Schematics or service manual for philips cd960

[kipperville]

Winter's long nights are coming in and its time to clean up the hifi.
Does anyone have schematics or service manuals for cd960 player, I'm
going to replace the caps for starters. Also can someone recommend a
line out volume pot set up to take line out signal directly to power amp
(Kenwood/Trio Basic m1) as my Nad 3020B pre amp section seems to output
a quiet hum through the speakers.

My current set up consists of Philips CD 960 player, NAD 3020B,
Kenwood/Trio Basic M1 power amp and Castle Acoustics Conway mkII
speakers. Other equipment I have are Celestion DL6 spearkers and a
Kenwood KA 4010 integrated amp (if anyone has schematics/service manual
for this would be great)
