The scratching noise is quite unpleasant for those who pass the sound of vinyl records to other media and the record is scratched. With this circuit, obtained from a 1981 publication, this noise can be filtered easily. The circuit can be assembled with a BC549 and the operational one can be replaced by equivalents. As consumption is very low, a battery can be used for power. The circuit is interspersed between the turntable arm and the input of the playback or recovery media.
