Rabco SL-8

Description

The SL-8 is basically a pivoted tone arm. The pivoted arm is mounted on a carriage which rides in a track, and is servo driven.

As the record revolves, the stylus moves inward causing the arm {cartridge holder} to pivot and thus begin to be non-tangent.

After a fraction of a degree {maximum, 1/6} the cartridge holder trips a switch which in turn operates a motor.

Thru a bead chain the motor pulls the carriage along until the angle again is 90°, thus breaking the switch contact and stopping the motor.

This operation is repeated many times during the record, the frequency of operation depending on the record groove pitch, which varies greatly.
