At a great cost savings, many have had success using the round belt substitution. No modification to your player needed; simply install around the two pulleys just as if it was the gear belt. The torque needed in this system is quite low so there is no need to have a toothed/gear arrangement.
NOTE: The OEM Dual toothed belt 267 224 depicted in the exploded diagram of the service manual as #10 in the below players is no longer available.
