So the pre-pro and the amp should both be chassis grounded to a 3rd prong plug? Couldn't that open another possible ground loop or would the Iso-max (hopefully) prevent that? If so, can you point me to a (relatively) simple instruction to safely convert a floating class II to a grounded class I? Answering with no is just fine with me, and thanks again.Both components connected by the link transformer are supposed to be grounded, class I. If they are floating class II instruments, the hum will inevitably increase due to stray capacitances and their non symmetry.
