I have two of these SW7600s (I recapped the second the other day - took around two hours with disassembly, removal, replacement and cleaning). They are fantastic radios and worth the effort of a recap. Currently living in a fairly remote part of Australia and it picks up lots of stuff from all over - sound quality is fantastic too.
I’ve learned that many of the older radios I buy that’re non working is because of something minor which is great for me since I bought them dirt cheap because it wasn’t working. The speaker and a selector switch is usually the culprit and rarely the caps but they get replaced anyway to be safe so I don’t damage the PC boards. Thanks for sharing your work with us!
You are amazing! I first checked the Rubicon capacitors on the radio where I was facing the same issue. And yes, all three are swollen! Thanks a lot! PS: Radio is produced with a very complex electronics. It is very difficult to fault find, thanks Sony. (sorry for my bad english :)
The technology behind surface-mounted capacitors as of the date of manufacture likely hadn't sufficiently evolved to allow for long-term reliability, as these receivers appear to be circa 1988-89.
Hello from a fellow lower mainlander! Have a few Sony’s which I have repaired (new ribbons on the folding models). Had a 2010 purchased with no on/off complaint. Turned out it was the power select switch on the side ‘not being used’ correctly! The 2010 has been tested for low volume, the FET and all other faults and is perfect. It is one of the first runs (low serial number). My question is related to the caps. Mine all ESR perfect and the radio runs to factory spec. And yet it is 80’s. What ages caps a differing rates??? Thanks for the videos and take care, maybe we will get through Mayvember one day! Geoff in White Rock. P.S. just finishing up restoring my Panasonic RF-8000, complete outer and inner; now thats a radio! P.P.S. Do the 2010!!
Hope the owner gives you the go ahead to complete these as it would be nice to see them working! Having said that I don’t know if they’re worth the trouble unless, like you say, you were doing it for yourself!
In this model it basically is not a question of if but *when* the SMD electrolytics fail. A bulk recap and whole board cleaning is commonly required, with occasional board repair work sprinkled in as well if the electrolyte has started gnawing at the traces. Citing the "Quick repair guide" straight off the Sony 7600 series page: "Commonly defective ones include C127 (in the DC/DC converter) and C69, but generally any of them (including those around the audio power amp) may be dead and even leaky. If some are affected, the others usually are not far behind." Just so you know, C127 is inside the shielding can. I may add that the 470µ through-hole Rubycons in mine have aged better than the surface-mount jobs, but are still leaky in the electrical sense, giving rather pronounced rustling in the headphone department. Also, I still have to investigate why the Goldcap that was changed 15 years ago appears to be doing nothing now. If memory serves the ICF-2010 still is an SMD-free zone though. This only started with the AIR-7, ICF-PRO70/80 and ICF-SW1. What I've been told about this old Sony equipment is that soldering process temperatures weren't that well controlled and rather on the hot side to reduce the likelihood of bad joints, and that in turn damaged the rubber seals in the capacitors (which may have been marginal to begin with). It's all a major bummer because this affected some of the best equipment Sony ever made. This particular model is one of my favorite from the whole series, with its good sound, good shortwave sensitivity even on the whip antenna and easily the best AM strong-signal (IMD) handling of the bunch. (Nowadays I couldn't even do this testing as all the "local" MW stations have shut down around here.) I would love to see a SW7600 tested by Sherwood Engineering, so if anyone in the US has one to spare that works...
@@12voltvids Yes but mine failed, two very tiny tantalum bead caps around the product detector went leaky and resistive.They unbalanced the DC circuitry levels around them. If I don't recall wrongly I had to open one of those shielded cans to replace them , not easy.Thinks they were 2.2 uF.
Always wanted one of these small receivers but finally settled with a Grundig Satellite 500. Which sounds very good and is fine for DXing outside. The Grundig is just a bit on the ... heavy side. :D
I just re-discovered my 7600D a few weeks back, was sad to hear the dismal shortwave reception. I knew it had to be the caps... should be a fun job replacing them. Will need some practice on a junk board first.
If it's just the shortwave reception that's stone deaf you may also have a blown preamp FET on your hands. Q7, a 2SK152-2. (Which is not to say that there won't also be bad caps, they weren't exactly premium quality to begin with and the set is now over 35 years old. Having a bunch of Panasonic FCs or similar on hand is not going to hurt.)
@@PileOfEmptyTapes Yeah, FM is fine...but AM including the "regular" AM radio band is quite weak. I will definitely look into the FET... is there any application difference between a -2 and -3? Thanks!
I don't think the caps are open; typically when caps die, they become wires rather than open like resistors. Besides that, at least in modern electronics, you can't reliably measure capacitance in-circuit, because you'll get the sum of all caps in the circuit. Is it possible it could have been just the one or two bad caps throwing off your measurements? Not criticizing, just genuinely interested, I've got a lot less experience in this kind of stuff than you I am sure, just looking to gain some knowledge, besides the fact that stuff like that was made different than stuff today. Thanks in advance if you reply to this.
According to my experience (over 50 years) caps can fail in all manners you can imagine, shorts resistive no capacity, resistive some capacitance , almost perfect insulator and funnily enough some behave as avery low votage (100 mV aprox.) low current battery. Different types of construction tend to increase certain types of failure, but is a general rule not exclusive.
Love Sony radios. The currently made ICF-19 is a perfect hurricane radio: large speaker, very high sensitivity on the AM band with a 4.75 inch very thick ferrite antenna, and runs over 400 hours on a set of batteries. It would be perfect if not for soft muting on AM at night. Totally useless feature!
ICF 2010 puts the rest to shame. It was probably the longest single model in history. It was in production from 1985 to 2003. I can't think of a single other consumer product that was produced for 18 years. It was / is that good.
@@12voltvids Japanese radios were always surprisingly high quality. I`m a huge fan of Sangean too. I had an incredibly great Sangean made shortwave receiver with SSB and programmable cassette recorder I bought in the 1990s and ruined it in 2005 by leaving Duracell batteries in it after a hurricane. I was able to repair it a few times but only temporarily. The circuit board was destroyed. I have a Grundig G6, Tecsun PL-660 & 330, and an Eton Elite Executive now, but that old Sangean was much easier to use and had a real RF gain control knob.
Okay, nevermind. I realized there was a single 22uf 6V surface mount inside the stupid little DC-DC converter that was messing up the voltages to the tuner and that one cap was preventing it from locking onto stations. I replaced it and now seems to work. One thing I didn't fix totally was the plastic clasp for the LCD board is broken, so it's not on there really great. If you have any ideas for getting that plastic collar down there after breaking it I'd be all ears
I need to ask you David - why is your channel then only one that buffers so poorly and slow - I go to other channels and 1080p playback is fine but yours - and yes I'm using chrome ...
Hey - I have a ICF-7600D so similar to the one here on this vid. It does not power up on mains or battery - it sometimes intermittently turns on but does not stay on for long. Any idea on fix pls? (I am not an electrician) but I am sure can solder
Some fail some don't. There was a particular time where pretty much everything that came out of one of the Japanese factories every one of those surface mounted electric caps leaked. The story goes and I've talked about this before, that an engineer was lured away from one company to work for another and he took the formula for the new electrolytic that he had been working on to make these tiny capacitors. The problem was he missed a key ingredient that kept the pH stable on the electrolytic when the capacitor was discharged. This liquid became slightly caustic which then corroded the copper leads going through the seal and eventually leaked out onto the board and attacked the circuit board. Every manufacturer that used capacitors from this factory ran into problems. Sony and Canon were hit very hard for their camcorders in that late 80s to mid-90s cycle. Unfortunately it took several years before this problem was discovered. Devices which were used constantly didn't have this problem because when the capacitor was charged the solution was neutral it was only when it was left sitting discharged that it became a problem and this is why this problem showed up most frequently in devices such as camcorders, because people tended to use them seasonally and then they would sit for months on end unused. Working professionals using their cameras every day they lasted forever they never had a problem with capacitors. My ccdv5000 for example was full of them and I never had any trouble because I used to use it almost every week when I was shooting weddings when it first came out. Once I upgraded to my evw300 professional High eight I set the v5000 aside and just used it as a playback deck because it had a tbc. I hadn't used the camera section for years I just used it for playback and I used to leave it turned on pretty much constantly. One day I went to turn on the camera and found that the camera section didn't work opened it up the entire camera section had leaking capacitors but the VTR section was fine because it was kept powered up all the time. I ended up changing all the caps in that unit about 85 of them and then selling it.
@@12voltvids I do remember that. Well that is quite a story and all us consumers get duped out of thousands in electronics that turn to crap. I wonder if any failed before they were first sold.
That was the story behind the 2000s capacitor issues.

I decided to get out of electronics repair once surface mount technology appeared in home entertainment devices. My eyesight is too bad to repair micro circuits or even mechanical wrist watches They can’t make my eye glasses any stronger
Yup i got out professionally in 2003 and got a job with the phone / internet / cable TV company. Now just a hobby. My eyes were very bad throughout my electronics career. Didn't make enough for laser surgery but once i got on with the phone co, I had enough to drop the 3,300 for Lasik. Never looked back. 20-20 vision. No glasses needed for anything but i use cheaters for real close up work but very mild. Only a +1 over counter cheaters. It's amazing what they can do now. Here i am almost 60 and everything still works like it did when I was 20.
But is Sangean that copied them many years later, and still Sony is better. Sony's co-founder Akio Morita was a SWL and personally tested them until he died then things changed.
The original ICF7600D dating from 1983 fortunately didn't have surface mount electrolytics, it has very large rectangular number buttons, mine still works great after control cleaning etc. Possibly the change to surface mount electrolytics came in 1987 with the 7600DS,same case, slightly different colour.. Think the model in the video started production in 1989.
I have an ICF7600D. Looks a bit different than this model. It’s suffering from fuzzy FM audio. Looking forward to your upcoming repair videos. Pretty sure it also needs those caps replaced.
The 7600D still is all through-hole affair (very tightly packed I may add), but small consumer-grade electrolytics don't last forever either. Those in tuning voltage generation would be most suspect. If you replace every cap that measures out of spec ESR wise with some Panasonics FCs or similar you should be good for decades to come.
Friend, I have a radio like this Sony ICF 6500W and it started to run the frequency and it doesn't stop. Have you ever had or know people who have had this problem and how to solve it. I thank everyone.
Probably a bunch of leaking caps and a destroyed circuit board. Good luck. I washed my hands on these before I got too deep. There is a reason I walk away from "dogs" as they are known in the service circles. Yes you can fix anything by repairing traces and pouring plenty of parts and money in. The problem is when you charge someone a pile of cash to fix one of these they expect that it is going to last a long time and there is no way to guarantee this. With the quality of new parts it's hard to guarantee even the new parts. There has been more than a few instances over the past 40 years I have been in the business that i let a customer's emotions get the better of me (usually involving am attractive woman with something special to her that is broken) and it has come back to bite me in the ass because a few months later something else breaks and then more time is wasted and this time they don't want to pay. A few months later something else breaks. End up getting married to a repair and then all the money i thought i was making is gone and I am in the red and miserable. So from experience I avoid devices that from experience are going to be problematic. Old video cameras and walkmans fall into this catagory. All three devices when designed had an expected life of 10 years. Beyond that you are on borrowed time. Even for lightly used devices it's time not usage that affects them. Seldom used devices tend to be far more problematic that. Well used devices.
Hi..I have a 7600 d..its frequency is a bit wrong..for example 153 khz radio romania is at 156 khz..3 khz above..how can I fix it? Can I make it myself or a complex repair for me? Thanks for your help..I am a maths teacher from izmir Turkey😊
@@12voltvidsYes, the clock display just flashes and sometimes the battery empty icon appears in the display and can't turn on the radio. This is the case with fresh batteries and even with AC adapter plugged in.
I recapped mine and it worked perfectly. Suddenly (after a few hours) it lost all sound even tho it I can see it locks well on channels. I replaced the amplifier IC and still to no avail. Any idea what could be causing the problem? Sometimes the sound returns on it's own, very low and intermittent. Also in a headphone, one side only.
@hippohoppa i pretty much refuse any small devices with leaking smd caps. I might work on sonething of my own but I walk away from most customer gear with leaking caps for that reason. You recap a board and have it working and 3 weeks later it is back with a different fault that stems from corrosive electrolytic that has soaked into the board and corroded internal layers on multi layer boards. Then because money was charged you have a pissed off customer that wants it fixed for free or a refund. It's a no win situation so I cut my losses and just flat refuse the work. I don't need aggravation at this point in my life. I don't need to prove anything to myself or anyone else. As the great quote from lethal weapon went.... "I don't give a f**k"
@@12voltvids Very understandable. These caps were a menace to be honest. Ruining a good product like that! And you have every right to feel so. Totally wouldn't be your fault but a customer wouldn't get it. I have tried fixing these on my own so I get it. The amount of hard work put in it and all for nothing? You are right all the way. Thank you very much for the video and your replies..
I just noticed your vintage Casio watch. Very cool. I had one of those many moons ago before I stopped wearing a wristwatch. Now I just use my cellphone.
Not me. That means dragging my phone out to check the time. I check my phone only a few times a day. I don't respond to text or messages when they arrive. Sometimes it fakes me hours to respond.

If it was mine yes but the owner didn't want to spend money because I would have charged more than he could have doks it for.
@@12voltvids totally understand. Great video, as usual btw.
I’ve learned that many of the older radios I buy that’re non working is because of something minor which is great for me since I bought them dirt cheap because it wasn’t working.

There has been more than a few instances over the past 40 years I have been in the business that i let a customer's emotions get the better of me (usually involving am attractive woman with something special to her that is broken) and it has come back to bite me in the ass because a few months later something else breaks and then more time is wasted and this time they don't want to pay. A few months later something else breaks. End up getting married to a repair and then all the money i thought i was making is gone and I am in the red and miserable.
So from experience I avoid devices that from experience are going to be problematic. Old video cameras and walkmans fall into this catagory. All three devices when designed had an expected life of 10 years. Beyond that you are on borrowed time. Even for lightly used devices it's time not usage that affects them. Seldom used devices tend to be far more problematic that. Well used devices.
Excellent
Hi..I have a 7600 d..its frequency is a bit wrong..for example 153 khz radio romania is at 156 khz..3 khz above..how can I fix it? Can I make it myself or a complex repair for me? Thanks for your help..I am a maths teacher from izmir Turkey😊
My 7600GR doesn't turn on. The display just flashes ' 0:00' .
The power switch is Ok' 🤔
That's the clock that glasses 0:00 as it is in 24 hour mode. That's 12am. Those radios had leaky caps all over the place.
@@12voltvidsYes, the clock display just flashes and sometimes the battery empty icon appears in the display and can't turn on the radio. This is the case with fresh batteries and even with AC adapter plugged in.
I recapped mine and it worked perfectly. Suddenly (after a few hours) it lost all sound even tho it I can see it locks well on channels. I replaced the amplifier IC and still to no avail. Any idea what could be causing the problem?
Sometimes the sound returns on it's own, very low and intermittent. Also in a headphone, one side only.
Probably Christian on board from leaking caps.
@@12voltvids Oh I see.. probably that. it was put aside for 20 years without usage 😢
@hippohoppa i pretty much refuse any small devices with leaking smd caps. I might work on sonething of my own but I walk away from most customer gear with leaking caps for that reason. You recap a board and have it working and 3 weeks later it is back with a different fault that stems from corrosive electrolytic that has soaked into the board and corroded internal layers on multi layer boards. Then because money was charged you have a pissed off customer that wants it fixed for free or a refund. It's a no win situation so I cut my losses and just flat refuse the work. I don't need aggravation at this point in my life. I don't need to prove anything to myself or anyone else. As the great quote from lethal weapon went.... "I don't give a f**k"
@@12voltvids Very understandable. These caps were a menace to be honest. Ruining a good product like that!
And you have every right to feel so. Totally wouldn't be your fault but a customer wouldn't get it. I have tried fixing these on my own so I get it. The amount of hard work put in it and all for nothing? You are right all the way. Thank you very much for the video and your replies..
You Done it but only FM working. MW and SW also not working? Please fix it properly. FM MW and SW all bands work perfectly.
Owner won't approve estimate to repair, so that is as far as this one goes. If it is abandoned i will revisit it.
@@12voltvids ok thanks for reply Sir
I love those sony digital radios
I just noticed your vintage Casio watch. Very cool. I had one of those many moons ago before I stopped wearing a wristwatch. Now I just use my cellphone.
Not me. That means dragging my phone out to check the time. I check my phone only a few times a day. I don't respond to text or messages when they arrive. Sometimes it fakes me hours to respond.
Dave, get some quality caps for your sony, no fango chango crap.
It's worth it.
This is not my Sony and I gave the owner an estimate of 75 to recap and he said not worth it, so they won't be fixed.
Sometimes known brand caps fail before dubious ones, there is an element of unknown with caps.
