- เผยแพร่เมื่อ 4 ต.ค. 2024
- After successfully repairing the Toshiba KT-S1 in the last part of "The Walkmans", the next in line for a repair and restoration is this Sony WM-4 in that gorgeous red edition! I open this up and discover more than I expected. I attempt to repair the stuck buttons and free the mechanism from this jam. I then sort out a very crackly volume control using Dioxit. All while listening to Amiga Mod remixes on the previous KT-S1 walkman.

The walkman (quoted from Wikipedia)
"Walkman is a Sony brand tradename originally used for portable audio cassette/tape players in the late 1970s. In the 2010s, it was used to market Sony's portable audio and video players as well as a line of former Sony Ericsson mobile phones. The original Walkman actually introduced a change in music listening habits by allowing people to carry recorded music with them and listen to music through lightweight headphones. Owners of the Walkman were able to take back their "lost" time, commuting for example, and turn it into a pleasurable experience, or add a soundtrack to their urban surroundings.[2] It was the privatization and personalization offered by the Walkman that led to its success.
The prototype was built in 1978 by audio-division engineer Nobutoshi Kihara for Sony co-founder Masaru Ibuka. Ibuka wanted to be able to listen to operas during his frequent trans-Pacific plane trips, and presented the idea to Kihara.[3] The original idea for a portable stereo is credited to Brazilian-German inventor Andreas Pavel.[4] The first Walkman was marketed in 1979 in Japan, using the name Walkman. From 1980, it was known as the Soundabout in many other countries including the US, Freestyle in Sweden, and the Stowaway in the UK.[5] Advertising, despite all the foreign languages, still attracted thousands of buyers in the US specifically.[6] Sony President and co-founder Akio Morita hated the name "Walkman" and asked that it be changed, but relented after being told by junior executives that a promotion campaign had already begun using the brand name and that it would be too expensive to change.[3]
The names "Walkman", "Pressman", "Watchman", "Scoopman", "Discman", and "Talkman" are trademarks of Sony, and have been applied to a wide range of portable entertainment devices manufactured by the company. The name "Walkman" was based on its precursor, the Pressman tape recorder. An initial prototype of the Walkman was in fact made by replacing the monophonic recording circuit, head and speaker from the Pressman with a stereo playback-only head and amplifier.[7] Sony continues to use the "Walkman" brand name for most of their portable audio devices, after the "Discman" name for CD players was dropped in the late 1990s"
Amazing cinematography! I have just started getting in to Walkmans and repairing them.
Oh Hello There! What u doin in my swamp?
there are others out here repairing old stuff, but no one ive seen repairs with random stuff they find. Just a little bit of creativity in the monotony of tech. truly awesome
It's nice to know there are people as insane as me - using wall hooks and other scrap bits of metal to make parts that are missing! I laughed my ass off when you pulled that picture hook out because I used EXACTLY the same hook to fix something last year lol. Genius! =D
LOOOOL - then you found the bit ;)
Okay, i'm glad i'm not the only one who is nuts lol! ..But those hooks are so useful! with things like this! ;o))
That freakin bit was just the cherry on the cake lol
@@MsMadLemon I have walkmans to but I wont deal with the first one it is fun but much to difficult for me I prefer ones iwth touch buttons I also got a cassette player added back into a new car.
Did you ever see the sony walkman that has a dual head mechinism I have one its really nice. Then the head does not move for auto reverse. It is also green I will make a video sometime. I subscribed to you as well.
Is it really crazy tho? People around me, myself included, do it all the time.
A woman who loves and repairs Walkman's ?! OMG, marry me ! 😍
I think you are on a highway to disappointment trying to stop brittle old plastic from cracking more, but the obsolete tech gods are smiling on your efforts!
Brittle old plastic cracking?
In the late 80's I was seeing WM4's at Goodwill stores for $2-3 and had a small collection.
Ended up giving them all away, I think, because they never seemed to stop working!
I love the professional diagnostic! The grease and belts love affair with the mechanism crying because it got cheated on!
You are just too fun...
I could listen to your laugh all day...you make me smile and blow my mind all at the same time watching you just tear open these Walkman players and get them going again. That Toshiba is the same model my little brother had when he was in Jr. High. He got it for his Birthday. Still worked last time I remember...✌
I got my own repaired too just now, with a belt change and pot deoxiting too. Your video was just invaluable to showing me the right way to go about it. Thanks so much!
Thank you for posting this. Our family's first Walkman was a WM4 (silver, not red). I found this video by a search of the model #. If you think the tape speed is off, you can adjust the pitch pot while it's running (and not all apart) by inserting a jeweller's screwdriver in a slot at the top of battery compartment.
Wow, I was just rearranging two picture frames, I used those same hooks.Happy to see your hands again 😀😀✋✋✋👍
You blew my mind when you opened that taperecorder looking box the first time. I was like, what the hell is going on here, even though I already saw it in your other videos...It just looked so realistic from the distance.
Haha it really does actually! When I first saw it I was impressed!
dayum....actual mechanical buttons...you press it, stuff moves, and something 'happens' internally to give you the effect of the button
xD
a rare sight nowadays, a cool sight too
I recently picked up a Sony TCS-48 and I'm in love. It's a Cassette corder and it's good as new!
Now i want that black one in the start. Have to stop looking, otherwise i cant deside!
You found the piece! That's a real Mr. Bean moment there.
Tell me about it!
Just started watching your videos last night and enjoy your excitement and enthusiasm. How ever I have just one question. What is in that tea.lol.
Damn now I want one of those Maxell tapes to watch the wheels turn
Very happy you managed to fix the big red bus. The door being jammed, it must have been a relief to finally kick out the passenger. Awesome music, never heard any of those remixes before, and if anything, the bus sound fuller and richer in sound than the silver one. Perhaps it comes with a built amp? Its funny, whenever I see caps in a video now, I instantly imagine you going to work with your de-cap gun. That things is a menace!. btw, someone posted some excellent Turrican music into the Lemon Hallowed Guitar hall of fame thread today, which you must check out. :) (its in the games section)
You've had a thing for that red bus from the beginning havent you ;o))
I didnt give them a fair comparison in this video as Toshiba was playing quietly throughout the video.. But yes the Red bus is much louder than the Toshiba... sound quality wise I think Toshiba might have a slight edge over Red bus.
Hahah there's more recapping to do (God help me!)
I must check out that guitar hall of fame thread! I still need to have a go at the two games, i'm going to suck at this round lol i've been practicing though. I got further in Lionheart than i did the first couple of times I played.. the controls feel a bit stiff as in the way the main character moves is awkward. Something a little off about it.
ha-ha, great to hear it. I know Lionheart is not really an easy game and Tetris can drive me crazy! Yes I have a thing for the red bus, it stood out among the crowd and said "pick me". It is so amazing to see you repair things, as each time I think it is beyond help, but each time you fix it. I dont know about green fingers, but you must have solder silver fingers or something. :)
Great job Maddi as always.
Nice work!! Love it when a plan comes together, and that feeling of coming out of the other end with a nice working unit is a great one. Ingenuity is sometimes needed and yes, hold on to that stop plate just in case... :D
Got my first red sony head phones from 2014
Lol. You have the Xenon 2 music playing! That's my ringtone. Very confused for a bit there 😁
Hi, I got a Sony Walkman WM-4 like the one in this video, but apparently, the original owner let it fall or something, and it doesn't have the "stop" button, do you know where I could get a replacement one? or if there is a workaround , Thanks in advance :)
What a lovely ambassador for audio happiness you are isn't your little Marantz a cute bit of kit !, do keep up the good work much happiness be yoursThankyou for your wonderful videosKeep them up
I love that Marantz amp, or as I call him Señor Smiley ;o))
Thank you|
Bravo! And yes God does have a sense of humor. 😃
...sometimes even a bad sense of humor.
Really enjoying your channel I find it relaxing and informative thank you
My pleasure! And thank you!
I did not know the model WM-4. That seems to be a very rare model.
Amazing work
You just fixed the same exact model of walkman i used to have in high school... with the same exact problem! (no, i didn't stuck in FF and REW, but the STOP button died like in 1987... after a drop on the floor) Sould i try find mone and fix it?
YES!... its not a hard fix, if it's got a piece inside rattling around, it may well be there already
Nice video, where can I find the Amiga mix tape? I really liked how it sounded
I'd love one but these are heading for 40 and may be a risky purchase?
It will most likely need new belts, if you restore it well then it will last you, have a search for one that's in good condition :o)
You’re a funny lady :D Looks like you got a free cassette with that one.
Where did you get your shoebox cassette player metal case? I need one!
I'm not exactly sure where these are made, I got mien from ebay but I just saw one here: www.webbsdirect.co.uk/cassette-recorder-tin/?SKU=901820&gclid=EAIaIQobChMI-Zb34Ivy1AIVxgrTCh2cfwIREAkYAiABEgJQNvD_BwE
Nice video as always, congrats withe fixing it :3
Subscribed! Great Content on your channel For Lockdown time...😉
this is a nice tutorial! silly question, do you have a playlist with the songs of that "Amiga" cassette? I wanna make some old school game OST tape too! saludos desde Costa Rica!!
Not a silly question, i've been asked a couple of times and answered a while back with this post: (The first comment has the the tracklist ) : facebook.com/msmadlemon/photos/a.140041719997146.1073741828.140022089999109/168534427147875/?type=3&theater
MsMadLemon Oh!! muchas gracias!! :D
Magnificent work there ! I think I will get a KT-S3 next month.And by the way your voice is so cute~
Using that picture frame hangar mount then finding the part, you must have been so miffed lol...
I was, but at least I got to be Macguyver for a few moments lol
Can someone please inform me how you can change the playback speed? "Or as she said it brighten up the tone"?
I know your secret - that's not tea. It's quite a pale brew, perhaps a single malt. Glenfiddich ? No wonder you giggle. LOL
A nice gentle video full of lovely gubbins, my favorite. Where did you learn about repairing things like Walkman's or is it in the genes.
I think the giggling is in the genes as I don't drink ;o)) lol
Electronics and repairing stuff, I just dive in, explore and learn.. Thanks! Glad you enjoyed the video!
The fact that you are home taught is even more impressive.
Just brewing 3 gallons (13.5L) of home brew. Good stuff, puts hairs on you chest - so the wife tells me. lol
Young lady you are a breath of fresh air on TH-cam. Giggles an all.
This is fantastic! I just found your channel! Thank you so much! :-)
Nice video :)
Thx for sharing
Thank you! ;o)
No I did not forget.... enjoy! ;o)
th-cam.com/video/5dIWjg5loqA/w-d-xo.html
The spring that should hold the Horizontal mech that snaps accross the STOP button is missing
Cool! another audio repair video :)))
I'm learning how to DIY from your videos. Hopefully I can be good enough to start doing preamps and crts which can kill a person.
I'm sure you have the sense to read up on safety first, since you already know it can kill a person.
just dug out my old WM-4 and put batteries in...It seems to all work ....The gears and rollers all turn but won't turn a tape inside cause all cassettes are old now and don't move that easily..The tape head cleaner ran ok.
. I imagine the belts are shot. Where can I get some belts? Ebay doesn't have any specifically for the WM-4
You could get some belts on ebay. They Don't need to be perfect for it but you could always ajust he speed of the motors. Or find a similar size belt
Nice video, I'm starting my own project with a wm-4! I kind of want to add a Bluetooth receiver parallel to the tape with a switch to switch between tape or Bluetooth. That way I'd have the option to stream music from my phone to the Walkman, giving the illusion I'm more old school than I actually am ;) Was just wondering, what track is your intro music from? It sounds awesome! Keep up the good work :)
Hmm interesting project, would like to see how you you go on with this!
And thank you! the Intro/outro music is actually one of my own which I wrote back in 1998, thank you! :o)
Sorted v r tone today, speed is correct, although I noticed that some of the high pitched sounds during playback are not resonating correctly, is there anything that can be done? Great video
hi ive just begin watching your videos, yore a very interesting lady,
I notice when are changing belts!, the condition was onad the basically melt,
but a little tip, there's a product called rubber renew, which obviously can't help mthe belts
but will be good for the wheels with the rubber rings around them,
and don't forget old capacitors will affect the play speed, ;-)
Is there any particular kind of oil I should be using for the motors?
i just used Singer sewing machine oil
Where have you been whole my life? :O
Are you educated in a field related to electronics, or do you work with electronics ? How come you can do so much at home, I'm very impressed.
Thanks! I've just been tinkering with electronics since I was 10, i'm self taught really but reparing amps etc is a recent thing. The more you do the more you learn :o)
MsMadLemon oh, the "since 10" part really explains it. I really wanna get into this sorta stuff and channels like yours are great. Keep it up! :)
My Sony TCS 350 looks almost like your red Sony :] Only with added Microphones. But mine misses the belt holder on the back. Are you planning on changing the capacitors too some times?
Indeed, it does..Replacing capacitors In this wm-4? well it's not so urgent, I have a few things on my list that need recapping, so for now i'm leaving it as it is.
Hi, I have just bought a 2nd hand wm4 walkman and replaced the drive belts with good fitting replacements. Play and fast forward are fine, but rewind works only without a tape inside.
How should I repair this?
Also how do you turn the 'v r' control to brighten the tone, mine doesn't seem to move?
Thanks
I just got one of these at an auction, for an exceptionally reasonable price. Do you have details of the demagnetising cassette you are using? I would love to get one. Thanks
The only thing I know about it, is that its an electronic one from Radio Shack.
I see a lot of them with brushes and a "demagnetizing fluid", but I can't find one like yours that actually looks like it makes a difference! I'll keep looking, Love your videos!
"Demagnetizing fluid"? what the freak is that?! lol.;o)) .. Ah brushes, its a head cleaner, the fluid is just Isopropyl Alcohol. Yeah i'd only get electronic demagnetizers, I even have a second electronic Sony one somewhere, but I prefer this one.
I've cleaned it up with Isopropyl and cotton buds, and it's already sounding good. Do you put a battery into the electronic demagnetizers, or are they powered by the motor of the player? Thanks and keep making more videos!
no the demagnetizers have coin type batteries you have to change.
Nice! glad you got it sounding better!
I have a question about tge very same WM-4, I replaced the belts but the speed is too slow. I'm wondering what could be the problem?
Two things, make sure the belt is not to tight if you've used a non standard one, and also there is a speed adjustment pot in there with which you can tweak the motor speed.
MsMadLemon where can I find this speed adjustment pot?
14:58 the part that says "VR" on the board is the pot.
15:43 you see me turning it there.
Great job! Can I ask where do you get your belts from? I'm working in a pioneer ct-200. Thanks.
Thanks Manuel, yes I actually just get them from ebay, they sell them in packs of 30 or 40 bands of different sizes.
sorted rewind today (see previous comment), but unsure how to adjust VR control to brighten tone, please help
get the SONY TPS-L2!!!
Do you know what the original ac power adapter this unit uses?
Does the demagnetizer tape cassette work very well compared to one that plugs into the wall?
I've never tried the mains powered one, i'm a little wary of it since apparently there seems to be more chance of magnetizing the tape head with it.
MsMadLemon I have read the same thing happening. Have you proven to yourself that the cassette shaped one works very well?
Honestly speaking, i've heard that demagnetizers make a difference hence why i use this one whenever restoring or before recording a tape. However I havent heard any significant difference in the sound quality itself before or after demagnetizing.
MsMadLemon Thanks. I have read that magnetised heads can cause reduced treble response and partially erased tapes on playing. Demagnetisation would indeed be beneficial. Need to see if those cassette form-factor demagnetisers work well as they would be very handy!
What's in that tea you're drinking. Lol
Lol! you're convinced i'm snorting something or other ;o))
Either that or you're dating Batman's enemy The Joker. Lol
Some are addicted to drugs
While others are addicted to walkmans
I have sony wm ex 610 that the dinamo only spin a couple second then stop. Can u tell me whats wrong with my walkman, it the problem in dinamo or something else? Please
interesting...what kinda glue you used to fix the metal part to the button?
If I remember I just used standard super glue
Sony vtc6 is for sale, how much is the price?
good job greeting Brandon.
Thanks Brandon! :o)
I guess I will have to forget about that red Sony Maddie, since you fixed it. Good job! you keep amazing me with your electronic knowledge.Saludos
Hey I was listening to that.lol.
Hi Maddi. You are making great videos. I love all of them. Can you tell me where you got the package of belts? I have a AIWA PX997. But I can't find where to get a belt for it. Greetings
Hi there, thank you!
Actually I get the belts from ebay, in bundles like this: www.ebay.com/itm/120-PCS-40-130mm-Mix-Cassette-Tape-Machine-Square-Belt-Assorted-Universal-Repair-/302142095704?hash=item4659128158:g:lUIAAOSwdzVXwcR8
How size belt for this walkman?
What kind of oil is that?
Вы крутая!
Merhaba efendim sorumu war sony wm d6 vites süreci sorunu var Türkiye ye kargo yaparmı yaparmı ücretini ibanınamı havele yapacaz
Maddie, been meaning to ask : how good is the sound quality of the WM-4? Is it leagues behind the WM-D6C? or is it somewhat close? Thanks for your thoughts, there's one locally and I've been muling over picking it up.
It's really good I have one that I use all the time and it's never given me any trouble
Halo Meraba I want to buy sony vm d 6 device do you have it
Hi, what solution do you use to clean the walkman???
I would use soapy water on a soft cloth or sponge, anything harsh like IPA would take the coating off.
My mom had a red wm 4 in 1984-1986
She threw it away😔
hello man can you help me i want to buy sony wm d6 waltman device
was the motor running before repair? i've got a similar mechanism sanyo walkman but the motor was not working at all, so have no idea what i should do first, any recommendation?
Turn the walkman off and try to power the motor by using a 3v battery, if it spins it mens the motor is fine, if not, possibly a replacement..... if the motor spins, it could be a dry joint so resolder the motor wires on the circuitboard. (best to always start with the simplest things when repairing)
Ms Mad Lemon thanks for the input, hopefully i could figure out how to connect the battery to the motor directly for trial.
@@MsMadLemon thank you very much for the input, but i don't quite understand how to test the motor, possible for you to show a video clip for more please? greatly appreciated in advance.
I want one
I think I'm falling in love with you. You're unique in this world. Kisses from Argentina!
Some good pictures herewww.petervis.com/walkmans/sony-wm-4/sony-wm-4-inside-view.html but not of the stop button mechanism it also has the correct belt sizes .I have a working grey wm4 said to be one of the loudest walkmans .
I did notice that, it is pretty loud and I was surprised. Thanks for the link!
I read somewhere the WM-4 is much louder than many models because it uses 4 batteries instead of the usual 2.
I have this walkman bug in silver
I never thought I’d find these videos so entertaining, but something about her finding that missing piece after using a replacement made me laugh for 7 minuets straight...
Como extraño temer uno , y lo pero es que ya es muy difícil conseguir uno y mas de donde soy todos los botaron sin pensar
