Just to confirm, this Turntable project is to control the movement of the turntable, correct? You'd still need an AR-1 to deal with the polarity, right?
If your turntable is manually operated, you just need the AR-1, correct?
I ask, as I'm in the midst of installing my Peco turntable (manually operated - for now), and I have an AR-1 for the polarity, but no AM-1S.
