you would have seen that I said the earth pin of the IEC socket should be bolted to bare metal of the case. This "grounds" the case - thus providing shielding to the internals.
IMO signal ground should not be connected to case (which in my scheme of things is mains earth) and preferably, signal ground should be lifted from PS ground (also not connected to the case) by a 10ohm res, so signal and PS grounds do not interfere with each other.
Thanks for the Ralph Morrison reference - I shall see if I can get hold of it.
Regards,
Andy
