I own an Audio-Technica AT-LP60 turntable and a decent record collection. I’ve noticed that just about every record I play on the turntable wobbles at least a little bit. Is this normal? I don’t notice anything audibly while playing records but will the wobble damage my records or the needle? I’ve tried taking the slip mat off to see if the platter is the problem but it’s hard to tell (without anything on the platter) if it is in fact the platter itself that’s wobbling.
