Strips of metal with u-shaped slots go over the electrical Get hold of studs on the rectifier assembly. To isolate the diodes bend these strips away to each side plenty of to isolate them from each other.

This removes the sound Because the tunes signal about the RCA cables is AC voltage as well as sounds is DC voltage which are unable to pass through a transformer.
