Philip CD104 CD player, changing belt and removing Oversampling

[@waheex]

As an Update, I decided to reverse the oversampling mod. This was after speaking to those with much more experience with these machines. The mod can introduce unwanted Rf signals into the audio stream due to the removal of the filter.

NOS mod does not cause any problems...... I use all my cd players and dac that way for more then 10 years..... may be can cause problem with some poorly build amps.... for me never had any....

@@cskabosBut did you measure? It's not a matter of 'I don't hear it so it is not there'.

@@puciohenzap891 you can still use a bessel filter at 40Khz… when using NOS….

Thank you very much for your video. I have a Magnavox FD2040 CD player which has exact transport CDM-1, I have a hard time to put motor assembly back after replace the belt, your video is great help.

thanks for watching and i'm glad it helped you

It is working great now. The original belt is 40 years old. I used 2 mm square belt 128mm length,(64mm when fold in half and measured with caliber). 2mm is beefier than original belt. I love this old CD player's sound-rich and smooth like tube.@@waheex

The piece of plastic at 11.07 looks to me like one of the two little triangles that are underneath the sliding tray.

Good video...what size of screwdrivers are required for removing the drive?...can only find T sizes not H

[@waheex]

Good Video , by the way where can I get the plastic wheel in yellow color that one , mine one is broken ! Thanks

[@waheex]

ohh might be tricky, there's a chap called 'merlinboat' on ebay has a lot of spare for this machine

[@KarlHamilton]

What do you mean by pseudo-16bit? Are they not actually 16bit?

[@waheex]

it's a 14 bit player

[@KarlHamilton]

@@waheex ah ok, cheers!

[@waheex]

16 bit came out shortly afterwards and Philips installed a chip to 'oversample' and make it like 16 bit I believe. Many say it compromises the sound of the player, therefore many removed it and bypass with a mod. Also change the clock speed of the player.@@KarlHamilton
