Case in point - I owned a house where all the ground wires were properly connected in the upstairs apartment the ground from the breaker box ran to the plumbing stack - and the stack switched from metal to pvc half way down. One such method is a grounding clip that clamps the ground wire. You can find them in 10 2 4 8 10 12 14 and 16 gauge. Usually itll be attached to the underside of the turntables metal chassis.
