I'm using a spare TX wich gives 15.6V DC.
Maybe a pre-reg as a 7812 will be nice here or my LT1086 (wich can benefit of a huge heatsink) at an ideal voltage (9V?)? No side effect?
Also it's now used for 7805 at DAC's analog and Decoder's analog, have no idea if use it only for DAC or DAC+Decoder+Clock Ref...
Remember I use SMD regs ( http://img142.imageshack.us/img142/9682/dsc00023aoj.jpg ) wich have less heat tranfert surface and after havin my finger at the Decoder's analog 7805 it's hot, no way to burn me but more than warm.
Thanks felows,
Matthieu

For any make or model cd player you should start by improvong the main psu capacitors and diodes (pre reg). Then look at changing the post reg caps with something much better. After this move onto the decoupling caps local to dac, decoder and audio output. Also swap any opamps that maybe there.

That more or less sums it up 
Don't forget to upgrade the analog filter, if there is any. The DAC in the CD5000 has an integrated opamp (not so good...) so it may be possible you have no extra opamps in there. It's a decent player, just don't expect the world from it ;-).

@ Brent: C2 testing will commence tomorrow...

Nice cool ideas about regulating servo´s 10v..... What should we expect from such a mod ? Better definition ?
I did power the servos with a dedicated psu and some sregs on the 5v lines but I am puzled about this 10v stuff.... what should be the benefits ?
What is the function of the 10v lines inside the servos ?
Looking forward for your comments Matthieu !

Hi guys,
Glenn that is nice as I'll have more room there to fit my regs.
Ricardo the idea here was given by Glenn who will confirm it does great for bass control & timing. Brent added the fact that at 9V it works like a charm. Mine should do 9.7V according to resistors...
About the sample Ti is upset and my last order had comment like "man it cost us money what exactly your company build?"... I must slow down...

I think they're checking out the people who've ordered samples. They want to come round to my house and help me build my dac! Which is nice of them, but I've had to put it on hold due to a lack of funds
