Reply to Technics 1210 Mk2 Unstable Pitch

Hey DJTT Forum Members,

I am having an issue with my Technics 1210 Mk2. This is my first turntable so excuse my way of explaining this. The problem is that when i am spinning, the deck in TSP is showing a jumping BPM from 128.0-140.0 when the original bpm is 128.0. I checked the dots and they aren't acting steadily like they should be. I need to know how to fix this issue as it wasn't an issue when i bought it. Thanks!
