[QUOTE="croak, post: 953530, member: 361"] Many phone gyros are not accurate. Use strobe disc with mains driven light to confirm speed is correctly linked to mains. It may actually be fast or slow if mains Hz isn?t spot on but adjusting for it with independent speed reading (adjusting motor angle) will have you off speed as soon as frequency is corrected on an AC motor. Iow. If strobe lines stand still using light from same mains supply as turntable you are as good as you will be. Phone driven strobe apps are accurate and will verify if the table is mechanically slow or slow because mains frequency is lower than it should be. A good understanding of the workings of motor speed is needed before adjusting to whatever reference. . [/QUOTE]
