Is it an auto-reverse deck? If it's single direction, with 2 flywheels, then
one flat belt goes from one flywheel to the motor pulley, the other flat
belt loops around the outer circumference of both flywheels.
If it's an auto-reverse model, then normally one belt loops from the pulley,
over the top of one flywheel, and under the second, coming back around the
top over to the motor pulley.
