Ground the player chassis or the RCA shrouds and you're done? Or am I missing someting?

I just feel that by persuing an ad-hoc fix such as a 'special' ground (spring?) I am possibly sidestepping the real cause of the problem. Given the number of Empeg's installed to-date, I can't help but think that _I_ must surely have something wrong in my install otherwise:
a. It would have cropped up before (E.g. appeared in the FAQ)
b. The need for a special earth in the sled would be a design flaw (I don't buy that especially given the no.of previous installs).

One thing you didn't say: Whether you own a Mk1 or a Mk2 player
It's a MK2

Edit. Reworded item b.
