Jack,
Never thought of the extra coil ground being a problem. I think I'll ohm out the ground lead from the box and see if it's truly at ground. Hasn't been a problem (yet). Come to think of it, at worst wouldn't the output of the CD be unreferenced to ground ... so grounding one leg wouldn't hurt a thing.

So, ok, WHY would you NOT want to ground one leg out of the CD box?
