Philips CD960 transport belts?
Source: http://sci.techarchive.net/Archive/sci.electronics.repair/200807/msg00867.html
From: Paul <paul.homchick@xxxxxxxxx> Date: Wed, 30 Jul 2008 17:40:(PDT) I have a Philips CD960 CD player which has been in storage for a while (okay, eight years). The rubber belts in the transport have hardened and stretched and need to be replaced. Does anyone know of a source for these parts? Philips service here in the U.S. doesn't seem to even know that such a piece of equipment ever existed. Any help appreciated!.
