I'm just a common radio, drive a common van My clock ain't got a second hand If I have my say, it gonna stay that way 'Cause high-browed radios lose their sanity And a common radio is what I'll be / shango066
Only Shango would think..."Just straighten out the horribly disintegrated line cord enough that it no longer shorts and let's figure out what's wrong with this radio..."
Blast from the past. I remember my parents getting this radio about 1953 or 54. I was about 4. It was a Sunday morning that they used it for the first time. I heard it go off and I went to their room. They were so happy because they had their coffee percolator pluged into. The radio woke my dad up for work for at least a decade.
“I don’t know what kind of Riky Dink cheap ass shit this is… But hey, it uses the tripple filter capacitor.” is going to Shangos hall of fame of great sarcastic lines 😂😂😂😂
@@shango066In the '60's, Mattel had a Glow in the Dark paint. It was thick like paste and I painted images on the cellar walls and floors to go with my 4' blacklight tube. Hey, if my Sheffield Allsport Wrist Watch with Glow in the Dark Dial didn't kill me, what would?
Hey Shango, I’m a commercial refrigeration mechanic, we use silver solder on refrigerant linesets all the time. That solder you got is 96.5 % tin, 3% silver, & 0.5% copper. The AG03 on the label is the silver content. It wets and flows nicely, but you do need the paste flux for it to work well. I’ve used 6% silver solder in my electronics projects and it does work well, but it’s a bit pricey for old radios… Great video, thanks!
I am a retired hvac-r tech. , I worked on the large chillers, constant temp refrigeration, and U.L.T. cascade freezers where a lot of times you had to braze copper to steel, needing high % silver content , that would do a great job of draining your wallet!!!!. 1 troy ounce was super expensive.
@@zulumax1google says 650 to 780 degrees. We do silver solder at my work with adjustable digital soldering irons. soldering with ours was done quickly just long enough for it to get fully wet. Our wires and terminal were pre-tined.
Sears manufacturer code 132 is Arvin. The standard E12 (10% tolerance) capacitor series is {10, 12, 15, 18, 22, 27, 33, 39, 47, 56, 68, 82} Old-school E6 (20% tolerance binning) is {10, 15, 22, 33, 47, 68} AG03 on the solder is 3% silver.
I loved watching him mess with that line cord so it would clear the short eventually , and bring power to that radio! The second I saw that cord, I knew he wasn't going to change it! Watching him plug in that broken plug made me smile inside!
I Do Cars subscriber here as well of course. Watching him tare down engines the way he does is super educational. He's taught me a ton of stuff I never knew before.
I also have been watching I Do Cars for a while now. The guy's business is right across the river from me. I friend, who is a fellow BMW fan has met him and said he's a good dude.
I still have a Silvertone vacuum tube record player in the basement that was given to me as a kid to keep me busy one summer (1977, it had been my uncle's when it was new)
When we moved off the family farm to town, we first moved into a rooming house, the old fart who owned the place loved old radios, he had one exactly like that in his kitchen, he had it wired to his electric peculator to start his morning coffee at 7:00 AM.
For the 6.8k resistor, since you have a whole bag full, you could easily just use four resistors, two sets of two each in parallel, connected in series to "make" a 1-watt.
He had his high voltage PPE nitrile gloves on, tested to 10,000 volts protecting him from fly-back transformers on TVs, asbestos and everything else known to the state of California to be hazardous.
Yeah, there are plenty of AA5 videos out there, but no where else can you get it combined with humor, bugs frying, political commentary, tin whiskers, disintegrating line cords and "this is a test" in one place. I keep coming back for more.
One factor to consider when selecting resistors is the voltage coefficient of resistance (VCR) which is normally around -200ppm/V. This means if you put 200V across a resistor its resistance will go down about 5% whilst the voltage is applied.
Those neon bulbs are what standard NE2s looked like 60 years ago. Those ‘peanut’ versions that are available now - when you can actually find any aren’t “REALLY” NE2, even if they are so labeled…
Definitely radium on the clock hands, im in the middle of trying to get a similar truetone radio working that has the same brand clock in it. I originally picked it up because it set my geiger off but now im learning a bit about old radios waiting on more parts and the manual. already swapped the tubes got it to turn on so far but no sign of any tuning as i turn the knob.
When I was 15yo in 1973, I too switched the 50C5 with a 35W4. there was a bright blue arc, the tube cracked at the base and the envelope jumped up the second i plugged it in! Only recently and through your videos am I now ready to try messing things up again!
I really enjoy the diagnostics on these old radios which are like something I might work on. I especially enjoyed the line cord with dim bulb demonstration.
I've never seen a neon lamp like that Soviet thyratron, looking down at it from the top, it looks like it would be a really cool indicator lamp. Very cool. 👍
The _"lamp"_ part is just a side effect of the thyratron action, although it was often exploited by making the end visible in the apparatus to monitor the state. This is the kind of thing that made many of the original _"blinkenlights"_ panels blink their lights.
I feel emotionally attached to tools that I use every-day. I learned how to solder on a GE soldering iron, made circa 1960s. They used a proprietary tip-heating element design that was also OEM for one of the 70s era heathkit soldering stations. Tips have been unobtanium for, IDK, 30 years now. Once the tips started getting scarce I switched to the Radioshack plug-in irons (nothing fancy like temp control) and had one in 25W, 40W, and 60W. The 40W finally kicked the bucket a year or two ago and I must have spent 20 hours online trying to find a NOS replacement because I just had to have the same tool again to feel normal and finally tracked down a Hong Kong company that HAD to have been the one supplying Radioshack for their 1990s irons because aside from the color of the handle its 100% identical in every way and even uses the same tips. With the "right" tool again, the inner peace returned... until I broke the tip on my Utica #778 needle nose pliers (their 1939 product catalog, btw, shows all the hand tools they recommended the radio repair shop have, it mysteriously lacks any nut drivers).
Yes, I love your TV and Radio resurrections but the oscilloscope episode with the bubbling capacitor was entertaining as heck and the Sony TV with the derelict zener diode was a tribute to your persistence and my favorite video so far. Thank you very much.
@@randyab9go188 ARVIN did not cut corners, it was built to SEARS specifications, and companies would beat each other up on price just to get the contract with SEARS!!!.
I have watched many people restore electronic equipment but this video is a hoot what bothers me is anyone with common sense would never plug in an old radio with a power cord in this condition execpt shango way to go youre my hero
oh hello shango, good afternoon old friend, oh shango I enjoyed seeing you fix the radio, it looked great! It worked well because you changed some electrolytics that were no longer good, and with the replacement of valves, I noticed that the operation of the radio improved a lot
"I'm just a common radio, drive a common van My clock ain't got a second hand If I have my say, it gonna stay that way 'Cause high-browed radios lose their sanity And a common radio is what I'll be" Indeed Shango! Great play on a song by John Conlee!! Well done Shango!
Comparing your circuit to a regular two IF circuit it appears the IF transformer would be the load resistance if it were a two IF design. What a great find and even more to calculate the wattage of the circuit. Smokification, another great one! All American Five radios just make us feel good. Thanks for another great video.
A friend of mine had something similar to this when I was a kid. The clock worked but the radio didn't but instead of getting the radio fixed, he plugged another radio into that outlet on the back so he would still have a radio for the alarm lol
Sir, Yes I love your TV and Radio resurections but my favorite exploritory involved that old oscilloscope with the bubbling capacitor - that was the bomb and that Sony with the derelict zener diode - I absolutely loved your persistence as that was my favorite video of all. Thanks a bunch.
I have a Philips radio-cassette with the exact same IF arrangement, except solid state. Model 22RR293, bottom of the line for 1971, medium and long wave only. I was just as surprised when I saw that the single IF stage is just two transistors, connected with a 10nF cap. There's only one AM station to receive there, weaker than the K-Mozart, so receiving it on the Philips requires a long, outdoor antenna. When I do manage to coax it into receiving something, however, audio performance is pretty good, so there's some silver lining.
Those look like Harbor Freight soldering irons. I have a few of them and they do work fairly well when new. However, the tips don't last long on them (even with your typical proper care), but they can be ground, reshaped and tinned when needed.
I live in a little town in central Ga and have all these tube am radios and most of my cars have tube am radios. There's isn't shit on anyone and I miss it. I used to have a radio on all day, one in every room and that was up untill around 2010.
I've watched I Do Cars for a while now as well. Sometimes it can be a little contrived when he says "Whaddya think we're gonna find when we open the valve cover huh?" when you know he's already seen what's under it. But I still enjoy it. My latest YT binge watching is James Condon's small engine repair channel. About 80% of the content is getting garbage, rust bucket portable generators running and putting out decent quality AC power again but there are restorations of other small engine based machines as well. He does good, methodical diagnostic and repair work a step at a time. I've put some of it to good use getting my snow blower running well...something it never did out of the box from day one.
Great video as always, thank you for taking the time to put this together! I also saw that bentley mulsan engine strip down video, youtube must be sending us the same thing! Was hoping you'd hit the bypass button to find the short in the line cord! 47uf and a 33uf in parallel will give you an easy 80uf capacitor and are both common values available today. Strange they went with something that large but probably to try and take the hum out at a cheaper price. That LA Times is anaemic! It's so sad that many of the younger tik-tok 5 second attention scrolling generation will not get the satisfaction of sitting down in the quiet with a newspaper and a drink and taking 30 mins to actually read and think about something rather than just react on impulse to a 5 second clip. The solder is 96.5 tin, 3 percent silver (AG) and 0.5 copper.
I also watch the "I Do Cars" channel. Good stuff, I watch his videos much like I watch yours. Something to watch/listen to while doing other things, and learn along the way.
Did you know: the original audio output tube for these 7-pin miniature radio radios was the 50B5. Until just a few years later, somebody noticed that if an end-user swapped the 50B5 with another tube from the radio, a serious shock hazard resulted. The tube was quickly repinned as the 50C5 which solved that problem.
the tube basing of the 50B5, and the 50C5 are not the same. I made a mistake years ago, when I grabbed a 50B5( by mistake) and put it in place that was a 50C5, and I blew out the 150 ohm cathode resistor.
I just got a pretty little bakelite-case Silvertone that this one reminded me of; has the finest in swooshy mid-century styling but with the gaudiest looking old west font on the dial.
I've been watching alot of your videos , and do get good information with lots of interesting and helpful tricks and tips . I think your approach ... while somewhat quite careless , reflects a more simplistic approach to these radios . Your hands on approach I can relate to old auto mechanics tearing into an old vintage engine or just adding gas and trying to start it . Yeah your cord thing here did show your dim bulb tester at work.
Good demonstration on how the dim bulb works.. 😂 On a more serious note.. NPR? Seriously? Radio is far from dead. But you nailed it on content. Top 40, talk, etc has made it stale and boring. I'm extremely fortunate to be in a market AND have a local station that is proud of their content and attracts listeners young and old. Their internet stream (which is CQUAM AM stereo) attracts over 7,000 hours listened every month all around the world. We just need less corporate owned, boring, predictable, and coming soon after a bailout.. agenda based programming. This is where the guys who are old school owners/ programming directors who actively listen to their public can make a difference. Not the voice tracked garbage that's out there owned by the big corporations. It obviously doesn't work as one is already going bankrupt. Great vid btw!
Hopefully I come across someday, I really wanna visit that tube collection. If I learn how to properly service this old stuff I may do the same at some point.
@17:50 - If you ever think your content is the average recapping pablum, you're sadly mistaken. I don't even do this kind of repair, but in this day and age of short attention spans, I can dig in to well over an hour of your content and not once switch windows in the middle of it. I sit for the entire program minus commenting time. Never change the way you do things.
Everything in my grandparent's house was Sears, JC Penney, or Kmart. I don't think any of them exist now. And yes, I watch I Do Cars just for the entertainment.
Technically, they all do- JC Penney has 663 stores, Sears has 13 in the US (plus Sears Mexico has another 92), and Kmart has 6 left in the US and territories (and Kmart Australia has another 325 in Australia and New Zealand)
I've got a real nice Craftsman iron from the 70s. I have to use it anytime I run into a PCB with a large ground plane. It puts the Pinecil to shame. However, it also weighs about 10x as much. 😂
I can't believe you plugged that ratty cord in! NPR news is quite informative. It look like the 22Ω resistor was reading 219K on your meter; plus ALL the wax CAPs need to go. 50C5 always run super hot! It's also BAD!
It never occurred to me that you could use a dim bulb to protect against one of these cords. I, however, will continue immediately replacing them before I do anything else.
