Marantz CD63 & CD67 mods list - Page 1356

Hoping this will be useful:

I found at least three ground loop in the schematic of this cdplayer (see images), and also ground traces that intercross (is this the right word?).

Anyway, I'm going to rebuild all the power section and conseguently all the ground design.

Could anyone suggest me a good and cheap diy clock for this player????

I think the Kwack clock is intresting, but I don't have an oscilloscope, so I can't build the version 7.

Can you help me?

WONDERFUL THREAD!!!!

Nice one, people can now see the gnd problems within the 63. Its the reason a few of us have cut tracks and run individual gnd wires to a star gns point.

No problem at all.

I am using kiwames in the DOS.... I like them better than Takman carbon.

You might want to try the LT1028ACN8 in the after-DAC-filter stage, as it's much more transparent than the OPA627 for instance. It would make for a wonderful intermediate stage, before the HDAM.

Is that before the HDAM is bypassed

Highly Discarded Annoying Module?

Ok Ricardo, I've used Holco in mine and may give a try to Kiwame once.

Didn't follow this thread since I don't have these CDPs... I only read one or two posts (and looked @ the pics above)

But it's equally worth trying the LT1028ACN8, HDAM or not...
