So I got a AT-PL50 for my birthday and it’s great for my first turntable. My stepdad has a stereo setup downstairs so sometimes i’ll bring it down there instead of using my speaker in my room. I’ve had this issue before a few days ago, but when I move the turntable back upstairs, the rpm messes up. The first time it happened it fixed itself after I just played it and then stopped it, but this time that didn’t work. It seems as if the 33 RPM setting is playing at 45, and the 45 setting is playing way faster (maybe 78, I can’t tell). I am aware that there are adjustment holes at the bottom of the turntable but I’m wondering if there’s any other potential fix since it fixed itself before.
