Yamaha CDX630E service manual

It has been stated that the Yamaha CDX-630E is in fact an OEM version SONY CDP-710E made in France.
The Sony service manual can be found here on this site.

-the Sony 710-E (Europe) has a TDA1541; while the Service manual CDP-710-USA shows a single PCM56 for both channels (very cheap implementation imho).
