SOTA Star/Electronic Flywheel?
I have the Star with the power supply/vacuum box connected to the small controller, then to the table. have an opportunity to pick up a used 'Electronic Flywheel'. My question: Where in the sequence does the flywheel connect? reason,for asking my vacuum/power supply box has been 'hard-wired'.
