Hum in a phono cartridge?


Hey everyone, just kind of thinking out loud. Phonograph cartridges are balanced, and should be isolated from the rest of the turntable, electrically, right?

So then here do any ground loop problems come from?

A phono cartridge ground loop could come into existence if the cartridge body is not electrically isolated from the headshell / tonearm assembly, _AND_ one of the negative polarity right or left cartridge terminals is bonded to the cartridge body.
