If it affects all the components, I would suspect the Beomaster. If the CD plays and works its way through the tracks, I would suggest it is OK. The3300 in common with much of this era of systems made by B&O suffer from deteriorating capacitors and variable resistors.
These can be replaced and will return the system to as new. You need either to repair it yourself if experienced or find someone to do it for you if not. Where do you live?
