I am a cassette deck lover and own a couple of dozens of them. I also own and repaired two used WM-D6C for my own fun and use. I have to say their spec of 40-15k Hz FR is not telling you the whole truth of how it sounds doing recording. They are impressive and their Dolby circuits are great. Your work on this is thoroughly enjoyable! Thank you!

Great fix, still love your channel after all these years bud, keep up the great content

Interesting video. Today, I finished working on a Sony slv-se80 which was dead and not powering up. I’m pleased to say it’s now fully working! My first time fixing something. Thanks so much for your work which has been of great help!!

Another fantastic diagnostic anf fix. Experience surely counts for a lot. Good job

Got my walkman back in shape following your vid. Thanks!

A well-preserved unit, well worth the effort. Good job.

Fantastic video. Followed this to repair my WM-D6C. Mine was badly clogged up and took a couple of hours to finally release the mechanism. Those washers are no fun to put back on! Thank you for this video.

Just got a D6C from ebay & it had this exact problem -- thanks man, you're a lifesaver!

Outstanding video - described my problem perfectly. Be proud of your work! Thank you!

Had the same issue with mine, and now it's all fixed! Fantastic video, thank you so much

I only just found your channel, and watching you work on this is amazing, enjoying, and very informing, despite my meagre age of 26 I love analogue tech and it always interests me on how to repair stuff, and I am very happy you make these videos to show what exactly goes into doing that. Ignore the trolls, they don't see the hidden worth of you showing this for free.

Beautifully done. Same thing has happened to mine and now I know I can fix it....Thank you.

Probably the best walkman ever made, i would love to own one of these bad boys one day

Thanks so much for such an informative video, I now feel I can attempt to repair this exact fault on mine

I had a Revox G36 with tubes and was happy with that until I bought this Professional Walkman. I still listen to the the live microphone recordings I did. Cristal clear AND NO NOSE.

Great to see someone whos in the know on these

Really nice video. I enjoyed watching you repair this beautiful piece of vintage audio equipment. I want to get my hands on a Sony WM-D6 someday. Greetings from Bulgaria.

Good fix again! I hate those small washers :D I miss some, and never found again.

I have 12 of these babys b4 the insane price hike, love them

Loved the video. Had my D6c around 4 years now and it's really got me back into cassette tapes. Amazingly capable machine in every respect, half the time it's plugged into my Hifi, metal tapes in Dolby C sound incredible.

Same Always. Beautiful.

I remember when the first Walkman came out and some guy I knew bought one in Japan and brought it back here to the states. Everyone was so impressed how something so small could produce sound so big on those small headphones. What year was that? Early 80's in there somewhere.... I have the early WM-F1 which I believe is the first one to have FM radio analog tuner. Digital is obviously better, but I have always been fascinated by magnetic recording machines of all kinds since I was a kid.

Dave nice job, I bet the subscriber who sent this Sony Walkman to you is an engineer, because of the methodical way he explained the problem topped off by how he package the unit. My guess would be he worked as a design engineer for the atomic power industry.

Such a nice condition unit :-) Smashing repair dave, Not easy to work on that brand of hell lol. Full of tiny parts just wanting an excuse to ping off into another universe lol. I really really hate the tiny wires that are just ready to snap. Taking pictures with a phone has often saved me, not just electronics. You made one mistake.... No mug of coffee to slurp :-D.

Dolby B and C, super nice.

Nice job, sir. This unit was obviously well taken care of. Hope you have given it 4 more decades of enjoyment! By the way, I enjoyed the David Grisman?

I've tried the rubber rings from eBay. They have excellent reputation and many people swear by them. There have been many reports on TapeHeads that they work very well. However that was not my experience. The original rubber ring was working perfectly and my W&F was as expected (around 0.04%). The eBay one was way higher than this. For the WM-D6Cs, the rubber ring is not necessarily a replacement item, as they hold very well, unless they were left in play with pause and the axle made an indentation. Good repair!

Found mine in very poor condition but for very cheap. Unfortunately the infamous CX20084 chip is bad in it so it goes super fast. Oh well, not paying more than 100 bucks for another IC but nice aesthetic piece. Got an 80s 3 head marantz for way less than the chip instead

Maybe one day you will work on some of those small flat, side gun CRTs. (sony watchman, door interfon...) They are so cool.

Morning Dave .... These things were an utter bastard to work on with all those thin wires barely attached to the board !.....

👏👏👏👏👏👏

Great fix. Would never thought it was that wheel being seized. By the way, I just bought one, all buttons are working, but when pressing the play button, it can go all the way down, but can engage, it goes up. but when press record button, the play button can enage. What do you think can be wrong? Please help.!

Great content, i wish to send you mine to repair the fw rw issue, possible ?

Do you know if the same belt drives the FF / REV and the Play?

Hello sir I have a quick question < I have a sony walkman WM-D6 , when I put battery on it after so long in storage, it briefly sounded when I played the cassette , but the sound faded away ,and now no sound at all, is this a sign of a capacitor breakdown , that need to be replaced after so many yrears? it play when I press play. rewinds and fastforward. Please help.

I can well remember cursing Sony and all the other brands for making the walkmans a real pain to work on. Where i worked were authorised Sony dealers, but if we wanted the special extension leads and jigs we had to pay for them, only the Sony repair centers got them for free in the UK. Most of the issues were mechanical as the customers would use them on the beach with sand playing havoc once it crept onto any grease.

Is a good stereo recorder whiout mic inside is external condenser microphone

Hi there, I have WM-D6C too. This morning I found out that one of the headphone channel is gone. Could you advise where can I check it? Thanks

I got one today, and the seller says it worked off adapter and batteries, but has the speed issue. I couldnt get it to turn on with batteries at all. I dont have an adapter, or want to use one unless its the right one. I get 5.7v on the battery holder connector pads, but when in the player im only seeing .61v where in comes into the board from the battery holder. This seems kind of odd since it isnt passing through any circuits before that point, i dont think. Someone said the dc-dc needs to be bridged but i wasnt sure. Any ideas? I also have a genuine CX chip which another seller had extra from a few years back. He had used one in his broken one and got it working fine, so the spare one should be OK. Hopefully.

Where can I get an electronic technician certification? Any recommendations?

I have a Sony WM-D6C that my child recently dropped. It rewinds & fast forwards, but doesn’t play. The battery light comes on, I hear tape hissing, but when I press play…it doesn’t turn to play. Please advise or could I send it to you to repair? Thanks! 🙏🏼

Hiya , have you ever worked on a sony walkman tcs 300 ? I have no ff or rew either but the set up mechanism is slightly different from this unit but every thing seems free enough but I just can't get it to work Kind regards Paul

My WM-D6C that I pulled to use today after it's been stored for over a year has no FF or RW, At least now I know what to look for, Is it a good idea to replace the belt and tire while in there or just keep the originals as long as they are working fine?

I have the small unit have been using it the past three years. But now it won’t do anything. Gave it new batteries and it’s not doing a think. What might this mean?

Dave, have you ever worked on clocks, a mechanical music box, or grammophone? I bet you used to take apart your toys as a kid just to see how they worked, I know I did. If it was powered by a spring or battery it came apart.

I have 2 WM-D6C, one (the earlier unit is fine (but doesn't like the battery- despite cleaning contacts). The other, however (a later model WM D6 (SN 25058) with 2 earphone sockets) has a mechanical problem - the head plate won't engage with the capstan - leaving about 1 mm between the capstan and the pinch roller, and as a result the motor won't run. But I can't for the life of me figure out what might be stopping its movement. Any ideas? Stop/eject mechanism works.

my late father was an opera singer in his youth and used one of these to record cassettes for auditions. it was left to me and rewind is not working. ill have to try this out

Hello, I have problems with my Video Recorder. It doesn't wanna play my tapes good and it has really bad audio with low volume. Only the first seconds it plays, it plays good audio. And if you stop the tape and play it agian it has good audio for a few seconds agian. It isn't the Vhs but the Recorder. Can you please help me with this? And also it chews on the tapes.

This was very interesting, thank you!

Can i send my unit to get fix? When pressing plat button it stop right away. Forward stops after 5 seconds. Do you still repair DC6

HOW DO WE CONTACT YOU ? LOVED YOUR WORK !

How much to get it shipped to you to fix and how to do it

„Germany is right next to China“ Yes, recently. And not only in terms of the quality of work. BTW: The washer lying freely in the housing (above the motor) triggers me 😉

is it raccomandable to replace springs lke the one involved? or it's not worth

good evening, I can ask, please, what do you use for those magnifying glasses (magnifying glass), thank you very much, I will be very happy for the label, thank you, whether

WALKMAN!!!!

I have a D6C on the fritz. I wish I could find someone in the US with repair experience on these. It’s too valuable to risk shipping internationally.

Ha ha way way way back when ( old timer now ) Working for RACAL I can remember a cartoon someone had cut out of a tec mag and put it on the notice board. it shows a design engineer saying I know let's hide the last retaining screw behind the main circuit board. That will pi*s them off regards from over the pond

Hey 12 Volts I'm Located in ON Canada and I was wondering if you take on jobs? I've got a Sanyo JJ F6 that I believe needs a new belt any chance you could work on it?

Mine has the speed chip fried. Wonder whether it is available anywhere..

would it be worth it today if one wants to buy this professional Walkman to play and record high quality cassettes? is also the best in the world? also problems can get out? has problems with capacitors?

It seems to me that the belt is now full of grease or oil. That cannot be good, right?

この動画のウォークマンに取り付けられている録音・再生ヘッドの形状は、純正パーツ「S&F Head」と明らかに異なっている。安価なパーツと交換されているかも知れない。

Hello...I wanna send my wm-d6c for repair. Ty

"can't do much about that" :-)))))) When these are Properly serviced, they have a W&F of 0.04%.....

Wait.. this exists? Edit = title is wrong

Just about impossible to get the Sony CX20084 speed chip anymore so only use batteries fellow D6C owners :) Using the wrong power adapter or reverse polarity will blow the speed chip and the DC to DC converter which is a fun job to fix but the speed chip next to impossible to get. Don't buy the Chinese copies they don't work.

Part made in Germany from Chinesium. .

Thanks so much for this video. I am trying to fix my 28 year old WMD6C as it keeps chewing tapes after a few seconds of play. I have a new belt to replace, but I suspect the gear has seized too. I'm visually impaired so working on tiny components is a challenge. But this video will help a lot. I've already opened up my Sony previously, but wasn't too sure what to remove to get it fixed, so this helps a lot. If you're ever in Derry in Ireland I'll get you a pint to say thanks for the video. Ignore the unskilled trolls. They have zero industry experience.

@12voltvids I Have one that is in need of repair .It won't play ,rewind or fast forward. .I Live in New Zealand can I Have your contact details and send it to you ? Best regards From NZ.

Love your video can u send you postal info so l can send you my repair pls

That voice over in the intro is just weird. The VO and the music was overlapping each other that I couldn't hear what you're saying. And then the intro editing has nothing to do with the VO, it is confusing.

Isn't everything "next to china" anymore? Lol

I don't understand peoples need to correct anothers repair methods or work practices. If you don't do it their way, well you are an idiot and they feel the need to tell you so. If we were all made out of the same mold then perhaps we would do things the same way. Anyone who was, or is married, knows what I mean. I watch many different KZfaq channels on electrical repair, and each tech is diverse and different, as snowflakes. Many of the arm chair quarterbacks out there only repeat what they have heard second hand from other content creators and have not worked in a production shop where things need to move in a timely manner, or even worked in the business on their own. I have about had it with the "you got to change every capacitor" persons. If it is mine, and if it is not in a critical circuit I will change it if it is one that is known to piss on the board or when it is symptomatic or fails, thank you very much. Not counting those wax paper caps and the like.

Germany and China are not even on the same continent hah, Germany is in the center to west of Europe and China is on the far east out of Europe's border, they are almost of the opposite sides of the globe :D
