Please help! Slow turntable!

I recently purchased my first record player from a second hand market for a bargain of $100 aud. it's a silver (brand not colour) stereo system 100 hifi and I have noticed that all my records run slightly too slow. I really need help as I'm fairly new to record players.
Thanks in advance

If this record player is of the vintage era, it's most likely in need of an overhaul and restoration in order to perform properly.
Best to look up a local tech in your part of the world and have it serviced.
