I have a Philips CD-50 CD player that I've used for years as a
reference; it has a couple of different outputs including S/PDIF,
and it's been something that I use to calibrate my ears. Now it's
beginning to have problems - on the first song of a CD it will
dropout and actually skip forward about 1/4 to 1/2 a second, every
5 or so seconds. Usually, it stops that behaviour before the
first song ends.
I opened it up, and looked for anything dirty, broken, or that
looked like it may need lubrication; it was clean as a whistle.
So then I began scanning the net for information, and I can't
find CRAP on it. Does anyone know who I could contact? I've
written Philips, but I haven't heard back from them.

I think the CD-50 has a rotary servo. Put a drop of turbine oil or
sewing machine oil on the top end bottom bearings of the servo.
Do the same for the turntable motor. Clean the lens.

If this does not fix your problems, get the service manual from
Magnavox/NAP and go through the calibration procedure. Looking at
the eye pattern on the scope will tell you a whole lot about the
transport condition.

The optics might need cleaning but you probably won't be able to see the
film of dirt. If the trouble goes away after a good cleaning, that was
what it was.

The simplest way to clean the exposed lens surfaces is to wipe them with
with a cotton-wool bud soaked in (Isopropyl/ IPA) alcohol. The film of
dirt is often greasy (from frying food or cigarette smoke) and will not
respond to water-base cleaners.

Another posibility is lumps of dirt on the spindle chuck throwing the
disc slightly too wobbly for the focussing mechanism to keep up. Give
both the chuck and counter-chuck a good cleaning.
