Hi all - need some expertise please…Asking on behalf of a mate.
He’s got an SL-1210mk2 with Ortofon 2M Bronze connected to an Emotiva PT-100 pre-amp which has a built-in MM/MC phono stage. He’s connected the ground wire to the grounding post on the PT-100, but has noted that the PT-100 itself only has a fig-8 power inlet and therefore does not appear to be earthed. How can the turntable be earthed if the equipment it’s connected to isn’t earthed? Does the ground wire need to be connected to an independent earth?
I obviously would have thought a reputable manufacturer like Emotiva would have this covered. Thing is he heard a couple of sharp ‘bangs’ from the direction of his gear a few days ago (not in use at the time), and can’t figure out what caused them. Following these ‘bangs’ he subsequently noticed that the cantilever on his cartridge was heavily skewed to one side. Neither of us could figure out how the two could be connected, although it seems like a remarkable coincidence. He’s adamant nothing else could have happened to it since he last used it. The turntable earthing is the only thing we thought didn’t seem quite right.
Thanks for any advice!
