The turn table is going round but its playing the record to fast the speed seems wrong

I believe this is a belt driven turntable. With the power off, carefully remove the rubber mat. Turn the platter by had until you see the motor pulley through the open holes. If you carefully look at the belt, and it has slipped upwards to the top of the pulley, and not within the guides, that will cause it to spin very fast. Move the belt down between the guides on the pulley. Rotate the platter by hand, to be sure that the belt stays withing the guides.If you need more assistance, or would like to inquire about a repair, please visit my website at audioserviceclinic.com, and contact me there. Thank you.

Hello!
are you sure, that your speed selector is on 33.3rpm, not 45?
assume, it's in correct speed settings. do you know, that across the ocean power grid AC frequency is 50hz, in US it's 60hz. Means: ac motor will spin faster, than it should. If you bought this unit abroad, that's where is your problem at. some expensive units have 50/60hz pulleys switch, some not. Especially, if it's DC or direct drive motor. Check your owner's manual for specifications. May be you find an answer. If not, there is a problem with motor's regulator, which is built in(DC motor). Turntable is a belt driven. If you won't find 50/60hz adjustments, take it to repair shop.
Good luck,
Alex.
