Al, thanks for your concise explanation of what may be occurring through pin #1. This is very enlightening to me and, I presume, to others. There is so much opinion batted around on DIY cable threads that only seems to confuse rather than clarify. I would have continued to regard pin #1 as something of a nominal requirement, a connection made for the sake of continuity, for safety, a default run that allows me to ignore all the shielding opinions, ad nauseum. More so, congratulations--your paragraph is golden for me, the novice, and should be regarded as a breakthrough in relieving confusion for many.
Cheers,
Joe
