put finger to keyboard and
composed:

This very old but very nice cd-player has got a hiss in one of the
channels.

I have a copy of the service manual. Would you like me to scan the
decoder circuit for you? The relevant ICs appear to be 6519/6520
(TDA1540 DAC), 6523/6525 (NE5532N op-amp), and 6517 (SAA7030).

IIRC, the PCBs in these Philips/Marantz CD players had problems with
thru-hole interconnects between the top and bottom ground planes.
