Post Subject: Again With the Star GroundingPosted by Paul S on: 11/28/2020
Again, there is no need, even for "safety", to have a separate ground wire if everything is star grounded. Since the neutral and the safety ground connect at the service bus, running the "safety ground" back to that bus for your phono stage apparently makes a classic ground loop, at least as far as your phono stage is concerned. Double Hz of service cps is "normal" noise.
