Sony TR712 AM Table Radio Resurrection TR 712

[@crooner2007]

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!

[@drgusman]

Is so nice to see these devices working at least one last time...

[@ladamurni]

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!

[@khx73]

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

[@LyonsArcade]

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

[@mrpedrodrodriguezsr7628]

You brought it back to life ! Now is time to 3D print that case to have a full restoration and be proud of yourself. :)

[@RoughJustice2k18]

Shango doesn't do restorations. Leave that to someone else - like on _Phil's Old Radios_ site.

[@jwl9286]

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!

Perhaps the transistors are whiskered internally, originally shorted but handling them cleared it enough for them to work?

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!

[@TheGuitologist]

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.

[@scottfirman]

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.

[@pcno2832]

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.

[@JerryEricsson]

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.

[@michaelrobertson575]

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?

[@cambo1200]

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.

[@gabevee3]

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!

[@teacfan1080]

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.

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

[@doctorwacky5680]

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

[@TheEPROM9]

Wonder if they have a tin whisker issue

[@Elfnetdesigns]

germanium are crystals, they do grow and short out. He opened the short when he desoldered them.. The extreme heat is sometime good for things like that

[@IrishvintageTVRadio]

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.

[@Membrane556]

I read that happens and they can some times be treated to blow out the whiskers. www.markhennessy.co.uk/articles/vintage_transistors.htm

[@Elfnetdesigns]

heat from desoldering will temporarly open the internal shorts "Blow out" but it does not last. They need to be replaced with original parts or silicon with some conversion or the whole unit scrapped. The radios in it's physical condition is not worth full restoration and would be best used for parts to bring another radio back to life..

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.

[@JerryEricsson]

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.

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.

[@jordandoe2768]

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!

[@RoughJustice2k18]

Kim Kardashian has more than enough plastic for several radios.

[@ka2rwp]

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

[@LAVROEA]

Откуда автор советский транзистор взял ?

[@GrandsonofKong]

So most of this older transistor stuff up thru the mid-60's or so has germanium transistors, which could be expensive or even un-obtainable. Especially if the application is higher power like an audio amp. So is it practical to consider re-biasing the given circuit sections for Silicon Transistors over Germanium to return it to functionality? From what I've read is that if the battery voltage is too low it may not work given the higher base-emitter voltage of 0.2V to 0.6V of Silicon. Just looking of an opinion.
