Ah ok, thanks for the info. Yeah so what I tried is one of the computer grounding wristlet straps and clamped the end to the amp ground, and then that seemed to remove the the static and 'hum' every time I touched the tonearm. Guess I was charging the vinyl somehow, and the ground in my turntable must not be internally connected right, else the charge would dissipate through to the amp ground without need for the wrist strap ground, right?
