Jumping CD player

[cjnuk]

Hi all, apologies if this isn't the right forum but does anyone have any bright ideas about stopping a cd player skipping during playback (that is, the music jumps forward, not the player itself doing little jumps around my room!)

It's an Arcam CD23 FMJ which seems to use a Sony transport. No amount of lens cleaning etc helps and it makes having all my other gear pretty pointless if this happens. It seems to be worse during the earlier tracks of the disc, and even does it on brand new, totally untouched disks too. The player is on squishy isolating feet and does it with no external vibrations anywhere near it.

By the way I have a WAD PSU/Pre2 into KEL80s so my credentials aren't too bad!

Any suggestions gratefully received (including any ideas on what the transport mechanism is and if they are available to replace). Thanks!
