Back tension is provided by the stationary plastic disk , item 126,
which is held stationary by the slot in lever 87.

Disk 126 differs from disk 83 on the takeup side which has a pin
descending into (spinning) drive wheel 89. That is the origin of
takeup tension.

Both disks engage the felt rings glued onto bottoms of the turntable.

Also, nothing will work properly unless washers 132, 133, 134, and 136
are in place and properly chosen during adjustment.

At one point, Philips sold these washers in kit bags. Different thicknesses
were available.

All the turntable systems are gravity engaged.
