PUREST AUDIO PT-89-B Turntable Strobe Disc

Allows you to accurately adjust the speed of your turntable to 33-1/3, 45 and 78rpm. Designed for use in artificial light, the disc's pattern will appear to be static when the turntable's speed is correct (because of the 50Hz/60Hz mains frequency). All you need to do it place the disc on your platter, turn on your light and then adjust your turntable's speed control until the pattern on the disc doesn't move.
