Rookie Radio and Television Repair
США
Добавлен 25 дек 2021
This is where I upload videos of my progress in learning vintage electronics from scratch. I am completely new to tube radios and televisions. This is also where I post videos for the people who are helping me diagnose my projects' problems or answer my questions. I am learning how to spot and change defective components. My knowledge is greatly lacking in being able to look at a schematic and tell someone how the circuit works. As far as it should be reading such and such at pin so and so... that is where I am at today. I hope to understand the complete functions of each part of the circuits as my knowledge advances. I will be learning on AM tube radios and hope to be able to repair my 1940s and 50s Televisions when I am ready.
Drowning in Zeniths!
I got a little carried away on the radio auctions. They sure are fun! Now I have to do the work. Time to fix and list these, not nearly as fun as buying them!

This radio is going up for sale but needed some work. In this video I replace the speaker cone. This is the first one I have ever done. I watched a nice video from Uncle Doug to get some inspiration to try this myself. I tried finding a 3 ohm speaker that would work. I had no luck.

I was given this record player back, that I had given my dad a few years ago. I wanted to be able to use it to play the records that my parents had enjoyed for years. I found a pair of speakers on the cheap, just to see if the stereo amp worked. I can load a big stack of records on this and play for a couple of hours. I don't do the audiophile thing, one at a time. All the records have a ton of...

This radio was restored by someone who made a business out of doing it. Not sure how long ago. Then it ended up in a thrift store, where I acquired it. It came with a very nice info packet put together buy the restoration business. They left some original capacitors in it. I have noticed this trend alot when looking at radios that were previously worked on. I have yet to find one where they bla...

I picked up more inventory for my antique flipping side hustle, but the more I work on it the more I think I'm going to keep it! I have nothing like it in my collection. It is a very early marriage of a mechanical phonograph with a battery operated radio. Really neat and strange! The early stuff always excites me. I will put the intro video on this radio channel and on my phonograph channel. I ...

Loveeeee this stuff
I wonder if there is a way for me to contact you via e-mail about this jukebox. I am working on a 1937 Seeburg Rex that has an amplifier that is identical to the one you picked up as a possible replacement: SB10200 Mine works but I wouldn't mind having a spare on hand if you didn't use yours and it could be acquired for a decent price. Thanks! Rich
Awesome looking bookmatched sides radio. Packard Bell did this to a couple of other models like a later 5AE, 5D-DL, 88, 551 and 566. There were more I'm sure but this kind of unique wood back design stopped around 1948. The secret to the design is the chassis gets removed from the cabinet from underneath after removing the knobs.
A very good looking set !
Glasslinger I seen him restore cabinets
Lot's of people do.
This might be a farm radio 📻 . They used a 90 volt battery 🔋 system. That speaker 🔊 is not original. Merry Christmas 🎅 🎄 and a very safe and Happy New Year to ya!! Your friend, Jeff!!
90% of YT radio repair creators can't seem to understand how loud the sets are compared to narration on camera. And then they try to talk at the sane time. Not a bad video except for that.
It's hard to judge. I try to get my lips as close to the mic on the camera as possible. I will see if I can hook a lapel mic to it.
You were right when you said that they stuck the one that they had in there. You should go back to the 12, the rectifier will be over worked by the larger cap.
Ok, I'll pull it out when I get home from work today. Thanks for keeping an eye on me!
You need glasses bad.
@@Thomas-yr9ln 😎
Nice! Subscribed.
Thanks!
Great job and thanks for the mention of Uncle Doug. I will watch that. In the meantime, is there a link to the sale? I'm interested.
Thanks for your interest! I posted the link in the description to Uncle Doug's video. I also sent you an email of the Ebay listing. By the way, I checked out your channel and subscribed. I will be watching your videos for tips when I get ready to replace some veneer on and 1890's music box that I wish to restore. 🙂
i got same speaker did you figure out the needed transformer? i have a variac, will that work to power this? thank you
It takes 6 volts so I bought a very small maintenance free lead acid battery and just recharge it with my power supply when I'm done playing the radio. I think I bought it on ebay.
@@electricalmagicsmoke i have the same one in the video. my terminals don't have + or -? looking from the back which is which? thank you
@theuserthatishere it's just a coil of wire. So you can run it either way. If you can notice a difference in sound quality just run it that way. At worst the speaker would be sucking into instead of blowing out. I have measured hearing loss and ringing in my ears from my time as an aircraft mechanic and can't tell the difference.
@@electricalmagicsmoke i meant the 6v dc
Looks like that was a good auction buy on the tubes. Since you only do radios and they are all old radio tubes. The Bendix is a 646A and the whole top drawer is faux wood over glass but in the center was left unpainted to show the dial which seems to be missing. Centered below that was the name Bendix. A rare radio for sure. the Philco is a model 60-MB from 1934. The model 60 had many changes cabinet style wise. You have a Zenith radio phonograph model 6-R-886, nice!
Thanks! Being that I am still learning I like the early stuff as a beginner as it is typically simpler and easier to understand. Some of the veteran radio club members have magnificent, rare, and technically significant sets that I can't yet begin to understand. I hope to get an appreciation for them as my knowledge grows. Also the early radios, not counting the tubes, can be bought at very reasonable prices. Perfect for entry in the hobby. Some of the members have radios that I would not be able to sell enough blood to buy! 😂 Spartan mirror model, Scott with the chrome guts on the outside of the cabinet, etc...
@@electricalmagicsmoke I have only been doing restorations and the like on vintage stuff like this for 4 years. Thank you internet; it is a Godsend of information but it takes time to find places where you can learn stuff from or buy it at a good price.
Used to like these turntables. Or as I called it, when I was young, a record player.
That's a beauty!
Get a new turntable. This one has horrible warble and flutter. The bass line was not as tight and firm as it should be with good playback. Find either a good used turntable like a Technics or buy a new Fluance.

Just found your channel. If I may offer a word of advice, use the "one hand rule". Keep your free hand away from the chassis or other grounded surface. Should you inadvertently touch a hot terminal strip or socket the B+ voltage will flow right through your chest. From experience I know that 250 or more DC volts is quite unpleasant. There is also line current ahead of the power transformer to be wary of. When in doubt about a component check the schematic diagram. Since in tube sets almost every component ties to a tube socket it is not too hard to determine the purpose of the device. A 3rd bit of wisdom: Get yourself a receiving tube manual, it will show the approximate voltages present at every tube pin. Have fun with this hobby, but be careful!
@@don1857 Thank you so much for the words of wisdom 🫡
I got a postwar RCA Victor #RC1064B274 that looks so similar to this. Need to take it to a shop to repair the dial, I still get sound out of whatever AM frequency it is stuck on. Great video!
Definitely recap before it takes out something you may regret.
@terryblackman6217 If I keep it, I definitely will 👍
I just bought that tv on impulse today! Looking forward to some learning!
Hell ya! Jump in with both feet brother! Can only learn by doing 😆
My suggestion is that you leave this for someone more qualified before you damage more of this antique. Unqualified "restoration" is worse than none at all.
@user-qv9oo2co7t So how does one become qualified without doing something to learn? I belong to an antique radio club and get plenty of guidance from old pros. I have quite a few repairs under my belt and have 18 years of electrical experience on multimillion dollar aircraft. I am confident I won't hurt it. I suggest you let people learn, or there won't be anyone left alive to work on these. The average age of the guys in the club is over 76. They are wanting their craft to continue after they are gone. Also, this unit was headed for the dump until I saved it. So I strongly disagree with you and say that this unit is better for me having saved it and will be working on it. This isn't a Picasso. Thanks
The 120 should be plugged into the third socket from the right. The far left socket gets a 199.
Ok thanks! I guess I should pull up a diagram for this now. You wouldn't happen to have a source for the UX120 by chance would you?
You'll find that the 6499 tube is even stranger than you thought. If I read the number right, it's an early digital memory device based on the same physics Tektronix used for the storage oscilloscope tubes.
Ya I looked it up and never heard of such a thing. There is a collector of early computer stuff in the radio club I belong to, so I made sure it went to him. Someone that can truly appreciate it. I did not open the box. I will let him have the honor 😅
Wow what a beauty
Right now on my bench is the horizontal/high voltage chassis from an RCA Berkshire Regency projection "entertainment center" from 1948 that was owned by an RCA service tech for many years. We at our museum are lucky to have a parts set for needed components to contribute to the restoration of the Regency. The TV componnents are identical to all RCA projection sets from 1946-1948, however the radio system is radically different from the usual production models. A nine band mororized tuner chassis and a 40 watt RMS power amp/power supply chassis is included on the Berkshire lineup along with a 15 inch full range speaker. It is a monster ! Hope to have it all operational in September for our swap meet so it can enjoyed by our visitors. I would love yo know of uour progress worh your RCA projection set ! More info on the Nerkshire Series is availble at the Early Television Foundation site. 😊 Our museum is at vrcmct.org
Beautiful TV. Just be careful, that sumbitch will bite you if you're not careful in the HV power supply
New old stock? Oh lets not put the screws back in... sounds sketchy at best. I tend to not believe anyone anymore because , lies , lies , lies...
The screws were removed by the last owner. Who died. We took a bunch of his projects to auction. Either way, the condition of the unit is remarkable. It makes no difference to me. I get a very nice starting point weather it was new old stock or not.
You are like my dad's cousin James. He has his house so full of radios and vintage TVs you have to walk down a narrow path through his house.
Well I'm not that bad yet, but I'm working on it! 😆
This is the home version projection TV that Bob Anderson has with his being a 741PCS . They all have the same electronics namely the Projection Television Unit PTU-1. The Howard SAMs can be found on the internet. I think there are some higher than usual voltage rating electrolytics in the power supply that must be replaced first before going any further on it. Great scores on some cool stuff!
Thanks so much for the info! Bob was kind enough to respond to my email and sent me links to his TV on Patreon. His TV is even bigger than this one! A behemoth! He warned that this one puts out 30,000 volts. So I will take great care.
The 'lytics in the horizontal sweep chassis are rated at 70 mf at 400 volts, and are connected in series for the pi-network input of the filter system. I am using 68 @ 450 radials and restuffing the cans to preserve the look, and also because there isn't much space underneath to install large axial caps.
Well I have to admit it's the strangest TV I have ever seen. Love the radios. Well done.
Good find. At the end you could have a beautiful functioning work of art from the 1940s.
One thing I like to do is power the set up with the rectifier tube out of socket first (in a parallel heater configuration of course). This will ensure the power transformer and heater circuits are functioning before cranking up the B+ voltage. Great choice of music for this vintage radio!
Two words come to mind. Jim. Burns. He worked on several of these Zeniths and knows all and does tell you how to do restorations on old prewar radios on his channel. I have a Silvertone 6071 with two frozen knobs; one is the volume on/off switch the other is a 2 position selector switch. Tried heating the shaft near the chassis with them loose from the chassis and using WD40 to no success. Guess they must be removed out of the chassis to fix.😑 Check out Jim's wonderful channel!
Sure thing! I actually just found his channel yesterday. I just subscribed.😀. He goes way more in depth than I can. He does ground up restorations. I have to watch my labor time so I don't go upside-down on the cost of the flip.
@@electricalmagicsmoke Baby steps, but this is how I learned about old electronics repairing as it was something my grandfather did when I was a teen. Jim makes money on nearly all his restorations BTW.
@@hestheMaster I need to clear $1000 profit a week on all Ebay sales. So I will be selling cylinder players and any item I can flip. I won't be able to quit my job on just radios. They take a lot of time. I hope to be able to quit a job I dislike and stand on my own by the end of summer.
@@electricalmagicsmoke Wow. You remind me of another guy in his early 60's who does vintage stereo repairs and does have his own channel. Look for Steve Scarlet. Very impressed by his work.
Ok, so which is it? Did you pick it at a thrift store or did you purchase it via mail?
I restored a 6 S 223 a while back works great, had to replace the pentagrid tube. I did a 1941 Philco console for my sister, was a big pain in the butt, it has the gutta percha wiring and loctal tubes that had corroded pins. I didn't try to replace the wiring, just made sure it was all separated, added a line fuse. Never again
Great looking radio. I'm glad it arrived undamaged from the seller. It's a huge risk to put these old fellas and gals in the mail. Restore it and good luck!
I did one of these sets on my channel. For 1942 Zenith used a lot of rubber wiring - most of mine had to be replaced, including to the tone controls on the front. They also use a 6X5 rectifier which is prone to shorts and can take out the power transformer. I generally replace this with a diode and dropping resistor to get the B+ voltage right. Once these are restored properly they're very nice playing sets.
Thank you so much for the info! I went and subscribed to your channel. I am always looking for resources in my vintage electronic education journey.
A good looking example. When you have a chance, clean all of the tube pins, loctals can have oxidized pins, and give you headaches....
Sure will, I hope this radio doesn't put up to much of a fight.
The turntable set up is definitely an admiral. It is the exact same one that was in my 1940s admiral radio record player floor model. Had it 50 years ago when I was a teenager. Bought it at a garage sale for probably 5 or 10 dollars
Love your Lincoln. I remember as a kid in the 60's the Civil defence markings. My dad had those in his 63 Pontiac Bonneville. The one you have in your classic with the tube sound must be amazing to listen to. We need am radio back with good old music. Thanks for sharing. 😊
Hi, I have not been able to locate a schematic for this Emerson. Liked your video. Thanks
I would venture to guess it has capacitors that are degraded and get worse with heat. They may have been replaced long ago or never at all. The key symptom is it changes with heat. While it is a TRF set, it does have the "new" AVC circuit Philco introduced in that chassis. The AVC would sit on the gain of the various stages depending upon if it was a low power signal or high power signal. If it is running away with volume and the station and power hasn't changed, it's definitely in the AVC circuit.
Thank you so much for the comment! I will check it out.
Is the radio a superheterodyne or tuned radio frequency receiver?
It is a tuned radio frequency receiver "regeneration unknown" from what I could find on it at the antique radio museum.
