I am a proud owner of one. I bought it in 1998 and its still going strong. I haven't modded it but I put some blu-tac on the horizontal cross brace and in the holes on top of the transport, to reduce vibration. T

he only complaint I have are the weak RCA output jacks. Interconnects can be hard to unplug and juggling can damage the solderings of the RCA output jacks. I have had to open the machine and re-solder the jacks.

Does anyone know of better RCA output jacks for this kind of player?

On my first modded unit I changed the 2 stock RCA sockets with something like this:

You just solder the RCA sockets out from the PC board and use short cables to connect the new RCA sockets.  It is relatively simple.  The design of CD63 is so good that you can easily strip down all the parts and not like those modern day designs that taking apart a unit is almost impossible. 

On my 2nd unit I will use high grade audiophile RCA sockets with very high purity audiophile copper cables for connections.

 I think I'll give the insides a good clean first, can you recommend something I can use to clean the pcd and capacitors....is it ok to use contact cleaner and compressed air?

Thank you, it helped. I opened the case, used a blower on the pcb and then sprayed the whole pcb with contact cleaner and then sprayed the front panel with contact cleaner. It looks new! Not a dust bunny in sight! Unfortunately, I do have some scratches on the cd player's display, any idea what I can do?

Yes. It is an old watch makers trick to polish out scratches and I've used it in the past on Swatches which use a plastic crystal.

 Takes a bit of elbow grease and has a habit of getting into nooks and crannies so I'd advise to either take the display cover out if you can or tape off the edges.

Ha drummerman you really have a lot of DIY knowledge :clap:  This is an old trick and I used to apply the same stuff to bring my watch shines again.

RE: Marantz CD 63 MK-2 KI Signature

Thanks for that.

Do you use any special kind of cables to connect the RCA socket, or just ordinary jumper cables?

Recently the left channel of the player has started to distort and crackle the sound a little bit. I also notice low clicking noise on the left channel when I change tracks on the CD. This is not the case when I use the headphone output. I suspect the muting transistors in the analog output are starting to fail. Has anybody removed these muting transistors, and does it improve the sound?

RE:

I don't think it would make the player sound better, I thought when muting transistors were off then basically they're out of circuit. Hey try it, what's the worst that can happen Smile

RE: Marantz CD 63 MK-2 KI Signature

Muting trans. eliminate interference noise when cd in not playing. With them removed there should be a popping noise when you power up/power down the cd player. Workaround: Power up cd player before amp - power down amp before cd player.

Kudos to you Drummerman, worked wonders on my Marantz....the change is quite unbelievable. I also used brasso on my watches and they look great too. I did use contact cleaner after brasso and it seems to add some shine to it.

RE: Marantz CD 63 MK-2 KI Signature

Removed the 4 muting transistors and I am quite impressed with the result. The sound opened up and is clearer. Minor drawback is low "click" sound when I turn on/turn off the player. Its not loud so no big deal.

Brasso works well but can leave it's own fine scratches. If you want to refine the finish afterwards, something like Meguiar's PlastX (available online or sometimes from Halfords) will refine it Smile
