Today, using a KAB Speedstrobe, I checked a recently-acquired Pioneer PL A-45D turntable and was surprised to find that both speeds are steady but noticeably too fast. The table has no pitch control. It has no evidence of trim pots, either; all I could find was the board pictured below, which I presume is a speed control circuit, since the power mains go directly into it and leads on the other side go directly to the motor. (Note: the slider switch is to select between 120 and 240 volts; it's set to 120.) I have not replaced the belt, but I would have expected belt problems to manifest as wobbly or slow rotation. Any suggestions about how to reset the speed? Oh, I should add that the automatic start/reject/shutoff mechanism seems to be working OK--it isn't interfering with the rotation, as far as I can tell.
