I'm trying to keep using my direct drive turntable, except it has a few isues.
(1). Recently, I can't adjust the speed, so, when at the slowest setting for either 33 or 45, it still runs too fast according to the built in strobe.
(2). When starting up, the strobe light flickers and the table has trouble getting to the right speed (then the strobe light is normal), but see #1.
I'd like to continue using the turntable. Are either of these problems user (I have a moderate degree of elctronics understanding) fixable? |

Probably not. There are most likely servo systems that are going bad.

Try oiling it. use very light sewing machine oil. I also have a sony direct drive and I love it. but i had to oil it a few years ago. |

Any particular spot you recommend or the obvious bearings/friction areas? Will this enable the table to operate at normal speed at both 33 & 45? |

I suspect your turntable is running slow and not fast. If the bars move forward it means it's slow.
The speed is controlled by a variable resister but it can only change the speed slightly. Basic speed is built into the windings of the motor and depends a lot on the 60 cps generated by your local power company. they use 50 cps in Europe and there is a switch in there to convert from one standard to another. If you have it on the wrong setting it will definitely effect the speed.
I will talk more to my brother. He’s a specialist on synchronous motors. |

The turntable runs fast on both 33 and 45. At the slowest adjustment for each pot (33 & 45), the table still runs a bit fast. |

How old is the unit and when did it start to run fast? The circuitry may be the culprit. |
