I have a CDP397 and its maint. manual. I imagine
that the layout is fairly similar in the 297, and I
am sure that you could get schematics from Sony.
My player is heavily modified, and sounds good
for a cheap design.
thanks for the reply..
actually, the sony service here isn't exactly friendly... which is the dac chip?.. i think 397 - 297 are VERY similar.. think they share the same manual...
