On lead in grooves I get a distinct sound from my TT and wondering what it could be and if I could fix it. It sounds like a whooshing, rumble sound that is then masked by the sound of the music. The motor had a noticeable scrape sound coming from it at one point so I took it apart, cleaned it and added a touch of oil. Scrape sound seems to have gone but I want to make sure this rumble is either from the motor and can be fixed or is within an acceptable level. The fact I hear it makes me think it’s not, however I cannot guarantee it’s the motor. TT is on a heavy stand and on a concrete floor so likely not related to feedback.
