Technic SL5200 turntable speed is to fast on 33/45

1. Some of these turntables were designed to work on multiple voltages. If yours has a voltage adjustment make sure it's set for 110 or 120 V (North American) or whatever your power line voltage is. 2. Does it have a variable speed control with markings around the platter that tell you when it's on speed? if so, make sure you're reading the right scale when you adjust speed. Some Technics turntables have scales for both 50 Hz and 60 Hz (North American) line frequency, with two rows of dots for each, and if you're looking at the wrong scale when you adjust the knobs you'll get the wrong speed. 3. If neither of these solves the problem, you'll have to take it in for service.
