Marantz CD63 & CD67 mods list

[6h5c]

Yeah, I know... I was/am busy building ezDACs and Crescendo amps

I didn't have a CD63, so that didn't help either. With a nice KI in the house, some more possibilities are available. It's nice to fiddle around with the players again!

I wonder how it will sound when I hook it up to my new DAC...

Thats what is in my CD850MKII which i think is almost identical. I had that player from new until last year! Its very laid back compared to a 63. The only mods I had in my 850 was the Trichord 4, op amps and caps. I have to say, I prefer the CD50 (TDA1541) series of player with these minor mods. I never modded mine enough to properly compare to the 63 or the 1541.

Also, they are used before tda1547 in cd17's (well at least in 2 of the 3 models). Also before a pair on 1547's in the Teac VRDS10

Mine was very relaxed but lacked detail (albeit I didn't realise at the time!). I think you'd probably be quite impressed. I had no nice regs or caps (other than on the op amps)

Also this dac was used in the pink triangle dacapo which is (so i beleive) an awesome sounding DAC! Another thread maybe Simon!?!?

That looks very nice Ray!

Simon see here for some SAA7350 stuff!

Makes me feel like starting on the player again!

Ray, that's a beast!! Tell us how it sounds when it's finished

Ian, I've seen that thread and started this one:

Marantz CD42 repair and mods

The lack of replies suggest it's not a common player, although that didn't stop the CD650 thread going berserk

I have a CD72mkII, with this chip followed by a TDA1547. I think it sounds very nice already, and it's not fully modded yet. But the sound has a kind of calmness with the right opamps behind it.

The "beast" is a rebuild of my first ezDAC, only this time with discrete regs on the supplies and relais PCB with three digital inputs. I think it's going to be the heart of my system soon

I tested your C2 with the servo clocked this weekend. It's clearly an improvement! (but I guess you already knew that )

The soundstage has more depth, cymbals are less grainy and the overall impression is that the player sounds more "in control". It's like the player has pitch control and it's playing at -2%, very relaxed. Peace and quiet has come to the music. Absolutely a recommended mod.

Hey, this is all new to me! This is my first heavily-modded CD63! I'm going to insert the regs for the +/-10V soon...

Regards,

Ray

Hi Ray

Not much room left no LOL

The servo clocking mod is fantastic, it removes alot of problems from the 63. Have you added good regs to the servo yet? This improves further.

That looks very nice Ray, relay muting too. Now for the boring bit - wiring it all up LOL

The tweaks I did yesterday have improved the audio a small amount, the whole picture is clearer yet smoother with more detail to the treble. This is one I am really suprised about considering what's already been done to the player.

Loads to do on the TDA1547 chip too!

With that chip you can bypass the built in op amp output stage and replace with a DOS very easily! Also lots of 5v feeds to sort!
