The polarity thing happens a lot and I'm not sure if there's a right or wrong as my Stam 87 , Beesneez Arabella and Gefell CMV 563 are all reverse polarity to what conventionally is considered correct . Who knows? Cheers, Ross
Well some people insist on sticking with the old Fashioned protocols.
Pin 3 hot was standard in the US broadcast and recording industries right up until the AES endorsed Pin 2, probably to resolve the conflict between US and Euro standards in the 1970s. There was a fair amount of resistance in the US audio world. I believe there's still one guy in the SF area whose license plate still reads "PIN3HOT"
