I don`t think you can hear any vibration in your Scout, you may be able to feel it. If you are concerned about vibration I urge you to buy a Stethoscope from one of the popular drug stores, should be under $20. You won`t believe all the vibration you will find. Until your motor is sitting on it`s own isolated plinth, you will have excessive vibration creeping into your table and arm, realy messing up the signal.
