At 22:00 you more or les gave up on it for obvious reasons. Then I looked at the remaining time on the video and then I knew that you would get it to work again, and you did!! Thank you for the upload!
You always amaze me! Thanks. Like entering the twilight zone. At first the voltages are bad, later okay! Your reasoning of why the voltages are off by following the flow, you mentioned it at least twice really helps us visualize the operation of the circuit. Keep em coming!
We have the gradma's singer sewing machine in excellent condition that bought in 1934 along with its payment bills.And thought that might get value as a vintage machine until i found that ebay sells brand new replacement parts because there are million machines outhere.Also the same and even worst with my Amstrad CPC464,so the vintaging occupation is not my lucky area.
There used to be a deal that someone would bring me a broken computer, typewriter or even radio. I would tinker with them a bit and usually they would start working. I usually never knew what the hell fixed them, and it soon became known as the "Chief's Effect" (I was a police chief for 10 years.) Those days are now long gone, once in a great while someone will recall my unusual gift and bring me an injured or ill device, and if they ask nicely I will tinker with them, usually with the same effect.
My grandmother had one of these next to her bed. It was in prestine condition. I used to listen to it at night when I couldnt sleep when I stayed at my Grand parents. I think it was 60's anyways. I was actually sad to see it in such poor shape. Hers was not the greatest but it worked. I think they made several types. I wasnt far off on the date. My grandmother always took really great care of her stuff.
I really enjoy getting all the technical specifications and explanations in the diagnosis. Top notch repair done right, not just slapping a bunch of new caps on a board and calling it good.
I love the videos where you change your mined. You are so adamant about not worth fixing, than the next frame you change your mined. Keep the videos coming.
Thank you Shango. I for one, appreciate your resurrection videos. Makes me think about people restoring things after the great apocalypse or something for survival.
A large obstacle to the repair of these radios is a Board made of foil getinax. Thin tracks of copper foil fly off after the first re-soldering. Yesterday repaired a similar radio , now tracks have to be glued with cyanoacrylate. Laughed at the domestic germanium transistor MP 42 (as he there fell ?! heh ) like for video.
I did seen one capacitor that was broken from the solder joint in this video where you started checking other capacitors. All and all, great video! Thank you for sharing!
Several companies made these back in the late 50s and early 60s. A friend of mine had a channel master, that was like this. Pretty decent radio in fairly sensitive, I restored it for her and it was a fun project
As said, tin whiskers I reckon. The heat from the iron has probably cleared them, temporarily of course. Often tapping them will cause the fault to manifest itself. Really really common on the AF11x series seen on a lot of 60's UK sets
I don't know...... That's actually quite an appealing "rat look, steampunk workshop radio"! Without word of a lie, we once had a radio in similar condition (late '70s into early '80s). We never changed the station, never turned it off by switch - Just plugged it in in the morning, and unplugged it in the evening. It ran for years in that condition and never missed a beat. "Old Fido" we called it....
40:22 It may be kereoke but anything beats Shana Easton's screechy voice. Sony went all out with that thing: nice dial, almost-normal-sized AF transformers and a really beefy speaker for such a set. Even with two stations coming in at once, I can tell it sounded pretty good. Those AM/FM clock radios Sony was selling in the mid 1960s, the ones with the "deluxe" walnut case that looked a little home-made didn't sound nearly as good.
So cool. I like bringing almost completely dead looking radios back to life. I also find that newly made alleged transistor substitutes (particularly germanium) do not work as well as the originals. For one Zenith 500 hand wired I had I had to hunt down and buy NOS transistors and hand pick the ones that worked best int he RF/IF stages. Good work!
Vanguard made a very similar radio here in Spain from the 60s all the way through the 70s till they went out of business in 1981.The Vanguard Atlas. They came in different colors, some are AM/FM, AM/SW or AM/FM/SW. 1961 model: www.radiomuseum.org/r/vanguard_atlas_5_pt_s65pts.html?language_id=5 1977 model: www.radiomuseum.org/r/vanguard_super_atlas_fm80ptfm_80_p.html
Great video! In the beginning all that thing picked up was the Mourning Dove channel but you got it to pick up two news stations in two languages at once plus the super cheesy Karaoke network. Pretty neat radio, it actually sounds much better than I thought it would. Sony, ever the innovator!
You're like a modern-day version of an electronic Frankenstein, Shango066, LOL! Bringing dead electronic corpses from the dead. I can almost hear those circuits weakly whispering: "Who disturbs our peace?".
There's a really interesting documentary about the history of the Japanese semiconductor industry, and I remember it mentioning there was an event when transistors in radios started failing en masse sometime in the 1950's. This is probably not the case here but it's still a worthy watch.
I remember you restored a console radio and had LA Oldies disco Saturday night on and played that disco song that seemed to never end. The Google song finder couldn't identify the song even though the song was playing clearly on that vintage radio. However, it was able to identify the song on this radio despite it being all garbly googly.
Now I have only been tinkering with AM raidos since around 1958 when my dad let me begin servicing the old battery pack tube set that we used for our only source of entertainment on our farmstead up in rural North Dakota, where the electrical service failed to come to our place. It has been my experience that when you replace a leaky cap that has failed, you must remove it from the circuit because it places resistance in the circuit, and also allows DC voltage to leak across the leads messing up the balance of the entire set. Just a thought, this could be the problem, or part of it at any rate. Also if you salvage caps from old boards, you should use a leakage detector to see if they leak DC. A cap can check great but still leak DC, and if so can mess with your circuit as well as, in some cases put AC to the entire set and make it a bit dangerous with AC units.
Those old ass germanium transistor's will do exactly what you experienced, they check bad but yet still work, the missing 2.8 vdc came back after you removed the first one, I bet throwing the heat from the iron on it caused it to start conducting again. Great job as always!
Excellent video. This is reality, indeed. 36:00 in and look at all the bad solder joints on that board! And the cracked caps on the top of the board, bad transistors... I am surprised this thing words at all. Geez.
it was when transistor radios where getting popular sony was just getting to sell in this country the plastic must be bakelite its made from plant cellulose so it will degrade best to make a replica new wood or metal cabinet for it that looks like the plastic cabinet the circuit board in it is the same as their pocket transistor radios then so you can put it in a smaller case even a plastic food storage box or a cigar box or box the size of the circuit board all those capacitors definitely change the capacitors they dry out without heat those caps had to dry out faster being in heat, plus change all transistors resistors the heat would degrade the value of them i see the square capacitor needs replacing its cracked the radio is working the parts need to be replaced to increase the receive sensitivity itl be good after changing
This was so much FUN! thanks now for an 'Adult Cocktail'. ; ] Glad to see Organ Donation put on hold for a Swing with Frankenstein, err ~ Two Timin' Jammin'.
I had one of these a while back. Cute radio, didn't work very well. Probably had dried out Japanese electrolytics in it but I never bothered to change them. Nice reverse painted dial though.
I have got away with using pnp 2n2906 in place of AF117 in some applications. Perhaps 2N2904 could work for those, though the bias might need adjusting.
Try 2n5179 or 2n3904 with additional bias for the RF transistors. should clear up sensitivity and interference issues. changing the converter to silicon should make a huge difference
Hey buddy thank you for the video. In your experience what is or are the most sensitive am radios? Is it really the Panasonic rf-2200? I hope you can help,”. Thanks, Joe in CT
I wonder if you could swap the polarity of the Electrolytic Capacitors and the Battery round and then use PNP Germanium Transistors instead?It would just mean your voltages were negative instead of positive wouldn't it?
One of my favorite Shango066 videos. Took me a year to find my own TR-712, in great shape and with the blue/gray cabinet. Can't wait to get it!
The reason we keep coming back is because you gave up 20 minutes in but the videos 50 minutes long you are the man man
Is so nice to see these devices working at least one last time...
My parents had one of those for years in the kitchen.. was always on around supper playing CBC. Recognized it right away from your thumbnail. :D
You brought it back to life ! Now is time to 3D print that case to have a full restoration and be proud of yourself. :)
Shango doesn't do restorations. Leave that to someone else - like on _Phil's Old Radios_ site.
1959, it was a very good year.
Yes, I was 5 !
Great videos.. Watching all of them from Viña del Mar Chil
At 22:00 you more or les gave up on it for obvious reasons. Then I looked at the remaining time on the video and then I knew that you would get it to work again, and you did!! Thank you for the upload!
You really really like saying the word “baked!”
In one video, he mentioned a TV being 'extra crisp'.
You always amaze me! Thanks. Like entering the twilight zone. At first the voltages are bad, later okay! Your reasoning of why the voltages are off by following the flow, you mentioned it at least twice really helps us visualize the operation of the circuit. Keep em coming!

Whack all the transistors with a pencil to break the whiskers loose. That one capacitor had one leg totally unsoldered.
Basically ALL the solder joints looks suspect. I've seen cold solder joints before, but this holds the record!
Not a bad looking radio in its day. Amazed how well those simple circuits could work.
My grandmother had one of these next to her bed. It was in prestine condition. I used to listen to it at night when I couldnt sleep when I stayed at my Grand parents. I think it was 60's anyways.

Thank you Shango, for doing these videos for us. I appreciate all the effort you put into them.
Wow it was beautiful new
About 30 minute mark, is why I respect you so much & am proud to consider myself a student of yours. What a birthday video, thanks man!
Morning Train was originally called 9 to 5 in the UK, but they changed it for the US because of the Dolly Parton hit.
is the uk still upset we kicked out the red coats?
An excellent vid and Sheena Eson sinning in Japanese my day is complete,thank you
"Sheena Eston sinning in Japanese"
A mental picture is forming in my mind... and its _not_ good.
Gilligan keeps breaking it. The Professor keeps fixing it.
DiamondBack662 putting the guts in a coconut sounds like a plan. Sell for big money.
If its baked then try eating it, baked transistors make a great snack.
Perhaps the transistors are whiskered internally, originally shorted but handling them cleared it enough for them to work?
Clean Install, we will be at Knowledge Fest Thank you for the content
Looks like someone with a decent 3D printer, some 3D modeling/design software and too much time could print a new case for it.
Or simply build a wooden cabinet for the internals.
Yes, finally something to watch. Beer, Steak and youtube evening tonight :-D

That’s a radio worth seeking out…especially after it won 🏆 the DX championship in the desert

I was hoping Dragen McSnurglefarrfle would get to talk to some telemarketers.

He's on his way to becomming one of those "never speak" restoration channels that are trending for unknown reasons.

I think we should 3D print a new housing that would be fun that would be fun
Now on Craigslist: Antique radio for sale. Normal wear and tear. This is a RARE collectors item. NO LOWBALLERS. I know what I have.
$79.95
i like sony boomboxes, they have excellent quality and good looking. i have cfs1040s 27 years old and still working
Another fantastic video. Keep 'em coming.
Thanks for the video, it’s making my wait at the airport fly by.
Ok, I just got to the end and not feeling so good anymore.
Every video: "I give up, I can't fix it", then proceeds to fix it.
That's seems to be normal on this channel.
@@robertgaines-tulsa I'm like that too. Drives my boss _nuts_
That's the agony of electronics! 🤣
when you are about to give up, is usually when you find the problem you are looking for
sometimes you have to walk away from something and think about it for a little bit
Used to heat em w s iron those old germanum xistors often recover.
Really enjoy your dry sense of humor working on something as munted as this sorry ancient thing. Fantastic skills-set indeed!
Rat piss will destroy the IF transformers similar to battery acid

I am amazed at the power of Sony, I know they build good shit but this is beyond good, and your skills brought it back to life, sort of, a major win!
