I wish ALL walkmen were that easygoing and relaxed to repair when it comes to the belts. Everything here was soooo easy accessible. While in so many other models you have to dig deeep down into the components and pretty much completely tear the whole thing apart only to remove and replace the belt (or belts). You were really lucky with this one, Maddi.
Yes! This one was surprisingly easy when it came to belts, I coudlnt believe how simple it was, if it wasn't for that tyre getting grease on it this would probably be a more simpler repair and restoration.
I recently bought a Kt-s1 with the exact same murder nightmare scene inside, just black goop left of the old belt. It’s working perfectly now and your video was super helpful! Thanks!
I had one of these last year and I can say that it was my best walkman. I've had numerous walkmans since then but none have come close to how good this one was, i had absolutely no problems with it at all. I really regret selling it last June. You don't know what you've got till it's gone!! Love the vid!
Great job. I had one of these in 1981 and never forgot it. I just bought one on ebay, and then found your video. One of the most amazing devices I have ever owned. Portable cassette players never got better than this in my opinion. Congrats on finding this in such good condition.
Thanks for the video. After watching it, I was able to fix my KT-S1 and KT-S3. I have a KT-S2 coming and I'm optimistic that I'll be able to fix that too!
Those tiny screws... happens to me all the time. It's like they sometimes just fall into a black hole. I had the same "black plague" sticky belt thing happen to me this week, as I just finished repairing a hand-me-down 18 year old Aiwa all in one system (which also gave me several few "why am I doing this?" moments). Everything was worn and extremely crusty inside from sitting in a hot kitcken (no a/c) for several years plugged in just to hear FM radio. CD tray wouldn't open/close, volume knob wouldn't respond, disc wouldn't spin, tape heads were all covered in green crud, bad belts of course, and apparently just the right environment for small reptiles. I was shocked to discover a large gecko fossil wedged right up against the power supply circuit board. Amazing what you may find inside sometimes. It's all restored and working now, though I think it needs new heads (it still sounds ok... you think DeOxit may work to free the corrosion?) . By the way, I found that using a tape with white noise works better than just a sine/square wave, because you can more easily find that sweet spot when you make it sound the brightest. The Aiwa has a "karaoke" feature which works by cancelling out the center channel. This actually helped alot to adjust the azumith, because you know when you found the right spot when it goes silent due to phase cancellation. Oh, and a couple ideas on how to adjust the pitch: one is to use a phone app like a guitar tuner that can detect and display the pitch in Hz for comparison to your Sony player, and the other is to have a second copy of the azumith tape running simultaneously on both players and trying to get them to phase together.
I think i'm going to use a magnet next time with those tiny screws, I should have done that this time but it just didnt occur to me. yikes, I think your Aiwa must have been a serious victim of nasty kitchen grease as well as all that steam and moisture. I don't blame you for having that "why am I doing this" moment, I wouldnt like to work on that lol. You could give Dioxit a go and see what happens though on the head.. i'm not sure, it's supposed to protect, there fore it must leave some film or something... i'm not sure how that would be tape head friendly or not. I may try white noise actually... it will also leave less ringing in ears! Thanks for the suggestion!
I love the enthusiasm! Watching this I thought, "You need to search eBay for 'tweezers electronic set metal anti-static' ". I have a set - they're fantastic. Oh, and an ice-cube tray is a great screw holder!
I need some help. I am obsessed with my collection of Toshiba cassette players. Just acquired a KT-R1. Had a broken wire in battery compartment. The belt was disintegrating. Replaced it. My problem now is radio works great. It FF AND RW perfect. The cassette player has no sound. It works, but no sound. I noticed that the record light stays on. What can I do? It's like brand new.
We got a great example right there of how belts perish over time, with the sticky bits on your table XD "Darkness, go away! I don't need you. This is a place of Light!" That was awesome, haha. I'm dying, Lovely video as laways :3 DeOxit I call "miracle in a can", it's truly a terrific product
Oh you have no idea what a mess i have found in my Aiwa TPR-300A radiorecorder. The gooey... goo these belts have turned into is worse than liquid tar >_< It's really really nasty...
I had one of these, it never failed even after several high speed falls on the road when my friend and my brother dropped it when riding their motorcycles. The headphones were fantastic. Very high output, clean sound. It was stolen after about 5 years of use, or I would probably still own it today.
I have that kind of walkman many many years ago it was thrown by our neighbors. i repaired it. but unfortunately it broke altogether. so i threw it after using it for a year.
Today I bought Crown SZ31 "new" (unused) full package and works as well as I remember. It was my preferred walkman in my childhood. I still have that old one but does not perform properly.
The rubber has srunk over the years and the rubber around that wheel originally had a rough surface kinda like sandpaper. Once the Rough rubber surface is gone combined with the shrinkage causes a gape between the drive wheel and that's why there's no fast forward process.
I could listen to you all day. This pandemic is making me creative again. If you still exist would I be able to send my Toshiba cassette players to you for repair? Thanks for making life a little easier. From the Old Man and the Sea Scooby Doug
wow! genius at work..so awesome to see you made it work..also first time I see a demagnetizing tape and the one with the tones..I learned something new..thank you!
Nice, I'm ordering one of these soon that will no doubt need to be repaired, and I KNOW this video is going to help me out a great deal. Thanks so much, your passion and excitement is infectious.
I synced a tape deck up with music on my PC, then used it to record a tape of a 440hz tone. Now I just adjust the speed by measuring it with a tuner app on my phone to make sure I'm at the right pitch (datuner is a good one)
You do a very good job from start to the end. Your are very professional and competent. I wish I were 1/2 of that. I've learned a lot from your videos. Thanks and Congrats!!!
You are excellent. I have huge sound systems devices like Walkmans, amplifiers, soundbox, vintage radios etc.....Engr. Moksed Ali from Bangladesh. Thanks
I like the aesthetics of the Toshiba, any portable stereo with a big tape window, but I'm always hesitant about buying one because they don't feature the Dolby NR chip. Oh, and a tip when working with anything with lots of screws use an ice cube tray.
I think you are right, the Deoxit overspray "lubed" the tire causing it to slip. You could save yourself some hassle by using a magnetic screw driver for those tiny screws then demag the head after :D. My KT-S1 probably needs a better belt, I just used what I had that was new but probably too thick a belt and so it plays a bit wobbly. Cheers and thanks for the vids, your laugh is infectious!
The screw driver was a little magnetic, but yes I should have got a magnet to stick those screws to so they wouldnt roll over the place lol, I think I will do that next time ;o) ... And it my pleasure, Thanks! :o)
After applying any lubricating or any cleaning solution you could place the whole thing in bright sunlight for 10 minutes to dry. This will help I think.
I work on watches but am nervous about working on my Walkman collection or my Sanyo 9998k which needs new belts, I think it is due to the fragility and mix of electronics and mechanicals. Keep up the great videos. 👏
I just bought KT-VS1, It has same issue. Can you recommend me from where i can buy replacement belt I want this size. Folded Length: 137mm/5.4in Width: 1mm/0.039in
I'm probably the last one to figure it out, but another way to adjust speed, and this would be a non technical way. Get one of those cheap guitar tuners. Record a 440hz tone (same as a A musical note) froma known good deck and play it back in the walkman and use the guitar tuner to measure it to a accurate "A" note. Saw this in some other you tube video and seems like a good idea. Espicially when you dont have all the testers and oscilloscopes of a shop.
Did you figure out the radio part. ? You need the FM cartridge that goes in it like a cassette tape. The hole in the cover is for the tuning wheel. I still have one of these but haven't used it for some time now.
Ah, a perished belt - reminds me of my repair of my Amstrad CPC 3 inch floppy drive. Cleaning up the rollers was really tedious, can't recommend it. :-D
MsMad Lemon: Excellent videos! How about showing us a restoration of the AIWA HS-T06 Mk2? Mine needs a new belt and a proper cleaning. Also has a crackly volume control.. Mech is the TN52 Aiwa setup- like the G35 has. Please...
I have the KT-S1, replaced the belt that had turned to gunge, and it works, but has one annoying problem. It will randomly just power off until tapped on the top. I have been inside and looked at the top of the main board, and have isolated the apparent fault to just inside a square hole about an inch below the radio/tape switch. Inside that hole is some kind of switch I think, and inserting a small screw driver and wiggling gets the power back on again. But I cant get it to stay on for long, seems like some moveable plastic switch down inside? How do I get to this as its inside the main board and cant really see how to lift up the circuit board to see whats going on. What is this switch inside the square hole?
Have you repaired damaged tapes? I have some that I have to split the original case because the tape either makes noise or they do not turn. And install the tape on a case that has the screws so you can open those. I wish there was a way to open original tapes without destroying them.
I have done a few times yes, if they do not turn or feel too tight, hold the cassette from one end and tap it on the palm of your other hand a few times, it somehow loosens it. Yes i'm not a fan of tapes which don't have screws, there's just no way without destroying them.
I will try your suggestion, hopefully it will work.I found a tape box set of a live concert of Bruce Springsteen wich comes with 4 cassettes and they are all stuck. :-(Thank you for the tip.Saludos
You can get fairly cheap 3000hz test tone cassette tapes that have been recorded from direct drive decks on Ebay. Then its just a matter of using a multimeter with Hz setting or a pc with line in to make the speed right. Its alot better than just using your ears alone... However be warned that if you are a perfectionist and you get measurements that precise its easy to become Craaaaaazy with how inaccurate your tape decks really are.. I should know.. Ive been there :D
I tend to be a perfectionist when it comes to head alignment but with regards to speed, i'm resisting falling into that trap which you know well haha. As long as the speed is close enough, i'm satisfied :o))
Oh and by the way, you should save that 5 minutes of Tuning sound as a flac file so you can always play it as a steady running reference when you have the cassette in the cassette deck who's motor speed you are tuning to. So you can do it in one step without swapping the same tape between two decks ;)
Thanks so much for the tutorial. Thanks to you I was able to repair my Toshiba kt-s2! You're a life saver! But what was that demagnitizer tape thing you used? What is that for? And is it mandatory? I don't have one...
It's my pleasure, i'm glad you managed to get your Toshiba working! Over time, the tape head gets magnetized, and requires demagnetizing to restore it, I wouldnt say it's urgent, but if you have a good demagnetizer, it's worth doing it.
Hi, im from Uruguay. 2 days ago i buy one. I oponed and change the belt and is working beatiful but there's something with the volume. It sounds to low. Any idea why? Sorry for my english. Cheers.
Very cool video! Would you believe I have the exact same one with the exact same problems when I got it! The rubber wheel on the forward takeup reel is quite finicky on mine when it is in play mode. These actually have an auto stop mechanism (only for play) that works off of the forward takeup reel, but it depends on the outer part of the wheel rotating as the inner part slips to unlatch the play button. Did you ever see if the rubber wheel is strong enough to engage this auto stop mechanism on yours?
I've recently got one of these and unlike my cassette deck forward and rewind don't stop automatically when it gets to the end of the tape and have to do it manually. It does stop automatically when playing and reaches the end but not forwarding or rewinding. Is this normal?
The best thing i've found is 'Dioxit Fader' it's a bit expensive but the can lasts you and it does a good job, I wouldnt use any other dioxit variant though, just the one specifically for faders.
I highly recommend getting a pack of these: www.ebay.co.uk/itm/35x-Universal-Mix-Cassette-Tape-Machine-Square-Belt-Assorted-Common-Belt-DIY/162493080522?hash=item25d557a3ca:g:pjoAAOSwrhBZAbFp
I just got this machine from eBay. I think it was sitting in the box since the 80s and was in really good condition. I just had to adjust the tape speed thing because it was playing too slow and the belt was fine. My only problem is the volume seems to be super quiet. I read somewhere that maybe I need to replace the audio capacitors. Is this a hard thing to do? Thanks for the video :)
Thanks, and congrats! :o) .. I wouldnt say replacing the audio caps is a hard thing, just as long as you find the right replacements however I must tell you that mine is quiet also, sometimes i'm listening to it while it's full volume and it just sounds normal lol
MsMadLemon oh well if yours is quiet too maybe that's just how these were made. I can crank up the volume on my speakers at home and it sounds great but listening with headphones seems very low at Max volume.
@@Amasloth Hi ... it's pretty loud. Replacing caps helps. Mine had just the buzzing sound with no volume control effect on this buzzing sound whatsoever. I replaced all the caps. Sounds quite good now. Though I'm struggling with slow speed and take-up spindle/pulley/spool. I have tried IPA so many times on the rubber tyre....works very weak for sometime then gives up. And play speed is about 80Hz slower for a 440Hz tone.
Hi! Thank you for your video, great stuff on your channel! Thanks to you I managed to change the belt on this walkman, the old belt was melted and then horribly solidified on the tiny motor wheel. Anyway, the walkman works but not properly as a I noticed a couple of issues: 1. it plays slowly. when I adjust the motor speed to maximum it is not fast enough and sometimes it's not able to hold that speed. 2. FF and REW don't work smoothly, sometimes I have to press play, then stop and then FF or REW in order for them to work, it looks like they struggle to start spinning (could it just be because of poor batteries?). These problems seem to affect the way the tape re-wraps inside the cassette case (sorry I don't know how to describe it better). What are your thoughts about it? any advice? Many Thanks :)
I had the exact same problem with my Walkman WM-F1, it is probably the tape speed adjustment, mine was a bit corroded, I used some isypropal alcohol and some contact cleaner and twisted it back and forth and presto it fixed the speed back up! Hope this helps man!!! 🎉
Excuse me Maddi, But I need to ask you a question that will help me on repairing my Toshiba KT-S1 😅 It seems to be in need of some lubrication and whatnot and I'm curious to know what kind of lubricant I should use or which you would recommend me 😊 Also, would lubricating it possibly help with it's wow and flutter or is that a whole different thing? I would gratefully appreciate if you could help me Ms. Maddi! Thank you very much and I love your fantastic videos!
Luis, I would be very careful lubricating this, as you can see in the video i tried and it ended up greasing the part i didnt want and i had to drench it in IPA to get the lubrication off... only on the mechanism and only a single drop of even singer oil would do... Wow and flutter is different that can be caused by bad belts or a bad pinch roller, And thank you for the kind words :o)
I have a beloved Rio Karma 20gb MP3 player which only plays in mono. I can get it to play in stereo if I angle the jackplug with a little pressure, but it is a custom socket which the mini-jack sits inside, so I don't think it's possible to replace it. Is there some sort of soldering trick on the internal contacts I can try? Any ideas?
This is a faulty stereo one? i'd try cleaning out the socket first thing with this dioxit stuff or isopropyl alcohol just in case the contacts need cleaning. if i'm understanding right, it seems like contacts have been bent out of position?
Great suggestions. I'll take a look. Make sure I'm extra careful. It's made out of quite cheap plastic unfortunately, so the screw holes are ultra fragile now. I'd love one day to make a new case for it somehow, as the software/firmware is beyond awesome, even today.
I put 1.2 V batteries in this but it didn't work. I noticed it required 1.5 V batteries so is this the problem? The reason I'm hesitant is because I put 1.2 V batteries in an Aiwa that required 1.5V batteries and it worked fine
1.2v AA batteries will work (rechargable AA batteries are 1.2v and not 1.5v) and I use rechargable all the time anyway, try this with new batteries to test.
Of course you did ;o) .. but it's about the journey not the result lol Though not everyone did, only those I noticed who really liked this walkman :o))
interesting :-)) another question about the alcohol. why is everybody using isopropyl? it is so much easier for me to find ethanol... is there some advantage using isopropyl?
That is a good question, one thing I know about Isopropyl alcohol is that apparently it doesnt have any greasy contaminants, and tends to thin out grease, if there is any moisture, isopropyl or IPA tends to evaporate it quicker as far as Ive read before... i'm not sure on the properties of ethanol, how it is in comparison to IPA.
And another thing I know is that ethanol I think dries out skin more than IPA, which is why IPA is also known as 'rubbing alcohol', used for skin/wounds etc...thats the limit of my knowledge about them both :o)) lol
Hi Maddi, Great video as ALWAYS!. A couple of comments, not criicism, just trying to pass on my knowledge. Caig DeOxit is really great stuff, but for faders like the one in the Toshiba, you should use their Fader product. Faders like the one in the Toshiba have a grease that allows the large slider to move across the surface freely. Regular DeOxit tends to wash away the grease and as a result the fader tends to stick in certain spots and not move smoothly. www.mcmelectronics.com/product/200-204 This product will replace the grease that has been removed. www.mcmelectronics.com/product/200-206 Second, there is a great product called Rubber Re-Grip that is a chemical conditioner for rubber and is great for the idler pulleys and rubber surfaces. It makes them almost as good as new and gives them a new lease on life. It is especially handy for parts that require much disassembly to replace the rubber. Here is a link: www.mcmelectronics.com/product/20-230 Third, look into a screwdriver magnetizer/demagnetizer. It is really helpful in working with tiny screws. And working on a towel keeps the wayward screws contained and stops them from bouncing off into oblivion. www.mcmelectronics.com/product/22-25525 And last, you should look into a FFT program for your computer. It turns your sound card into an audio spectrum analyzer and would allow you to read out the frequency of your tape to set the playback speed. Do a google search for FFT software and you will find many available. -bob
Nice! i'll look into the rubber conditioner first thing! I'm going to use a magnet next timefor the tiny screws, at least to stop them going all over the place. Thanks Bob! That is a lot of very useful info,
The Re-Grip isn't perfect. It works best on glazed and hardened surfaces. If the rubber has turned back into petroleum, it won't help at all. Before trying to replace the rubber, the Re-Grip treatment is my first step. I am not sure what the actual chemical make-up is but it is very strong. I recommend using it in a well ventilated place.
You are giving me so much confidence in fixing my own KT-S1. You’ve made this process seem so much less intimidating, thank you!!

Sounds great.. what a great job. Thanks :)
Did you figure out the radio part. ? You need the FM cartridge that goes in it like a cassette tape. The hole in the cover is for the tuning wheel. I still have one of these but haven't used it for some time now.
Oh dear, so it works like a car-radio cassette adapter? I've never seen something like this but that's super cool :D
Here is a link of what it looks like. picclick.com/Toshiba-KT-S1-Vintage-Walkman-FM-Cassette-Player-222461352722.html#&gid=1&pid=6
Sweeet :D I like the symbol on the dial that seem to resemble a tuning fork.

Really great video. I'm learning a lot from your videos. Brilliant.
Thank you!
Thank you for posting these videos!
Ah, a perished belt - reminds me of my repair of my Amstrad CPC 3 inch floppy drive. Cleaning up the rollers was really tedious, can't recommend it. :-D
Looks like one of the those cheap magnetic parts trays or dishes on Amazon would come in handy for those tiny screws.
That would be ideal actually! I was thinking about using a piece of magnet next time.
How cool is that cassette player box?! Had me fooled
MsMad Lemon: Excellent videos! How about showing us a restoration of the AIWA HS-T06 Mk2? Mine needs a new belt and a proper cleaning. Also has a crackly volume control.. Mech is the TN52 Aiwa setup- like the G35 has. Please...
I have the KT-S1, replaced the belt that had turned to gunge, and it works, but has one annoying problem. It will randomly just power off until tapped on the top. I have been inside and looked at the top of the main board, and have isolated the apparent fault to just inside a square hole about an inch below the radio/tape switch. Inside that hole is some kind of switch I think, and inserting a small screw driver and wiggling gets the power back on again. But I cant get it to stay on for long, seems like some moveable plastic switch down inside? How do I get to this as its inside the main board and cant really see how to lift up the circuit board to see whats going on. What is this switch inside the square hole?
thank you for making this video!
Are they any significant change after using those demagnetize Cassette? i was thinking getting one, love the azimuth green color cassette
Nice! I was wondering if you'd apply some crud from the first belt to the second to get it to engage :D
Silly me, never thought of that! ;o)
Have you repaired damaged tapes? I have some that I have to split the original case because the tape either makes noise or they do not turn. And install the tape on a case that has the screws so you can open those. I wish there was a way to open original tapes without destroying them.
I have done a few times yes, if they do not turn or feel too tight, hold the cassette from one end and tap it on the palm of your other hand a few times, it somehow loosens it. Yes i'm not a fan of tapes which don't have screws, there's just no way without destroying them.
I will try your suggestion, hopefully it will work.I found a tape box set of a live concert of Bruce Springsteen wich comes with 4 cassettes and they are all stuck. :-(Thank you for the tip.Saludos
Working on that little machine would drive me crazy! no room to work.
This is a great video! You're so cool! Very nice walkman device!
You can get fairly cheap 3000hz test tone cassette tapes that have been recorded from direct drive decks on Ebay. Then its just a matter of using a multimeter with Hz setting or a pc with line in to make the speed right. Its alot better than just using your ears alone...
However be warned that if you are a perfectionist and you get measurements that precise its easy to become Craaaaaazy with how inaccurate your tape decks really are.. I should know.. Ive been there :D
I tend to be a perfectionist when it comes to head alignment but with regards to speed, i'm resisting falling into that trap which you know well haha. As long as the speed is close enough, i'm satisfied :o))
Oh and by the way, you should save that 5 minutes of Tuning sound as a flac file so you can always play it as a steady running reference when you have the cassette in the cassette deck who's motor speed you are tuning to. So you can do it in one step without swapping the same tape between two decks ;)
Yes true, or just running the same frequency from my function generator, which is where I recorded it from ;o)
Audacity for the win :) And there's also Oscilator apps for Android devices. But i guess you already have seen these anyway. Hehe
Yes, thats what I used before getting my actual function generator, the Android app is pretty good :o)
Hello, Thank you for sharing this video.
At the end of the tape the toshiba kt-s1 stops automatically ?
I recently bought one and mine seemed to automatically stop when rewinding and at the end of the video
Thanks so much for the tutorial. Thanks to you I was able to repair my Toshiba kt-s2! You're a life saver! But what was that demagnitizer tape thing you used? What is that for? And is it mandatory? I don't have one...
It's my pleasure, i'm glad you managed to get your Toshiba working!
Over time, the tape head gets magnetized, and requires demagnetizing to restore it, I wouldnt say it's urgent, but if you have a good demagnetizer, it's worth doing it.
Hi, im from Uruguay. 2 days ago i buy one. I oponed and change the belt and is working beatiful but there's something with the volume. It sounds to low. Any idea why? Sorry for my english. Cheers.
Very cool video! Would you believe I have the exact same one with the exact same problems when I got it! The rubber wheel on the forward takeup reel is quite finicky on mine when it is in play mode. These actually have an auto stop mechanism (only for play) that works off of the forward takeup reel, but it depends on the outer part of the wheel rotating as the inner part slips to unlatch the play button. Did you ever see if the rubber wheel is strong enough to engage this auto stop mechanism on yours?
New subscriber. Love the intro and the videos !(: I want one !!
Just purchased one and I’m experiencing the same issue, how did you remove the cassette door to access the spindles ?
I've recently got one of these and unlike my cassette deck forward and rewind don't stop automatically when it gets to the end of the tape and have to do it manually. It does stop automatically when playing and reaches the end but not forwarding or rewinding. Is this normal?
How do you take the plate out? I have a KT-S3 and would like to do the same. You skipped that part in the video.
what exactly did you use to clean the volume slider so I can fix my slider on my grandpa old Toshiba and future projects
The best thing i've found is 'Dioxit Fader' it's a bit expensive but the can lasts you and it does a good job, I wouldnt use any other dioxit variant though, just the one specifically for faders.
Just got one of these. Do you know what size the belt is? I don't wanna pay the insane ebay prices for a little belt!
I highly recommend getting a pack of these: www.ebay.co.uk/itm/35x-Universal-Mix-Cassette-Tape-Machine-Square-Belt-Assorted-Common-Belt-DIY/162493080522?hash=item25d557a3ca:g:pjoAAOSwrhBZAbFp
I just got this machine from eBay. I think it was sitting in the box since the 80s and was in really good condition. I just had to adjust the tape speed thing because it was playing too slow and the belt was fine. My only problem is the volume seems to be super quiet. I read somewhere that maybe I need to replace the audio capacitors. Is this a hard thing to do? Thanks for the video :)
Thanks, and congrats! :o) .. I wouldnt say replacing the audio caps is a hard thing, just as long as you find the right replacements however I must tell you that mine is quiet also, sometimes i'm listening to it while it's full volume and it just sounds normal lol
MsMadLemon oh well if yours is quiet too maybe that's just how these were made. I can crank up the volume on my speakers at home and it sounds great but listening with headphones seems very low at Max volume.
@@Amasloth Hi ... it's pretty loud. Replacing caps helps. Mine had just the buzzing sound with no volume control effect on this buzzing sound whatsoever. I replaced all the caps. Sounds quite good now. Though I'm struggling with slow speed and take-up spindle/pulley/spool. I have tried IPA so many times on the rubber tyre....works very weak for sometime then gives up. And play speed is about 80Hz slower for a 440Hz tone.
What liquids are you using throughout the video?
Where do you get your belts from? I have the same one and my belt is just a bit stretched. (Thankfully it didn’t break and get all slimy!)
You could just get a 30 pack of eBay, did the same with mine, fits well.
Hi! Thank you for your video, great stuff on your channel! Thanks to you I managed to change the belt on this walkman, the old belt was melted and then horribly solidified on the tiny motor wheel.
Anyway, the walkman works but not properly as a I noticed a couple of issues:
1. it plays slowly. when I adjust the motor speed to maximum it is not fast enough and sometimes it's not able to hold that speed. 2. FF and REW don't work smoothly, sometimes I have to press play, then stop and then FF or REW in order for them to work, it looks like they struggle to start spinning (could it just be because of poor batteries?).
These problems seem to affect the way the tape re-wraps inside the cassette case (sorry I don't know how to describe it better).
What are your thoughts about it? any advice? Many Thanks :)
I had the exact same problem with my Walkman WM-F1, it is probably the tape speed adjustment, mine was a bit corroded, I used some isypropal alcohol and some contact cleaner and twisted it back and forth and presto it fixed the speed back up! Hope this helps man!!! 🎉
@@NeoGeo0133 thanks!
Thank you 🎵
Excuse me Maddi,
But I need to ask you a question that will help me on repairing my Toshiba KT-S1 😅
It seems to be in need of some lubrication and whatnot and I'm curious to know what kind of lubricant I should use or which you would recommend me 😊
Also, would lubricating it possibly help with it's wow and flutter or is that a whole different thing?
I would gratefully appreciate if you could help me Ms. Maddi!
Thank you very much and I love your fantastic videos!
Luis, I would be very careful lubricating this, as you can see in the video i tried and it ended up greasing the part i didnt want and i had to drench it in IPA to get the lubrication off... only on the mechanism and only a single drop of even singer oil would do... Wow and flutter is different that can be caused by bad belts or a bad pinch roller,
And thank you for the kind words :o)
Can you still get tyres for theses machines?
What size belt did you use?
thanks ms mad
I have a beloved Rio Karma 20gb MP3 player which only plays in mono. I can get it to play in stereo if I angle the jackplug with a little pressure, but it is a custom socket which the mini-jack sits inside, so I don't think it's possible to replace it. Is there some sort of soldering trick on the internal contacts I can try? Any ideas?
This is a faulty stereo one? i'd try cleaning out the socket first thing with this dioxit stuff or isopropyl alcohol just in case the contacts need cleaning. if i'm understanding right, it seems like contacts have been bent out of position?
it could even be a dry joint, try resoldering and see if that would work.
Great suggestions. I'll take a look. Make sure I'm extra careful. It's made out of quite cheap plastic unfortunately, so the screw holes are ultra fragile now. I'd love one day to make a new case for it somehow, as the software/firmware is beyond awesome, even today.
I really loved your accent! Haha 😁
como você fez pra limpar a borracha o meu também está deslizando?
Parabéns as mulheres, pois dão um toque especial naquilo que fazem.
I have a Toshiba KT-VS1 which I would love to get going again so any help appreciated like knowing where to get the manual, videos, belt, etc.
START WITH EBAY
I can't get my cassette player to play. It starts and then stops abruptly. Any ideas?
Una genia reparando! Y muy divertida!!
God I wish mine had its belt still in one solid piece. Instead it looked like a symbiote was growing inside.
I put 1.2 V batteries in this but it didn't work. I noticed it required 1.5 V batteries so is this the problem? The reason I'm hesitant is because I put 1.2 V batteries in an Aiwa that required 1.5V batteries and it worked fine
1.2v AA batteries will work (rechargable AA batteries are 1.2v and not 1.5v) and I use rechargable all the time anyway, try this with new batteries to test.
Thanks for your reply :)
well done! but we knew already the result... there was a little spoiler as you have used this walkman in a previous video ;-)
Of course you did ;o) .. but it's about the journey not the result lol
Though not everyone did, only those I noticed who really liked this walkman :o))
interesting :-)) another question about the alcohol. why is everybody using isopropyl? it is so much easier for me to find ethanol... is there some advantage using isopropyl?
That is a good question, one thing I know about Isopropyl alcohol is that apparently it doesnt have any greasy contaminants, and tends to thin out grease, if there is any moisture, isopropyl or IPA tends to evaporate it quicker as far as Ive read before... i'm not sure on the properties of ethanol, how it is in comparison to IPA.
And another thing I know is that ethanol I think dries out skin more than IPA, which is why IPA is also known as 'rubbing alcohol', used for skin/wounds etc...thats the limit of my knowledge about them both :o)) lol
:)) that seems to make some sense. I will look in future for IPA . Where do you buy yours? In supermarket? Drugstore?
Whats the song that goes like "disco fever" at the end?
That's 'in the heat of a disco night' by 'Arabesque'
@@MsMadLemon thank you so much!
You should so do crochet videos!
I never got into it to that extent, besides, I have enough creative hobbies already :o)
Hi Maddi,
Great video as ALWAYS!. A couple of comments, not criicism, just trying to pass on my knowledge.
Caig DeOxit is really great stuff, but for faders like the one in the Toshiba, you should use their Fader product. Faders like the one in the Toshiba have a grease that allows the large slider to move across the surface freely. Regular DeOxit tends to wash away the grease and as a result the fader tends to stick in certain spots and not move smoothly.
www.mcmelectronics.com/product/200-204
This product will replace the grease that has been removed.

Second, there is a great product called Rubber Re-Grip that is a chemical conditioner for rubber and is great for the idler pulleys and rubber surfaces. It makes them almost as good as new and gives them a new lease on life. It is especially handy for parts that require much disassembly to replace the rubber. Here is a link:
www.mcmelectronics.com/product/20-230
Third, look into a screwdriver magnetizer/demagnetizer. It is really helpful in working with tiny screws. And working on a towel keeps the wayward screws contained and stops them from bouncing off into oblivion.
www.mcmelectronics.com/product/22-25525
And last, you should look into a FFT program for your computer. It turns your sound card into an audio spectrum analyzer and would allow you to read out the frequency of your tape to set the playback speed. Do a google search for FFT software and you will find many available.
-bob
Nice! i'll look into the rubber conditioner first thing!
I'm going to use a magnet next timefor the tiny screws, at least to stop them going all over the place.
Thanks Bob! That is a lot of very useful info,
The Re-Grip isn't perfect. It works best on glazed and hardened surfaces. If the rubber has turned back into petroleum, it won't help at all. Before trying to replace the rubber, the Re-Grip treatment is my first step. I am not sure what the actual chemical make-up is but it is very strong. I recommend using it in a well ventilated place.
isnt a rta easier when adjusting azimuth?
U can use a Guitar tuner to fix the speed , download an app and u can do a perfect job , Ciaoooooo

What's the battery life on this? I heard it's only 2 hours
I'm not sure exactly but I know it's way more than 2 hours.
MsMadLemon oh, well looks like I'll be buying one thank you!
WHERE DOES ONE GET THE SPINDLE THAT TURNS THE TAPE SO IT PLAYS OR FROM THE MANUAL THE REEL ASS'Y PART NO.25712394
Hi Miss lemon I liked the video but you did not even test out the radio part of the Toshiba . Why not
Thanks... For the radio part you need the tuner cassette cartridges which I unfortunately don't have.
@@MsMadLemon ok thanks for the explanation i wasnt aware it needed that
