These amps do essentially have a star grounding scheme. Thats why the RCA jack ground must be returned to the star ground instead of being arbitrarily grounded to some point on the chassis. Often the chassis safety ground is NOT connected to the star ground point if this induces hum because of its interaction with the power transformer. But that sacrifices the safety effects, of course. So a solution is to connect the safety ground to another point on the chassis far from the star ground point.Long story short.. no ground loop problems or coupled 60hz hum and a safety ground in place. No worries.
