Default Re: Reducing Hum Pickup by B&O Turntable

At mains frequency, the skin effect is all but non-existant, so thin wire is fine. Any RF entering the amp should usually be filtered out by design.
The earth connecton from a turntable sometimes causes more problems than it solves; depending on the power and signal arrangements, earth-loop hum can be induced.
