| The SOTA Stroboscope Disk allows you to accurately set your turntable speed if your turntable features fine speed control or to inform you of speed problems. This stroboscope can be used to test for both 33-1/3 and 45 rpm speeds at both 50 and 60 cycles AC. This four-inch diameter cardboard stroboscope disk is extremely easy to use. Simply place it over the spindle of your turntable and turn your turntable on. The outer band is used for tuning 33-1/3 speed and the band second on the inside tunes the 45 rpm speed. You must use an AC powered light or lamp to illuminate the stroboscope. Originally made for SOTA turntables, this fine Stroboscope comes complete with easy to understand instructions. You can spend up to $100 for another stroboscope and not do much better. |
