Is your motor on the small metal notch vibrating and the motor is pulsing but not turning? It is highly likely it is a transformer fault and you'll need a new one. It has happened to be twice now. It has nothing to do with lubricating any parts or not having the turntable cord incorrectly attached; ProJect produced some power supplies that have incorrect wattage and it will not power the motor enough. I had my replacement today and it works perfectly!
