OK, there is the base of the tonearm tube...(where the tube is screwed to the part that pivots, like a 'base'). There is a spade there that is attached to the pivot base, goes into the tonearm tube and then down the vertical shaft with the tonearm wires, comes out and is screwed to the metal table base with another spade/screw. The other ground goes from the terminal board of the cart shielded leads/RCA shielded leads to the receiver lug ground, via a 20ga solid core wire-that's easy enough to change to another type of wire if deemed too small or wrong type.
