The correct anti-skating force necessary for a particular
cartridge can be determined by means of a test record
which incorporates a tracking test, for instance CBS
no. STR. 111. Whilst playing this part of the record,
at first without anti-skating force, reduce the stylus
force until distortion becomes audible. Normally it is
first audible in the right channel and upon a further
reduction of the stylus force, in the left channel. Adjust
the anti-skating devi
