Hello Danny,
Welcome to the forum.
Are you saying that the tone arm and the cartridge is missing the record, i.e. falling short of the record and dropping down the side of the turntable.
If this is the case then your tone arm adjustment are way off and I would look for one of the two pins that are on the rear of the tone arm that follow the tone arm cam has broken off or the tone arm cam is loose.
Thee are a number of adjustments that work hand in hand so you have to start going all through the adjustments starting at the first and working your way through them.
However you do need to check the transfer motor and the transfer linkage for any mechanical faults before checking the adjustments.
Regards
Alan
