1988 SONY SPORTS WALKMAN Playing Ridiculously QUICK! - Can it be FIXED?
HTML-код
- Опубликовано: 2 авг 2023
- Here we have a 1988 Sony Sports Walkman WM-BF58 sent into the channel by Lee. It has a strange fault where it plays really quick. It does need some circuit board work, but the more I look at things the more I find wrong with it.
Will it be possible to get it playing again? Let's find out.

Back around 1986 my friend lent me his old Sony Walkman. Back then AA batteries were expensive where I come from, so I rigged this contraption with wires to use D batteries, so it all lasts longer. Listened to a lot of ACDC, Iron Maiden, A-Ha, Alphaville, Scorpions, Accept, The Cars, etc. Years later I found out that the Walkman I used was the FIRST Sony model and the first and original Walkman that started it all:). Still miss these simpler times...
I was shouting capstan and pinch roller from the start! They are what control the speed. The take-up spool has to run faster (with slip) to ensure the tape is taken up.
Me too!
Yeah I was it was quite painful to watch him looking for an electrical fault from the start. It was fast because it was just getting pulled by the take up wheel.
Yeah fast playing is the major sign that your pinch roller isn't engaging or wore down.
Every cassette head know that, and watching mate took half hour to discover that was so depressing.😂😂😂
On some cassette players, if you push down the pause button slightly, it disengages the pinch roller but doesn't actually pause, so it's like a fast forward button but you can still hear the tape =)
@@DMadHacks some cassette players with auto search/skip functions also does that.✌️
Some with outputting sound and some without sound.
3000hz is like "Grandma, change the battery in your hearing aids.". Great job Vince
Vince coming out with so many videos I almost can't keep up! This is great!
Brilliant work! Love getting old things back to life like this. HAve not heard The Archers for about 40 years (moved to the US) but it sounds exactly as I remember it!
Kettle has boiled @29:53 =D Great video Vince - that thing was in a sorry state lol
You certainly put more effort into that than I would have done, good job getting it going again. Yes Sony used to use the headphones as the FM antenna.
What I truly enjoy on Vince's videos is the masterclasses he gives on electronics!
Thanks Mate!!
It is fantastic that you are able to take broken and non-functional hardware and to give it a new life instead of just adding to our solid waste problem. Keep up the great job!
Hi Vince, I really appreciate you uploading a new fix video almost every day! Keep up the good work, Greetings ;)
Brilliant Vince you spend so long and go to great lengths to fix things well done it will last a good few years now! 😊
I really enjoy your cassette player videos. Fascinating to see the issues they have as they get older. Also, the Archers went from being alcoholics to helium and cocaine users. Spectacular!
Incredible way to figure out that alignment Vince. Well done!
Love the videos, as always, Vince. I do have to say though, the audio from this one will haunt me for the rest of my days.😂
i came across your videos cuz of my ps5 controller error. (which i couldnt fix haha) incredible content on your channel. clearly presented. enjoyable stuff!
Hi Vince ... Well done again, .. I don't deliberately send hard ones ... :) ...... The resistors I took off were dead shorts, so they were faulty from the corrosion ... Never even crossed my mind it could have been mechanical.
You have a naturally knack Lee 😂 Every item = more grey hairs for me from the stress!
I love it really 👌
@@Mymatevince Grey hairs must be a measure of wisdom and knowledge then!
Well done. It's amazing how much the pinch roller slows things down, I'm surprised the tape itself doesn't snap or stretch. 10 out 10 for perseverence.
why would it snap or stretch? it's under a lot more stress during fast foward and rewind.
Thanks Philip 👍 Gary told me about your repair channel. I will check it out one of the nights 👍
Impressed with your perseverance, especially as you still seem to be suffering with hay fever. Decided against explaining the physics of resistors in baths.
i was shouting with the Computer screen.. "that is no electrical problem" 🤣😂 i was Recognized the problem since i heard the first audio.. 😎
I was at first holding myself from yelling "it's the capstan/pinch roller!".
Then he found 2 resistors missing, and I thought "no, I'm an idiot".
Then he started working on the speed control circuit and I was yelling again.
A roller coaster of emotions
Cheers for ruining the video
Great video, I remember that Walkman coming out new, it looked amazing back then and still does. Glad you saved it 👌👍👍
Great work Vince. Sounds and looks wonderful 👍
Great job Vince always love your videos!
Great fix again Vince.
By the way, for measuring smd parts I have bought measuring tweezers. These are very handy.
Fast playing is the major sign that your pinch roller isn't engaging or wore down.
Every cassette head know that, and watching mate took half hour to discover that was so depressing.😂😂😂
I reckon Techmoan's wow and flutter meter was rocking away when you hit play. My dog wasn't a fan of the tone but fantastic troubleshooting.
Thank You Vince! For me the best Sony walkman is wm-fx 423. I still used this Walkman today. Sony sports Walkman its very rare today's.
I remember when those sport Walkmans were for sale. Never owned one sadly. Great video Vince.
Pinch roller is the first place I would have looked. Thanks for showing the whole scenario.
When I first heard you test this, the first thing I thought is the corrosion had got into the motor or on the adjustment pot.
The deoxit fader is a good product. It was designed not to disolve the carbon tracks on pots. Some variations of deoxcit are more aggressive.
The pickup on it being a mechanical issue is a great thing. If the pinch roller is not putting enough pressure on the tape, that will definitely cause the fault you are experiencing as the takeup real clutch would have no pressure on it, so it would pull through at a higher speed. Sounded like it needed belts to be done given the warbling and porr playback. Great video and I appreciate how you go into the details :)
Brilliant work! Lovely work.. very interesting.. 😊
Stunning. The vast amount of electronic in such a piece of Stone Age, as well as your skills. Something has gone off the rails this time though.. 😂
Interesting. I would have gone mechanical first. Never even thought that the electrical side would effect speed. Used to be able to fast forward whilst playing on some of these and it would sound like yours did initially. All that did was disengage that roller. What I didn't know is you could vary the speed. I had Panasonic ones and they were always half a note too slow. Ie. A B would sound like a B flat when a recording or prerecorded tape was played back. But my Aiwa replacement was slightly too fast. Most wouldn't notice but to my musical ear sounded wrong! But also depended on what you recorded it on first. My pioneer deck was slightly too fast so hence it would sound slightly slow when played back on another device. They should really have put a speed control on the outside linked to that device. Anything mechanical and analogue seems slightly out though and I had to adjust the turntable speed manually when I got one. The flaw in your test is you're assuming the bush records at the right speed. But it should still be close enough to sound fine for speech and only half a note out or so for music. Even one radio stations kit would play quicker than another ones! Noticeable if the same track was playing on both. No such issue with digital stuff now. The Sony has dual headphone ports so 2 people can listen at once. Very sociable.
Cheers Paul👍
quite ironic how a waterproof sports walkman has corrosion. Great vid as usual
The batteries leaked
Love your videos Vince from Canada.
Very nice fix there Vince 👏
The fact it worked wobbly in one direction but didn't turn in the other made me think it's the capstan and pinch roller playing up .
You obviously learnt a lot on this one.
Well done Vince 👍
@Mymatevince Yes, the headphone wires were used as the antenna on all Walkmans back in the day, just thought I'd add that in case someone else hasn't said so already. Nice work, what a pain in the arse that was! LOL Battery corrosion can be a real challenge.
I think the reason why this appealled to so many people back in the day was Sony was the name, it had both a tape player, and also the radio (which didn't have rubbish on!!), and the fact it was more portable than ghetto blasters, only thing that let it down was the cheap speakers that you would get in the shops or car boot sales. now I think it is too niche to be retro, and yet a blast from the passed at the same time, I really liked the design being a kid in the 80's, and not far off being a teen when this was released. the yellow casing was a great colour choice, as it was bright, and vibrant, and would feel like you were someone if you had something like this. great video Vince, and yes brought the memories of my youth back, even though never owned one myself, think the main problem if you were to sell it, is the fact the walkman doesn't have a usb socket, doesn't play mp3, and doesn't have an auto-reverse for not having to turn the tape around. and the fact tapes don't hold as many songs or as higher quality as an mp3 player, so be an extremely niche market for retro items. but great to see one of these 35 years after release. I didn't think they done surface mount components back then either, so an enlightenment as well.
Hey Vince,
I feel like it might be worth stripping the rust from the object using vinegar and then doing some kind of electroplating using nickel in situations like this. Nickel plating would help reduce friction and protect the steel from rusting further. From what I've seen in other RUclips videos, electroplating isn't difficult. Additionally, you can source the supplies pretty easily. I
I suggest you to use your dremel to clean that rusty part it would have been less work for you my friend. I love watching your struggles and the process of elimination to find the faults. Keep them coming.
With these indeed the aerial is from the headphone lead. The longer the headphone lead the better the signal.
This is one where experience helps. Instantly knew the pinch roller wasn't in contact with capstan. I was trying to see it as you played it at first.and couldn't.
Edit, A lot of people had the same thought it seems looking at comments. Crikey, it has some other issues..
I remember having something like this in the early 80’s when I cycled to work. It wasn’t SONY as I know my MIL picked it up for our baby from a boot fair. Ok, I nicked it from him- he was about 2 months old. They were very heavy on battlers- my journey was an hour in and same back- 30 miles. I used Nicads in the end…
Yes they were expensive. I had one. Took it on holiday and was approached by a young lady fascinated. She tried it on while we were in the sea and was amazed it was SORTA waterproof and then commenced opening it open while we were still standing in the sea. I screamed at her "NOOOOOOOO" she said "Whaat its waterproofed isn't it?" My £70 week old Sony walkman was busted. I nearly drowned her
That's just a matter of experience. Next time you know to check the pinch roler first if the tape plays that fast. Great job, as always.
Fair Play! You've done it again Vince 👋
Boy, I feel you with this one, Vince. Watching this video was giving me flashbacks to a broken videodisc player I've been on again, off again working on for years. Each time I think I get something working, I accidentally break something else. Still haven't given up on it though, and each time I go back to it is with more experience than the previous time.
I bought a faulty one of them a year ago. I hope I have more luck😂
Okay it wouldn't be a resistor on that particular Walkman there's an adjustment on the back for the tape speed by the way
Yeah that will supposed to have a spring on it I can see the Springs missing
Yeah they're supposed to be a spring pushing that towards the spinning pin in the middle the rubber wheel is supposed to have a spring you know and I can hide that I obviously think you would have shot a spring go flying if you pull that out like you did so
The entertainment value here was "glad it's you and not me" lol.
Wow not seen one of these since I was a little boy. It was so cool to have one. You was definitely cool if you had one in the 90s
Great Job Vince 👍 Looks like you had a bit of a time with this one! As soon as you said mechanical I thought straight away capstan roller lol. Just a thought you could have always used your scope to measure the frequency instead of an app on your phone 🙂and it would also saved everyone's ears 😂😂😂 Keep up the great work.
I never knew you could Mick, I'll experiment with that. Cheers👍
I still have and use the newer model of the Sports Walkman from the early 90s. Still completely intact and waterproof. Tuning with a self recorded test tape and checking with an app is exactly what i do to correct the speed on my Tape Players.
Wow that played superfast :D Very nice late 80's Walkman in cheery yellow colour. I have neon yellow downhill skiing glasses from late 80's, I guess that was the fashion colour at the time :D
This was a really really stubborn one. So much to do and now it's working great!
Informative and enjoyable video, nice fix but now for the painful part,
The 3k frequency was painful, i suffer from tinnitus and that noise really kicked it off, a tinnitus warning would be nice in future videos please.
Vince, on the resistor, they usually have a tolerance listed.. usually 20%.... Therefore, for the 1.8K a 1.5K would work. Nice job !!!
Gutted still no roller 😂. Great video tho pal and a great repair.
Fantastic fixes.
Magnificent - maybe my favorite of your fixes because the problems seemed insurmountable and yet you worked through them. 99.9% of us out in viewer-land would have just chucked it in the bin ages before 😆
These things are legendary if I remember right, and worth a lot of money on the collector and used market.
I still have my Sony Walkman. Never getting rid of it, as it means something to me. More nostalgia more than anything.
Springs flying everywhere? My kids (3 Girls) were all under 10 in the 80s, and we had shagpile carpet! Oh, the joyful memories of raking through the carpet with a magnet to try and get favourite toys working again after the little darlings had been using them as weapons.
This was my favorite Walkman back in the day. Really liked the locking mechanism because often the door on a Walkman would fail after repeated use causing the head to not line up correctly so that you could hear the tracks on the other side playing faintly in reverse. That lock would hold the tape in well enough to ensure correct alignment, and when all you are getting are everyone's hand-me-downs it made a huge difference.
I won one of these in the early 90s as a kid at the fair doing the baloon pop thing with darts. So nostalgic. I miss my Ren & Stimpy You Eediot album and my recorded bootleg mix tapes from the radio recorder on my Boom Box.
Nice Fix Vince
My big brother has a Sony Walkman. Which is yellow completely different designed than this one right from the early 80s, and it still works perfectly.
Hi Vince, the video is 35 minutes, but how much "real time" did you spend on this? There was soo much wrong with it. Almost painfull to watch. But you did it once again! You managed to get it working again.
I've had to erase the memory from my mind just so I can continue to function. More hours than any sane person would 😂
Good Walkman Vince I like those ones from the 80s
I used to fix Clarion car stereo's so this kind of brought back memories. To adjust the speed, we would have 3KHz test tapes that we would get from Clarion Japan, and we would connect a wow&flutter metre up that would measure the played back frequency and have an analogue metre to show how much fluctuation in speed there is. The amount of variation when you initially played yours made me think the capstan pin roller (think they were called that?) maybe a little bent, as it sounded to vary at a set rate almost to if the pin is bent this could cause speed variations at a rate consistent with where the pin would move as it's rotated. Was surprised it was just the belts.
You'd be surprised how often I end up with the "no resistor big enough" problem xD
Most of my SMD resistor collection is left overs from various custom PCB projects over the years and as I like to make things small for the additional challenge most of the resistors I have in stock or either 0201 or 0402.
So whenever I need one for a repair I almost always end up having to do some silly shenanigans to make it fit on a larger footprint.
I worked on these products on the high tech audio repair line at Doncaster’s Mastercare for Dixon curry’s etc.
g`day vince great video mate ... is that the same type walkman from back to the future movie ??? that marty mcfly had it looks like it??. going from memory
I always wanted the early 80’s Walkman they were fantastic
Well done Vince for sticking with it. Great video as always.
A proper repair this time :) The repair techniqe is correct but next time use dedicated deck to record master tape and 432Hz Sine tone ;) 👍
Vince the bodger, can he fix it?
Vince the bodger, yes he can!
Keep up the good work fella and, as always, stay safe!
Walkman playing fast. Flashback of worn out pinch roller. Maybe Sony did some heavy cost cutting in the early nineties, but even expensive walkmans had plastic bearing. With heavy use they only lasted until warranty run out.
If you were running speed tests a lot, you could go down the Techmoan route using a wow and flutter meter, although your way worked a treat.
Shoulda whipped out the dremel, Vince and wire wheeled away the rust! Work smart, not hard 😅
Oh walkmans were so cool great trying to fix
Reminds me of when i used to play with the high speed dubbing button on an old stereo. Found it hilarious
30:02 kettle is boiled Vince, time for a quick tea break fix😉
I have one similar to this but I think it's older, or newer, not sure and I was able to get it running but the caps are bad in the amp section because I can get audio from before the amp but it's weak after and hardly any volume.
Sometime I will try to replace with electrolytic caps because I have a few of those amazon kits and i believe there is enough room but I don't use tapes for music anymore so there isn't much of a point to fix it and then not use it.
@30:10 I realised i needed to boil my kettle for a cuppa too 🤪
Two parts of mechanism controls the playback speed of tape.
1 is pinch roller (accurate speed)
2 is take-up spindle (faster)
Maybe the pinch roller isn't engaging and the tape running only by the take-up spindle (which is significantly faster to prevent loose tape stucking in the mechanism).
And last but not least demagnetize tape head Vince. Great video👌🏻
i agree with lee though the sony sports range is definitely worth collecting purely on the design
24:53 - Vince summoning a demon through a cursed tape
29:48 Thought I'd left the kettle on! 😁
Hang in there buddy!
Now that the 90's are back in fashion this thing would sell XD
Vince, seeing as you're going through batteries like candy, I would suggest getting yourself some rechargeable ones where and when needed
28:00 Ahh, the wow and flutter test
29:50 Sounds like a boiling kettle 😜
SONY should hire you Vintage-Vince!
At least they should pay you for bringing their old products to life again! 😂👌
Great fix again! 👍
I had the same problem with my Panasonic personal stereo model rx-1925 with the I had to replace a potentiometer with a 1k version. tape speed was slow.
Hi Vince, can you tell me which leaded and unleaded solder do you use and which flux, just starting at soldering. Watch those Amps.
I love your "HI-TECH" type 0 tape. 🤣🤣
Pinch roller not touching the capstan? When I take that I hadn't seen it on the video, have now :) seen that fault before. Could you repair a 70s amp and matching tape deck for me?
One thing to keep in mind is that you don't know for sure that it's playing at an accurate speed, only that it's playing an identical speed to that Bush recorder. You can buy professionally mastered frequency tapes, but they're probably more trouble than it's worth for "simple" fixes.
Those tapes, unless you manage to find an original, are copies made on someone's "calibrated" deck. You have no idea if their deck is good or not.
@@dlarge6502still a million times better than the one from that Bush!
I've heard this before, that we only hear beyond 20 hz, but I can hear a very audible difference between headphones which play 20-20k hz and headphones which play at 10 hz or 5 hz.
Lovley way with 3000hz great work
Nice!
nostalgia at its best
