iamwhoiam, All

Sorry if this sound a dummy question. I was aspired and try to do some mod on my newly bought CD5001. My 1at attempt will be to replace the 6 bipolor coupling to ROE electrolyte non-polar with 0.1 bicap. It should be the simplest upgrade and have audible difference I guess.

However, I got stuck at the beginning.

Could you advise how to unlock the ribbon cable between the mainboard and the CD drive (also, those two ones between the m/b to the control panel PCB? Thanks.

Finally, I've done it.

just be careful with the ribbon cables ......

the push in one needs to be lifted square and fitted the same way.

the others with the clamp are easy

Due to the overwhelming response from people requesting the service manual, I have re-uploaded it here:

http://www.ukns.org/uploads/diy/cd5400.zip (compressed with Winrar in zip format). Might not work in XP, but will definitely work in the latest version of winrar.

RE: 4real
Thanks for the input, I guess I'll take a look and swap those capacitors for the DAC output caps and see what it feels like. Did you find the new opamp improved much of the detail?

edit: Sorry for lack of replies, I haven't used the CD5400 much since. It's now rigged up to my parent's AV system as a better-than-dvd-player-cd-player. Hmmph lol.

RE: 4real
Just to reiterate for those who want to attempt this mod. In my original posts I replaced C210/C310 caps. This is not needed as 4Real has found out. So just short them out with a jumper. DC actually comes from the DAC. Which are C201/C202 (left channel), and C301/C302 (right channel). So replace them with audio-grade polyprops

RE: Muting capacitor mods
Remove Q404/Q405/Q406/Q407
