Hi All - I just snapped up an Arcam Alpha 6 cd player for $40, it was sold as faulty as it had suddenly stopped detecting when a disk is inserted. Its in good physical condition plus it comes with orginal packaging, manual and remote which also suggests its been well looked after. My question is - does anyone know how these players detect the presence of a disk? According to the seller it just stopped detecting CDs, rather than getting flakey over time. Am hoping its an easy fix when it arrives later this week. Any suggestions where I should start?
