Marantz CD63 & CD67 mods list

The BG's will run at 15v, I have done this myself. However it is very close to the limit and not really advisable. Also, the closer you run a cap to its limit, the shorter its lifespan.

edit: how's the head Simon?

I would like to only change the sregs... I am using 220BG16v on the opamps... is it enough for +-15v ?

Yeh, go with +-15v in that case. The BGs will be happy at that voltage as they're high quality parts.

To change or not to change.... that is the question.

I finally managed to mount my output caps to the cd chassis

Sorry for the poor quality

And please ignore all the wires, they will be tidied up when I get round to installing the additional psu's.

Hi guys!
I'll get for free a lovely setup, seems a bit faulty but looks gorgeous and very promising.
Have any feedback on this stuff, mainly CDP?
It's a Aura CD-50 (seems to be a Philips CD600 clone) and an Aura VA-100.

Hey,

Never heard of them it but it looks pretty and well made.

Looking good now....

My clock setup looks like a power plant..😀

I heard of these amps before.

Aura was the Electronic subdivision of Bowers & Wilkins Loudspeakers (B&W UK) before being discontinued in 1997, they were located in the same town as B&W (Worthing-UK).

Now it has been bought by a Japanese guy who keeps doing good stuff:

Super Hyper CD53

Here is an overview of the setup.....

The sound is really outstanding..... This player sings

I just built a +15 sreg.... now the -15v is on the bench.

So anyone looking for a parts player? I have my modded player and all modded parts go with it as well as removed parts and original remote. Transport works fine. Unit was working great now it plays for a bit and then the audio slowly fades. If I turn it off and on, it does the same thing but takes less time ... I'm assuming heat related.

I have too much audio equipment laying around to bother fixing it, so have at it!

Mods here: http://www.craigtone.com/audio/CD63/

Make me an offer!

Ray,
I'm now ready to get going with your discrete output stage as my 8260 is the same as your 8400.
I have a question about the power connection. Your design shows +-15v followed by a 12v regulator. Where are you getting 15v? Power on the board is 12v already. Why the extra caps and regulator?

Hi Steve,

I used on-board shunt regulators on the discrete output PCB because the regs are closest to the circuit that way. It's a single-ended design, so it's quite sensitive to PSU noise. I used the players' analog supply as pre-regulators to power the PCB. The output voltage was modified to around +/- 16V by changing R853 and 855 to 4k7.

I'm curious what you think of it, can you let me know how it sounds?

Regards,

Ray

Looking good and excellent news on your improved audio 😉

Steve,
I haven't even ordered parts yet, but will soon do so. I'll be sure to let you know how it all goes when it gets going.

LM4562 sounds better with 15V? No problem in changing 12V Raygulators for Brent's Regs 15V?

Hello Ray,
I expect to modify my CD65II with the help of what you did with this player shown in your usefull website.
Just a few questions:
-which opamp do you think gives best results for money spent?
-Do you have a pcb layout document that clearly points each component (front and back)? Many of them are not printed on the PCB, resulting in a boring schematic searching task.
Thanks a lot for all that very good stuff over here!!
Regards,
Eric.

 

[Malefoda]

If you don't mind me to reply for what I've tested the LM4562 with Black Gates caps does it the best to my ears.

 

[6h5c]

Hi Eric,

I scanned the manual myself, cause I have it in old-fashioned paper. I can scan the PCB for you, but you have to be patient, as I don't have much time at the moment. Just PM me as a reminder and i'll send you a new PDF.

My favorite opamp-combo still are the AD8610 and AD8510 on a BD adapter 🙂

Ray

 

[ggn]

Thanks!
I guess I will have to perform some tests anyway, regardless of what it costs
I will upgrade the player to Ray's specs (if he's able to help me 😀 ), except for the opamps at first. Then I'll try different amps.
Regards,
Eric.

Ok, thanks a lot Ray.
