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.

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:smash:

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.

My clock setup looks like a power plant..:D

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.

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:

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!

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

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.

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.
