the battery while smoking, lol.

[@suaspont]

I noted that you were using a watt meter with fuses as your "current limited' supply. Ever since I was a youngster (about 60 years ago), I've used a incandescent light bulb in series with the hot lead. That way, even a dead short would simply light the bulb. Over the years, I have developed the skill to watch the bulb as a diagnostic tool - inrush current, filaments heating up, etc. I always use an isolation transformer and variac to slowly bring up the device. Is the light bulb still good practice, or is there something better?

My thoughts on the poor venting and the radio getting hot is ....... Back then people listened to the news , or 1 or 2 radio shows on their radios...... Those radios weren't turned on for hours and hours like we do today..... That's just my opinion though.... I was raised up in the early 60's and my family watched only a couple hours of TV each day.....

[@MrLeejan]

Powell Crowley would take a newly designed radio into a small room and cut parts out of the chassis. If the radio quit playing he would put it back.after he had removed all unneeded parts . He would give it to production to produce like he had left it.

[@micametalgem3721]

I have heard the same thing said of "mad man" Muntz of Muntz TVs.

Crosley, aside from the very beginnings of the brand, has always been a budget brand traded around by various manufacturers. Currently the brand seems to be owned by the same people who now own the "Victrola" mark, and the brand is applied to subpar portable record players.
