I didn't bother taking photos of bottom pan rust, marks and oxidation of the platter, peeling vinyl-veneer, lid covered with rash and scratches... My focus was on the insides and the VDS (vacuum system) that wasn't doing what it's supposed to.
VDS platter compressing mechanism proved to be incorrectly assembled at some point and poor rubber belt that was trying to overcome that stretched and hardened. Replaced the belt, rearranged the cogs of the "Archimedes" pulley system. Sorted.
Rusty actuator arms were not snapping back into "released" position. They were coated with so much graphite grease underneath that release springs couldn't overcome the grease viscosity. Cleaned, de-oxed, reassembled, sorted.
Motor rotor was rubbing on the PCB underneath. 1) Missing thrust pad and 2) feedback circuit magnetic ring glue came undone. Sorted.
Platter was almost rubbing on the top ALu surface. Found that the internal suspension decoupling cups almost reversed their shape from suspended weight and age. Treated with Aerospace 303 to recover some elasticity and inserted washers to increase the height. Sorted.
