repairing an old radio mpeg2video

[@sr633]

Watched it all and enjoyed it. Now I have a few good questions to ask an old time radio and TV repairman who I admire so much. Thanks. You solder like a champ !

[@terryhall7177]

I've been watching your videos for a while and I'm learning with every new one you post. You're a great instructor! I joined the Navy in 1963 and went through sonar school in Key West Fla. when I was 17. As part of our training we had to put together a radio with parts that had been soldered then un-soldered many times, (readied for the next class) and we were lucky if we could pick up a station out of Miami but most could pick up Havana. We learned the basics. I've started watching your old videos and this one was very interesting and informative and I have to keep stopping it and making notes. Some are just general tips you give as your working and some I've scribbled on the schematic of my current project but all are very informative. Thank you so much for educating all of us who are eager to learn and please keep uploading more.

I have a friend who is an expert in rebuilding vacuum tubes in his barn converted to laboratory. It is an amazing operation and all the fellas have lots of experience in the field. I took a course in radio repair long ago and was able to follow the video. Very well done. Thanks.

[@ericlees7518]

great insight of a radio repair thank you from the usa to a uk radio man hope you are still going strong not many of us left now

[@jeffmitchell9214]

Such a pleasure to watch a master working. You younger people realize that these guys are who taught us back in the day, I love how he whips that 100 watt Weller soldering gun around. Lots of experience here.

[@brianbloom1799]

Ron Ever since you Told me about the CRC Brakleen, I am Amazed how well It works cleaning switches, Thank you.

[@nor4277]

I have learn a great deal from you,also I never seen anyone solder as fast as you with that big old soldering gun,or the speed you solve problems .I Been solder well over 40 years but you are so much faster than anyone I have ever seen.I will keep watching you and maybe if I am lucky buy a tube radio from you I like the sound better

[@robsilver7780]

Awesome Video! It takes away some of the mystery of radio repair. Thanks a ton!

[@judges69]

Thanks, I learn lots from your videos. You no more then I will ever no

[@broadwaygeorge128]

I learned so much from this. You are very skilled and should be selling instructional videos and writing books. I liked how you used the signal generator. Maybe a video on the uses of a signal generator?? Thanks Again.

[@olenamcquagge7777]

Man...I felt like I did the repair with you...Nice Job!

[@Romenadan]

Excellent work! I recently went to repair a 1928 Victrola Radiola but unfortunately found that the interstage tuning coils had shorted out and the variable air caps were destroyed. Amazingly none of the bias and linkage caps were bad. I replaced all but the power supply electrolytics anyway. I ended up scrapping the RF front end and just remaking it into a mono amplifier since it was a lost cause to try to repair. Works great aside from loud 60Hz hum.

[@THEMICROMARKSHOW]

i love your videos...they really relax me and I get some great tips.

[@oldmaine4314]

Thank you! Best advice I’ve heard in a long time regarding repairing a customer’s vintage electronics 08:23

[@ZeedijkMike]

That hour just flew away. Very enjoyable video. Nice trick to hide the new caps in the old housing. Just got my first 'oldish' radio a few weeks ago. It is from the 1970'ies though so no tubes 😐, but it is a good starters project for me.

[@themainproblem]

This was a great video! Nicely done. Back in 2006 or so I restored 4 Heathkit HW-30 2 meter AM transceivers but I shotgunned them all. Including teflon wire for interconnections, and all new carbon film resistors. Results were excellent but my reasoning for doing that was that I thought since all the components were getting very old the radio would be a non-stop maintenance headache if I didn't. The radios work perfectly now.

[@stephenbrookes7268]

Whoever you are Glasslinger can I come and spend a few months learning some of your stuff please! I have worked on a few old radios and radiograms from the 30s+ 40s including a Marconi 2 valve set. I know when the old engineers die so will the skills that they have. I want to preserve these skills.

[@realvanman1]

Very nice, it's always a pleasure watching and learning from your videos. One of the things I always look for when buying old electrical stuff is a good original line cord though. So long as they're in good condition and not handled roughly they serve just fine. I'd have left that asbestos in there too :)

[@brianamyotte3866]

I learn from every video you post - thankyou

[@ruciprawitasari9107]

great job... and I do enjoy your nice videos, thank you

[@NOMOREPAM]

If I just had watched your videos 20 years ago. My uncle had an Admiral 'Transoceanic' 1960's tube radio. I barely understood what it did. I think he got the radio as a payment from a traveler visiting the port. Please keep posting more videos sys.

Nice job on the restoration Ron! Also thanks for the explanation on fuse specifications. I always thought a 1/2A fuse would blow there at 1/2A. I didn't know it would take a 1/2A continuously and only blow when reached approx 50% higher current value. Tom

[@muddysledge]

Nice. I noticed you don't worry about "J hooking" the new components and don't seem to have any issues. Saves time not to have to do that. I suppose having a hot enough soldering gun helps. I have a Weller too. Good dependable guns.

[@loricastro3772]

Whata kind of tape are you using in 43:36 to isolate the back of potentiometer?

[@glasslinger]

It is kapton tape. (a brand of mylar) You can get it on ebay for cheap.

[@richardmcleod5967]

I wonder if that Beitman's book has a schematic for a Herbert H. Horn Tiffany Tone Model 73 C ( a small medium console radio made probably around 1937 or so) radio? It does have a magic green eye and a very impressive Dial Face design with a glass cover instead of plastic. I am in need of such for the repair of my radio as it hasn't been played for many years. The veneer needs some help but the cabinet is in fairly good shape and amazingly the original grill cloth appears like it is new with no tears or stains on the cloth. This is a rare radio and one that is not even listed in the radiomuseum site listings for Tiffany Tone radios.

[@greggaieck4119]

WHAT A KOOL. OLD RADI0 RECEIVED

[@sheep1ewe]

I was thinking about this vide when i red about another project when a guy built in a RaspberryPie micro PC card in an old radio chassi. This must bee the ideal combination, one needs only the intestines and another, like most people (at least here in my country) wants only the chassi and other visible parts to fill with modern tecnic. It´s good to see that there is still people who salvage even the intestines in thos old radios in working condition. Personally i concidering about building a replica of the chassi so i had to re watching this video again for inspiration! Since i want the same feeling as the original (but i dont vant to destroy real items of historical interst.).

[@sheep1ewe]

Nothing beats to hear the original sounds from an orignal apparat like this!

[@theedrstrangelove]

I try to use the old caps like you say here when I cap the guitar amps I work on. It really keeps the original look.

[@markhodgson2348]

It's so good to see no advertising on your videos

[@Calling321]

What types of tubes are those and what do they do? Do newer radios have tubes?

[@IamTheSherm]

Vacuum tubes were replaced by transistors.

[@freesaxon6835]

edieken7 really? You in combat gear and ..... Him in a dress?

[@bones007able]

You apparently have done this for years....I read some comments on here on how you are being rough with the parts, but most of the hobbyist today do this for fun, and not for a living... back in the day a repairman would make 10 calls a day and would do exactly what you do in the video, you must of worked in the field doing this stuff... I remember our TV repairman came out to replace the power switch on TV... he threw parts and tubes around and into his tube case and thought nothing of it... Nice video!

[@ritchiepitchie8839]

Thanks!!! It's a Zenith 10-S-153. All five knobs are missing. Can you help me with that? Also, theold cloth covered power cord is a dry, rotted and frayes. I'd like to start there and see if I can get it fired up. Thanks again for your time!!!

[@glasslinger]

You can get the cloth covered wire on ebay under lamp cord. Be sure to do some work on the radio before plugging it in to keep from burning up stuff! Zeniths are bad for capacitors, you probably will have to replace all of them.

[@joshuafitzgerald5442]

For cloth covered wire I'd recommend Sundial Wire since their stuff is made entirely in the USA, which is very important to me and I'm sure many others.

[@SOLARISSOL1]

repair vs restore is a big difference.

[@stevesalinas9508]

Those old caps are usually covered/sealed with beeswax. You can sit it in a tin in the oven and heat it till the beeswax runs and wipe it off the paper to read the value. I do that and rebuild/repack the cap with new cap and fill with beeswax to look like the original.

so, just wondering why you were drilling into the new volume control? Were you making an access to shoot in some contact cleaner?

I work on commercial radio gear and I have piles of old tube type 2-way radios in my storage. Most all of them work fine while others are DOA.

[@tonipepperoni3424]

old man but it does make it interesting to have an old radio and fix it hear newer music on it, its like a strange occurrence to see something old have such a direct contact with something new

[@jansramek2867]

great renovations, you can look at my renovation kzbin.info/www/bejne/qYLKZ6Odh66cnJI

[@chetpomeroy1399]

That doesn't appear to be a AA5 radio, as I don't think they started making them until the mid-40's or so. I suspect that the tube filaments are wired in parallel, hooked up to that transformer. Looks like you've done this a few times, as you make it look this task look so easy! I am aware that radios of that era often didn't have the standard 455 kHz IF. Excellent video, thanks for sharing!

[@Super8Rescue]

Really enjoyed watching

I didn't understood what you said at 16:16 about the 'two types' of radios needing or not needing fuses. I mean, one is a transformer radio that needs a fuse. But.. What is the other? I'm sorry but I didn't understood. English isn't my mother tongue and I'm new to all of this.

[@toserveman1496]

most radios of the forties to the fifties, did not have an isolation transformer. That meant that one part of the power cord went right to the chassis, it was called a hot chassis which would electrocute you if you touched it and you were grounded. That was one of the main reasons that they came out with polarized plugs

[@jonsnell4751]

A lot of older British Radio and TV sets used brass screws and I used to save my bees wax capacitors to use the wax on the end of my screwdriver to help remove and refit them. I still have my AVO 160 valve tester.

[@AndrewBryantPianoTuner]

Bloody excellent video!

[@markbell9742]

Hi: What’s your thought on polarized plugs and/or adding a ground to the chassis on radios and other electronic equipment of this era. Cheers, Mark

[@captainkaveh1]

you are very professional..

[@fernandoburgos562]

Greetings Would like to know if in order to calibrate a RCA Model 6K2 is necessary a Oscilloscope. Having problems with getting the radio stations

[@glasslinger]

A scope is not necessary but is helpful. A signal generator is necessary. First check the antenna input coil. These are common to be burned out. Then start with the audio stages, injecting a signal to the grid of the first audio stage. Then the grid of the I.F. stage, use a 460khz modulated signal. Each stage towards the front end should give a vastly greater volume.

[@robinroeckers8149]

Where did you get your tube clamp?

[@barnagy]

Nice work. :-)

[@americafirst9301]

A cloth cord is pretty and all that other stuff, but a polarized plug leading to ground on the chassis would have been a safer setup

[@gregorgman]

tell us where you hook up the generator and is it RF, Audio, what?

[@truthtoad]

I've got an old radio that I'm repairing. Thanks for your help. I'll let you know how it goes. The case is broken so I'll probably build a plexiglass box to show off the tubes.

[@blink-klippie]

I enjoyed the video very much thank you. Great hints and tips for troubleshooting. Very useful. Curious what the next video will be about. Kind regards Paul.

[@helipilot727]

Great video thanks for sharing

[@koldenrjk]

It looks like you left the old electrolytics in there - is that true? Are they hard to remove?

[@glasslinger]

Sometimes they are left in the radio to preserve original looks. They are disconnected electrically.

[@helipilot727]

I would recommend non-chlorinated brake cleaner... it does not attack plastics. The others (and carb cleaners) usually contain acetone.

[@glasslinger]

Best to test a drop in an inconspicuous place first. The red can CRC brake spray seems to be compatible with all but polystyrene.

[@danielletendre9439]

Very good video, well explain.

[@briansmith2363]

glasslinger I got a old early 40s Zenith 66501m am radio only one tube lights up. What could be wrong with it that could cause only one tube to light? Is there a way I can check the radio with a multi meter to see what is wrong with it? I have a schematic for it. also will a schematic tell me which side of capacitors are positive and negative?

[@glasslinger]

you can use the multimeter to test the filaments of the tubes. Read between pins 2 and 7 for continuity on the X10 ohms scale. Count clockwise from the alignment ridge on the center post. The old diagrams were drawn with the negative end of the filter capacitors towards the bottom of the page.

[@525Lines]

I thought tubes went out. Do TV tubes get burnt out or is replacing easier than cleaning? It used to be a small business for kids to strip junked TV sets of tubes and resell them.

[@nobody-429]

+525Lines It is not necessary to replace a tube unless it's blown out, weak, leaky, or missing parts (e.g, glass or plates)

[@interestingstuff-ag1890]

nice video. Question, why not go to a 3 prong cord, and have a ground on the power cord to chassis ground?

[@octavioramirez60]

Hope you never do that, one of the line cords goes to ground (the chasis) and you may end up connecting the live line to ground

[@Elfnetdesigns]

Octavio Ramirez You can connect a grounded cord to these old radios if you know what your doing. reason people do not do this is because they want to maintain the original look the radio had. A 3 prong grounded cord is not original. To do this mod is up to the person owning the unit vs. the repair tech servicing it IF they know how to do it, You can even go as far to add in circuit breakers instead of a fuse and MOV's.

I get all my caps from Mouser. Note that they have a $12 minimum shipping charge so you need to buy a batch of capacitors to keep the shipping reasonable. Buy a small amount and you can end up with the shipping being half the cost!

[@ivanigorpollick6690]

you are extremly good in repairing..

[@MrMac5150]

You should twist your connections together before soldering.

[@donaldwallace7934]

I noticed he does not make any kind of a "mechanical" connection with the components before soldering them! Very bad practice in my opinion, as one should never totally depend on the solder to hold components securely. I was taught to use a "J" hook configuration, so the joint can be crimped before soldering. To each their own I guess.....But, definitely not the way I do it !!

[@scharkalvin]

sheet asbestos is usually stable. The type that is blown in as insulation is dangerous when it gets old. If it was me, I'd find a place to mount a fuse holder in the radio rather than soldering the fuse in.
