New and reviewed in the December 1956 issue of Popular Mechanics, the Mercury Scientific Products Corp. manufactured DIS-CHARGER is somewhat of a mystery in 2015. We know it helps to keep records dust and static free, but we don’t know how! (Quick Google search) Ah-ha! We do now! From the mouths of babes (or mechanic nerds from 1956), here is, verbatim, how the Mercury Scientific Products Corp. DIS-CHARGER flawlessly functions:
Records will sound better and last longer when tiny Dis-Charger, Fig. A, is clipped to record-player tone arm. Unit draws off static charge as record is played, releasing injurious and noise-producing dust clinging to record grooves. – Popular Mechanics, December, 1956 (page 157)
