Teardown of the World's Thinnest Portable CD Player in 2004

[@ultimateelectronicfun1864]

HighMAT is a media format that was developed by Panasonic and Microsoft for CD authoring with music/video content in the Windows XP days. The HighMAT switch is probably for CDs with the HighMAT format.

[@ultimateelectronicfun1864]

@Bishop Zain I see

[@paquitoperez2116]

From Panasonic User Guide: HighMAT is a new format management standard used forwriting audio/video and still image files to CD-R/RW. You canadd track titles, artist names and record playlist settings whichallows you to easily search large volumes of files for play.You can play discs recorded with WMA/MP3 audio files on thisunit.≥You cannot play discs recorded using Windows Media Audio 9Professional/Lossless/Voice

I have the Panasonic SL-CT800 and I think it's still working.

[@kilospl]

Sony had a thinner CD player 2 or 3 years earlier. The D-EJ1000 is 13.9mm thick, the Panasonic one here is 14.4mm. 😉 When it comes to rechargeable batteries, there is no special magic here. These are ordinary gumsticks batteries used in many different portable devices.

[@RobertNES816]

Wow makes me wonder what's inside my Panasonic SL-NP500. One of the few things I noticed was the difference in overall clarity with newer players. While the shock protection and battery life went up dramatically over time, the sound quality took a turn for the worse. I mean overall filtering improvements were few and far between in the 90's but the way the highs,mids and lows were presented really took a dip. As is manufactures started to favor bass heavy tones instead of a clearer more balanced audio signature. It was for this reason that I never gave up on the older tech since I knew Panasonic and probably other manufacturers took great care in designing and engineering their audio amps and accompanyed circuitry.

What was the model number of the rechargeable batteries could I get them on eBay for a cheaper price?

[@ELECTROHAXZ]

Thank you for not monetizing your videos! Ads are suuuuuuuuuuuuuper annoyyyyyyyyyyying!!! :)

[@IunahYT]

ELECTROHAXZ just download adblock. Or seven adclear on android

[@piotrciesielski8937]

iRiver SlimX iMP-550 was even slimmer! :)

[@DJCowcat]

i made a modding to my ct810 I replaced the output coupling capacitors the original value was 150uf I replaced it with 220uf(C706 C705) for more bass like sony I also stacked a pair of 10nf capacitors on R708 R 707 to trim a little bit trable. you can search the service manual for it. so what i did was making ct810 sounds as bassy as sony cd players

[@sethcaine3659]

did you put it back together successfully and did it work? also.. you said that you hear a lower quality encoded reproduction of the cd? so is the sound quality low? how does it compare to say the sl-860 interesting vid, thanks!

[@RagedContinuum]

I have a sl-ct700 and had an sl-ct810 in the past and sold it.. I thought the 700 sounded better tbh, although ti might've had the same anti-skip technology

[@RagedContinuum]

the 810 had different DSP version though

[@dannyho9076]

the thinnest was sl-ct820,its still with me working well till now just tested.longest batt life ever 220h playback.

[@mariaelenapoubeato]

I broke one of my batteries contact, do you know how I could put it back?

[@johnd942]

If that perfectly good CD player has been ruined by this Tear Down; it's a crying shame! It could have been donated to someone less-well-off.

[@forrestcowcat]

hey i have the service manual for it. you want a copy? also replacing the coupling capacitors between amp chip and earphone jack with 6v 220uf, then the bass sounds like sony models.

[@McCoyHomestead]

Did you put it back together and make it work again?🤪

[@theycallmejpj]

mine has recently developed a fault. when you press play the green lights come on under the play and stop buttons, and then it changes to the led pattern like when it's charging, and after a few seconds it stops. the cd never plays and the motor does not function. I scoured the net and bought 4x replacement batteries, and still no joy. works perfectly when connected to the mains. anyone have any ideas?

[@davidbolha]

Make a (720p) video (with good lightning) about it ? 🤔

[@dannyho9076]

i got ct820 model more slim than urs still excellent working condition.great vintage walkman

[@ericabreeze539]

where is the radio on the cd player

[@didgeteria9068]

That is not the thinnest CD player . Sony DE-EJ 995 and 1000 are the thinnest. Edit : the Sony I mentioned are even older .

[@PCUser1024]

In 2004, the thinnest portable CD player was the Sony D-NE20, with a thinkness of 13.1mm.

[@jeremifrancisco1]

Is that the thinnest portable CD player?

[@jeremifrancisco1]

@Andrew Battersby Thanks for your response. Is it true that players with 'anti skip' loss playback quality? That has me intrigued.

[@jeremifrancisco1]

@Andrew Battersby I see. Thanks for the explanation.

[@snyggmikael]

I remember Sony making a thinner one that was almost as thin as 3 or 4 disk stacked.

[@jeremifrancisco1]

Do you remember the number model of it?

[@snyggmikael]

@@jeremifrancisco1 D-NE20, however I remember it with a bit of over exaggeration. It was 1.3 cm in thickness and was released 2005. Hm... or perhaps I was right, 4 disks is probably something like that no? xD .. oh well pretty thin either way hehe

[@jeremifrancisco1]

TH3MS thanks flor your reply! I'm looking to get one portable CD player. Only thing is, the Panasonic and Sony are expensive. So, that kinda sucks, haha.

[@kangjhha]

the sony D-E01 or D-EJ01 depending on where u lived is comparable may be even thinner but from 1999 and there is also the D-EJ2000 that was thin as a cd jule case back in 2002

[@fernandofernando7586]

Very good!

[@collinperry1494]

Cool CD player

[@davidfarrell7318]

i still use a sony personal cd player and i think it sounds amazing with good quality headphones they say cd it dying that amazes me never used downloaded music ever and dont intend to enjoyed your video.

[@strilight]

I wonder what the world's thinnest CD player would be if they got rid of the 3.5mm jack?

[@Djluv5]

i got my sony dej2000 in 2003 and it looks slimmer than this one.. so i dont think this was the slimmest in the world..

[@TheUbuntuGuy]

+Djluv5 Well according to the spec sheets, the Sony was 1mm thinner, so you are indeed correct.

[@tttttt9682]

That was not MP3/WMA player ...

[@john005_]

thank you for the teardown, it gave me an idea of how I can repair my diskman. Would you know by any chance what could be possibly causing my disks to skip?

[@backi480]

Sony 1.34 cm ... Panasonic 1.44cm ;)

[@LeonPajuelo]

I've got a Sony D-EJ925. It's really thin, I'm not sure, probably 1.6mm

[@成興桃]

In fact you can't assemble the parts in the case

[@guitarboyjeff]

It was the Nintendo Switch that fell!!! 😝

[@guitarboyjeff]

I’m sorry but the tech inside me cringes every time his fingers move dangerously close to the lens!!!!!! 😱😱😱😱😱😰
