I am convinced that you can improve and stabilize a good turntable by the following measurements:
1) ensure you have separate isolation platforms for motor, table and flywheel
2) use a motor and pully which are in good condition and work absolutely stable (in case of older Micro designs maybe check, lubricate, exchange the transformer and/or capacitors)
3) better go for belts than threads. ensure the belts have the same distance and measure the belt tension. should be the same value for both belts
4) the VPI double motor driven by the SDS is one of the most precise and stable motor/steering combinations on the market today
