VPI ADS Speed Controller

The ADS design includes two pure analog frequency generators featuring low distortion and noise; a high current Class-A/B amplifier that is transformer-coupled to the turntable output; analog control logic for low noise operation; 33/45 RPM analog speed adjustment controls with center detent positions that are factory calibrated. Created by our previous Director of Electrical Engineering, Michael Bettinger. PLEASE NOTE: If you are upgrading from an SDS to an ADS or have an older table, please leave a note in your order specifying as such and which table.
