Hi Shango, I'm very glad to see you got it working well in the end. We all break stuff sometimes, I've had my fair share.. That cracked core you found sure was interesting, maybe it was younger me who did that, who knows. I've finally had my first successful transistor radio repair. It was last month on a GE p-746a. All bad capacitors, bad driver, and bad output transistor. Currently working on a 1934 Gilfillan 4-T, going good so far. Power transformer checks ok. Perhaps I should make a video of repairing a radio someday. I'm also getting my first car, it belonged to my Grandfather. It's a 1987 Cherokee Wagoneer. I look forward to getting it on the road after our mechanic gets it running good! Needs a new radiator, fan, tires, etc. Take care and I look forward to more of your videos, Nick

Great video. I am a man from the 50's so I grew up with valvular radios and early transistors. All my old radios still work, crude but still working. Cheers from Patagonia Argentina.
Wow, bring back childhood memories. Fell asleep with a Regency underneath my pillow. Listening to KLVI in SE Texas. I’m 67 now, imagine the am transistor top 40 music in 1960’s. Would love to find another one.
Most things were terrible in terms of build quality back then. Also very expensive, I bet this POS would cost like half a months wage. Repairablility was better because of the simplicity, but parts would be very expensive and hard to get. Today the average person can go to digikey and order a bucket full of high quality, cutting edge parts for like 50$. I hate this "everything was better in the past" narrative when it comes to electronics.
That is made better than radios today, though it is kind of silly to compare them. The typical transistor radio even of the time had tiny speakers. At least this one has a reasonable sized speaker. But I agree there was a variety of quality. You could spend the extra coin and get something made very well or you could buy something cheap. If you lived in the city, did you really need a fancy DXer AM radio?
@@WolfmanDudeA lot of things were done like that then. Collectornet laments over that as well. That’s about the same time that Panasonic and Sony started bringing their products into the USA market and also why they succeeded.
The "interstage" yellow coated transformer with the stylized "L" was made by Lionel the model train maker. The yellow coating is MFP (moisture and fungus proof varnish) applied to electronics sold to the military for use in tropical environments. That radio was made with whatever Jewel could get surplus cheap. Not proud that the front of the case advertises "Made in USA". I would bet that the Lionel transformer cost the US Government more than the entire cost of the Jewel radio at retail! p.s. The case was made out of cardboard laminate with plastic leather coating. Cheap and nasty. 🤢
That chrome faced G.E. is probably one of the best broadcast band radios of all time. They work excellent with the non-powered tuned antennas. Thanks for another great video...
You know it will be a tough one when Shango posts a 1h plus video about an AM radio and uses both the scope and the HP generator in the first half. Great video as always.
That audio transformer looks like a well known war surplus job that had 3 windings at 10,000 ohm CT, 2000 ohm CT, and 600 ohm CT. was popular with hams in phone patch circuits, and also was used in transistorized inverters to get low current B+ voltages for portable tube rigs. It would make a good replacement for transistor audio driver transformers, though a bit on the large size (ok in radios of this era though). That "Lionel logo on the transformer clinches my ID of it. The audio output transformer is attached to the speaker. Those IF transformers are as broad as a barn door. Those cans are too old to have silver mica issues.
Very interesting early transistor set. Looks like they used war surplus parts where they could. I really enjoyed the "in the field" test. Maybe I need to dig out some of my GE stuff and get them going. Thanks for a very interesting video! Ted
Interesting as always! It feels like we're living a flash mob version of Charlton Heston's "Omega Man". Remember that "outside the family there's nothing at all". Great radio produced in the 50's to survive into the apocalypse.
"Whatever Happened To Baby Jane" one of my most favorite Betty Davis - Joan Crawford movies! I remember that scene with the radio, and I guess I didn't notice it was a "Jewel" and I've seen the movie a few times.
When Bette Davis was doing the publicity for "Whatever Happen To Baby Jane?" she would sometimes be asked where was her co-star, Joan Crawford. Gleefully, she would reply "She's dead, and lying on a beach in Santa Monica" to general laughter!
A reminder of the "good old days" when tech like this wasn't so cheap and not built to the most impressive standards. Its easy to see why the Japanese with their tight pricing and focus on improving quality became so dominant for so long
In the daytime, you'd expect a 77 KW station at the bottom end of the band to be copyable 200-300 miles away in a quiet RF area with a reasonably sensitive radio. Over a mostly ocean path it would be longer. In South West England North Spanish stations are just there in the daytime near the coast at the bottom end of the band only.. About 500 miles distance
For a 1956 transistor radio the Jewel TR-1 it works good for what it is, the parts inside looks like parts ment for a AA5 tube radio. GE usually makes good radios, I have that same old great performing GE radio mine is call "Eight Transistor".
Being familiar with the common denominator in the history of RCA and Santa Monica (possibly the beach where the intro clip scene was filmed, if not, the cultural element is appropriate in any case), and comparing all of that in a scattered way in my mind with the defining nature of the respective eras of the late 50’s and today, the rot of the mind and the rot of the flesh seem to conspire in an uncanny convergence, as planned. Call me a conspiracy theorist, but right now that’s just how it seems. And sadly, we are not allowed to hear of the demise from our traditional news-bringer, the news man on the radio. Very much enjoyed the bittersweet video, SHANGO. Your insights into the soul of radio and TV gear never ceases to entertain and enlighten! Thank for being you.
I admire your will to get "hopeless" circuits working, and succeeding! There are many types of ferrite (and iron powder) cores for different frequency ranges. The weak one you tried could be off a coil for an RF frequency stage
Don’t you just love it when you realize that somebody else with a bigger screwdriver was under the hood before you got there to fix what they did? Can you say frustrating boys and girls?
Wow!!! Shango has my GE P-780!!! I didn't find a video on that. I should have known he'd have that piece. It is still my "bare knuckled World Champion BCB radio." *Nothing* touches it.
Absolute gold @shango66 22:39 "maybe it needs some xylazine that would maybe get the selectivity dialled in.." Radio repair coupled with topical commentary. Who could ask for more?
Does anybody remember . KDAY 1580 AM years ago? I can remember getting the bounce at night from Sacramento Ca. on Saturday evening when they used to have there hip hop marathon .
That was a good com-pour-asian between the different radio sets. Luckily you pointed to the sets otherwise who knows how the video would have gone? GE, it brings good things to life.
shango066 Core materials are very rarely identical more dense iron in core slugs for lower frequencies and low iron content for high frequencies, it's something we all catch onto eventually you can test them using and Rf dip meter in a coil to find their resonance not sure you can find a DIP METER ? I have one by MAPLIN mine is model YN48C I wouldn't call your video a dead video anything that learns something new is good 😃
I hit 72 years haunting this big blue marble last May. I have been watching your videos for years now and have been tinkering with transistor radios for awhile now. Last month I hit the jackpot, so to say - every radio I bid on. I won so I had a quick influx of old transistors. I have been sort of disappointed. Nearly every radio had a power problem, either corrosion on the contacts or bad earphone plugs. I had all of them going in around 15 minutes. I did go through and test the caps, replacing a few on each set. Do you have such problem? I love watching you troubleshoot, perhaps I will find some to work on if I keep getting cheap sets. I even picked up a couple mobile tv's for cheap and even bid on and won a broken TI83+ calculator for 5 bucks, opened it up and it was a power problem, the place where the batteries touched a copper plate was spilled on with some coffee (I think) and when I cleaned the pads the calculator works fine as well. Maybe it is just a trend or something.
That big bold "L" on the audio transformer looks a lot like the symbol for Lionel, like in toy trains. It's in an expensive hermetically-sealed can so it might have been military surplus. A lot of companies you wouldn't think of made mil-spec components. THere even was a run of R-390A radios made by HELENA RUBENSTEIN. Weird. Also weird, that three-legged capacitor. Good intuition that the radio was running as a TRF for a while!
I have fixed a broken IF core (3 pieces) with a minute amount of 2 part epoxy years ago. I guess super glue would work as well. The context-- a 6 transistor construction kit and an inexperience hand. That lead me to make a 3 transistor 455kHz alignment oscillator using a new fangled ceramic filter. My wife's uncle told me (back in '72) that adjusting the screws in those little cans gives the radio a better tone! I think these are the first to suffer when a radio was not at peak performance possible due to a dicey battery. .In the late 60s we were taught to always do alignments at lowest possible level to avoid AGC complications. I'm not trying to teach my Grandma to suck eggs, just saying. Best wishes from Australia
I remember there were 5 different cores to those standard coils marked with cyan, red, green, blue and yellow color. Cyan/red were used for FM, green for SW, blue for AM and yellow for AM IF and LW approximately. On FM you can also use core from aluminium, that lowers the inductance.
Şimdiki teknolojinin hiç biri onların verdiği mutluluğu ve hazzı vermiyor. Onlarla parazitli'de olsa radyo dinlemek çok güzeldi. Çocukluğumuz'da içini açıp büyük bir hayranlıkla bakardık😂
I believe the cores have different permeability , I remember reading it somewhere years ago , I think that's what it's called, the amount of iron in the core makes a difference , someone could correct me if I'm wrong, love the transistor radio videos !!!!

reconfigure the diode detector as a transistor detector - was known as the "power detector" . That should make it much better.
