I you are looking for a modern version of Audio Technica's AT6002 known as the Autocleanica or similar, this is Tonar's modern quality all metal solution. Well, except for the carbon brush!
Cleans records as you play - reduces record and stylus wear by keeping those grooves dusted while you play - Eliminates static build-up. Will not interfere with tracking force and anti-skate like the brush that attaches directly to your tonearm. This is because it mounts on the left side of your deck and so does not interfere with any tonearm operations.
(from the box)
1. The Tonar nostatic arm may be placed in any convenient position around the turntable. For best performance the base of the unit should be fixed at the distance at which the carbon brush can reach the center of the turntable.
2. Adjust the height of the nostatic arm so that it is parallel to the record surface, then tighten the set screw in the base. Optimum pressure is provided by adjusting the position of the weight on the arm.
3. This cleaner is designed with a conduction path from the tip of the carbon fiber brush to the base. Using the ground wire supplied, plug one end to the base and connect the other end to your systems ground terminal. Use of this ground wire will dissipate static charges and reduce the attraction of airborne dust during playback.
