I've noticed on many of their mic input transformers Jensen and Cinemag have separate wires for the Faraday shield between primary and secondary windings, and a wire for the case/can. Jensen and Cinemag say to tie the Faraday shield to signal ground and the can wire to chassis ground. What's the point of this? Pin 1 adherence? What are the advantages? Inquiring minds want to know.
I also note that the ancients usually tied the Faraday shield to chassis ground (RCA using UTC transformers, for example), and their stuff sounded pretty good and measured well. If the transformer only has a wire for Faraday shield (no can wire) is it best to tie that to signal ground or chassis ground? The can usually mounts with screws or a clamp to the metal chassis, so it manages to get grounded without a wire.
Thank you in advance for wisdom.
