Im so glad you mentioned the five hours of troubleshooting you did. I don’t feel so bad about my abilities. A seemingly simple device and it fights back hard.
Have a look inside that soldering station, make sure they even put a mains filter in there. I bought a chinesium soldering station and the external power supply didn't have the mains filter populated. Mine also had 100v AC on the soldering tip, great if you need to destroy mosfets.
Wow coffee with Shango! What a way to start the day! That large ITC radio - my eldest sister (RIP) was a bar made back in the 70's at a 3.2 bar in South Dakota (you could drink 3.2 at age 18) She decided it would be cool to sell punch tickets during her time behind the bar. Many of the tickets had radios much like that one but of differing brand names as the prize for the winning punch. The deal with the outfit was, you sell the tickets and send in the money, they send you two of the items, you get to keep one for your payment and give the other to the winning number. She had several of those and I got them from her daughter when she passed away from brain cancer 6 years ago. I fixed them up and gave them back to her 2 daughters as keepsakes of their mom.
I had a really great Aiwa cassette walkman in the 80s. That thing was super tough and durable - mostly metal (and teen tested). It had this crazy fake cassette with a radio circuit inside of it. The "cassette" had a few spring loaded pins that would connect into the walkman circuitry when it was inserted. Then you could switch it on via a control on the walkman and see the tuning pointer through the cassette door. Totally crazy - I wish I still had it. Great video, Shango, including the "tinnitus tone (TM)" sections when you had that cap out of circuit.
I had an mp3 player adapter cassette that would also record. The darn battery compartment lid broke easily. Your fm adapter sounds cool . How was it powered? Friend still has 8 track to cassette to 1/8in stereo male. That was all plugged into a cobra am/fm cb 8 track stereo car radio
@@321CatboxWA I just looked up the model: Aiwa HS-P06 . You can search it for pictures if interested. If I recall, the receiver was pretty decent and the tape mechanism was very well made. I saw some on ebay just now selling for crazy $$. I guess I should have saved mine, but it was pretty destroyed by the time I was done with it. The AM/FM "cassette" had pins for signal and power, so the radio powered up off the walkman batteries when the radio-cassette was put in the player.
Good on you for planting that seedling and giving it a chance. Always knew that you're a good guy. Your head bobing to the Cookie Monster song made me spit my coffee because i laughed so hard. Great video, as always!
Aiwa used to be a decent brand, and at some point, Sony took them over in the 1980's and ran them as a secondary brand for a while. Aiwa made some outstanding cassette decks at one time. Later on they were best known for cheaper stuff like those plastic bookshelf systems that flooded the market in the 1990's.
The late 90s-early 2000s Aiwa mini systems were decent as far as the amp and EQ. The included speakers could be hit n miss, like most mini systems. They cheaped out the speakers and put the $$$ into the electronics. You could always run other speakers with them. Their weak point could be CD player optical pickups- some of those Aiwas used a particularly problematic KSS-something. Of course, belts in the tape decks too- you could fit heavier ones on the pulleys. They used small belts to attempt to reduce wow&flutter; they had to with the low-mass plastic capstan "flywheels."
@@FuturisticNostalgicReturns Yes, even most of their lowest power (like 8W RMS/channel) mini/micro systems use a discrete complementary class AB amplifier with TO-220 output transistors, so they practically never fail, and even if they do from some abuse, you don't have to hunt for obsolete amplifier ICs. Most of their speakers for these systems are OK for their price and size. Some are so cheaply made that they molded the speaker basket and the front of the speaker box as a single plastic piece, and the box is made of super thin particle board, but despite all that, even these are usually sound acceptable for what they are. But the frequency response of their built-in EQ presets and bass boost is often ridiculous, like bass boost amplifying +10dB at 150-200Hz, makes these sound super boomy with no real bass. Fortunately not all of their models are like this.
Remember in the late 1980's purchasing an AIWA 'Dolby C' Walkman, with inner-ear headphones capable of delivering the equivalent of 110 dB. It was expensive, but very impressive performance (auto-reverse, etc.). One disadvantage was the battery life (a small 2V rechargeable lead-acid) or 2 x AAA. I soon learnt to use an external 2 x D cells in a container with gave several hours of operation...
As far as shorted ceramic caps, a shorted MLCC took out a JBL Charge 3 that I got cheap a few years ago. Right across the battery input- the BMS tripped on overcurrent when connected & charge buck converter locked out. Took the board out, found the short. Had to remove several MLCCs to find the bad one. I just left the bad one out as several were in parallel. Kept it for a while, then gave it to a friend.
Nice diagnostic work as always. Interesting shorted disk cap, I've not seen one shorted in a transistor radio before, usually rock solid. Thanks for the effort and usual hard work 👍
Hakko 900 series is my favorite iron so far. Plug irons without a base I haven’t used for 20 years. Was never a weller fan, unfortunately, despite being an American brand. Say what you want about Chinese stuff, but when they do it right, they’re the new Japan as far as quality. That’s why they donate equipment to video makers; they want feedback to make it better. When was the last time weller had a product placement? Or Hakko for that matter? They’re taking over and they’re using the same recipe other brands did years ago. Make what customer wants. Is that simple. Honest and good products win. Every time, long term.
Well they also want to be like the dental products where the brand that donates the most gets to say 9 out of 10 doctors recommend this same vibe dual purpose I suppose Also great word of mouth, plants seeds They look decent enough, I went with a seller though, didn’t realize some of the tips were difficult to get. 😢
That signal tracer, MPCtronics MPC-4, was an electronics lab project at my local college back in the 70's and maybe early 80's. Monterey Peninsula College in Monterey CA. There was also a transistor tester and a few other handy electronics testing related items I can't remember. I think the blank panel on the right side could be removed to fit another piece of test gear into the same box. I think they were all the same blue color. I took a few tech related classes there in the early 90's. Sadly, I doubt there are any hands-on electronics classes there now. So, I come here to learn!
Generic Viagra, 5% cheaper, but your bits might fall off ... Love the transistor radios. I think because I used to try to fix these as a kid and even though I know how they work now, the fascination remains. Thanks for all the work that you do on repairs each week, and all the knowledge that you're sharing with other enthusiasts like myself.
Great trouble shooting job sticking with it. Love it. Great weekend Shango video and first time I have ever known of a disc go shorted never would have suspected it. Thanks for the long days and time. Mike
That Zenith Royal 500 is a good radio. I have a black one that I've owned for nearly 40 years and it's never had any work done to it and still plays great. Yours appears to be in great physical condition
Nice work diagnosing and fixing that beast. As far as the transformers that were out of whack, my late dad used to say that "twitfiddlers" cannot find enough things they can screw around with. Many years ago, I bought a Sony FM tuner from a thrift store that someone had screwed with the transformers and a friend that worked at a local FM NPR station aligned the tuner for me, as I didn't have the proper equipment to align it. Other than fixing the misalignment, the only thing that was wrong with the tuner was fixing a cracked solder joint.
The detector diode is part of the AGC/Bias network that controls the IF stages. So the detector diode might not be shorted, but there could be a problem with an AGC capacitor or even one of the IF stages drawing too much current. Removing the diode could throttle back the IF stage to lower current.
Multilayer ceramic caps often go short circuit, but a single layer one in such a low voltage, non-pulse environment is super rare to do that. I had a blue 1kV one short out and blow up, it was a snubber across the drain and source of the PFC MOSFET in my 2009 Samsung 32" LCD. Weird that they've put just a capacitor across it, without a series resistor. IIRC it's 1nF. Probably the high dv/dt peak currents killed it.
VERY interesting video. These swr radios and new cheaper spectrum displays will be really helpful in my work on old B/C videotape equipment. Somehow I didn't realize it was within reach so THANKS!!!!
Thanks for another transistor radio repair video. I really enjoy the repair process on these tough sets. I really like the solder station. Are you going to take it apart to figure out the power supply noise? Yes to plant cam! Thanks Ted
I looked at the Aiwa AR-132 schematic and it seems to fit,except for some minor differences like for example noticed a 2k resistor in the schematic to be 1.8K in the video. And yes,ceramic discs do sometimes short.The first time I had this was when working on a Sentinel police scanner in the 70's.
Aiwa made very good audio equipment and fell behind around the 90s I think, then Sony acquired it and they still made some very good devices. The brand has died and revived like 3 times already. We have a fancy home system from the 90s and a small boombox. The sound is absolutely amazing.
You mentioned that the fourth leg on the transistors is the can, correct, and they go short internally to the collector, we used to cut the fourth leg and if it was short, the radio would then burst into life
I had a 1980s Cooper-made Weller that lasted for year and years until the heating element failed. I replaced it with a new Weller and it was garbage. I got a Weller clone off of AliExpress and it's been vastly more reliable than the new Weller was and it was 1/4 the price.
An AM radio can drive you nuts...I had my experience with one of those....one timr I connected a long wire antenna straight in the circuit of the tuning...every station came in all at once....😮
Shango, enjoyed the video...had one of those when I was a kid...would you please post the model number of that Aiwa and is there any kind of date or code? I was trying to remember when I got it...thanks!
56:30 put a shorted loop of wire around the ferrite rod antenna to kill the RF signal. Easier than disabling the oscillator which is the other specified procedure.
Sony was the majority shareholder in Aiwa for a few decades - bought them outright in the early 2000's. Sony had them for about five years, was unsuccessful with their plans for the brand, and shut it down. After that a few different companies have owned rights to the Aiwa name.

What’s it called? I’m looking to add hot air to my weller soldering station and none of the big wigs of repair ever say what they’re using for hot air or show it on acreen
Shango, I have a few nonworking transistor radios I've had in a lot on ebay for a while with no takers. I could either post a link to the listing, or I could just send them to you. What would be the best thing to do? Please respond so I can get a notification from RUclips.
The green radios were 5$ from guys walking down the street with one playing and 5 on their shoulder with the carry strap. Fixed a few bad solder joints and crappy wires. Many had a different dial, cardboard case. I see ads on Amazon for solder desolder stations for like 40$ are these things safe to use, I hear they could be hazardous all made in Chy-na
At 26:35 in. That is the worst soldering of a transistor I have ever seen. Shango has a systematic troubleshooting ability to decern the multiple problems here and found the main culprit. Noisy power supply in soldering station whether on or off! Arggh. Aiwa radio model number is AR-117 for those interested.
Soldering iron: Produces RF noise with the front panel PB off. Possibly SMPS creating the noise. Maybe that's why they took the trouble to install a power switch on the back so you can completely kill the thing without having to unplug it?
The like and subscribe comment had me laughing! I get annoyed when every other channel on here does that. I'll like and subscribe if I like the content! The worst is when the pop up of the subscribe icon and bell notification comes up. Makes me not want to like and subscribe, especially when content creators start to nag about it.
Transistor with sheld wire like Af117 suffer from internal shorts due to tin whiskers growing internally as in AF117 if you cut the sheld wire and give it a wack sometimes it clears maybe
Watching something grow is enjoyable. You'll have to keep us posted on the life of the plant.

You're correct, Sony owned half of Aiwa up until 2002 at which point they took over the whole company
Shango Time👍🏻
Very good sounding radio. It sounds great on my Bluetooth speaker. Great repair.
You are very good at what you do. Congratulations!
I'm thinking that the shorted disk capacitor had internal tin whisker disease, if there is such a thing🙂
Great video! I think you should put a switch across the grain of wheat bulb to bypass it when you need to
Don't know much about Aiwa but the signal tracer was made in a Monterey Peninsula College electronics class, I know - I built one.
Great video as always mate. The plant is a cucumber plant I think.
Another expert job!
Excellent video.

I feel ya..I am on the 3rd time this month taking apart the engine in my truck
A bad disc cap. Wow! 3 ohms? It's indeed whopped! This repair needs to go in "Ripley's"
I looked at the Aiwa AR-132 schematic and it seems to fit,except for some minor differences like for example noticed a 2k resistor in the schematic to be 1.8K in the video.
And yes,ceramic discs do sometimes short.The first time I had this was when working on a Sentinel police scanner in the 70's.
I have seen shorted ceramic disks before, but yes it is rare, most likely it got wet at some point or oxidation got into it.
Good job, as always.
Baby plant looks like little cucumber, watermelon or pumpkin.
Sounds like that Radio had a lot of problems, but good job fixing it
Aiwa made very good audio equipment and fell behind around the 90s I think, then Sony acquired it and they still made some very good devices. The brand has died and revived like 3 times already. We have a fancy home system from the 90s and a small boombox. The sound is absolutely amazing.

A transistor radio from the category challenge accepted.1:0 for shango066.
I had a 1980s Cooper-made Weller that lasted for year and years until the heating element failed. I replaced it with a new Weller and it was garbage. I got a Weller clone off of AliExpress and it's been vastly more reliable than the new Weller was and it was 1/4 the price.

It was so funny watching the ammeter move to the record rap jam 🤣
The plant is something in the melon/gourd variety. The leaf shape suggests that, anyway. Diligence pays off for the Aiwa.
Aiwa was the Price Club (Costco) house brand as well.
peace be upon you sir
Nice Soldering Station.

56:30 put a shorted loop of wire around the ferrite rod antenna to kill the RF signal. Easier than disabling the oscillator which is the other specified procedure.
Sony was the majority shareholder in Aiwa for a few decades - bought them outright in the early 2000's. Sony had them for about five years, was unsuccessful with their plans for the brand, and shut it down. After that a few different companies have owned rights to the Aiwa name.
i remeber my dad saying AIWA put the experimental stuff Sony made but didnt want to put on their own high end branding just in case if there are any flaws like the walkman mechanisms and other stuff. I have a old portable tape player from them that has motor bearing failure but still works with a lot of wow and flutter after 10+ years of hard use from the late 90s (things of thos sort will probably never happen on a real walkman) kinda deal.
Those directly heated tip soldering irons are really nice for the price. There are a ton of Chinese ones that use cloned Hakko tips whilst being pretty much the same price as your crappy harbor freight special plug directly into the wall irons. I would recommend checking if the temperature on the display is accurate with a thermocouple or something though, the iron I had was 40c over what was being displayed.
By the end of the next video you're gonna climb that plant and grab a goose from a giant.
Would be interesting to test the actual temperature at the tip of that soldering iron.
My Chinese Special hot air station is pretty useful.
Decapped IC's, worked with SMD stuff (Eg, TSOP48), desoldering, very nice!

Sony bought out aiwa years ago, its their budget division
They tried out new features for SONY maybe? Like Buick for GM. Scion for Yota.
