"...a shockingly big deal — the ADS is killer."   - Scot Hull

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 detente positions that are factory calibrated.  Created by our Director of Electrical Engineering, Michael Bettinger.
