Re: Grounding issues

A turntable is a special case, the signal is not necessarily grounded to anything on the turntable, and chassis or signal grounding the tonearm tube and/or plinth base (or the top metal plate) is often helpful in intercepting hum.

It might help to think of it this way: on a turntable, you are extending the system ground out TO the 'table, in order to provide shielding for the cartridge signal. A turntable is seldom a true SOURCE of a ground, so the old rule-of-thumb about using the source as the ground reference does not hold true.
