hi i have a vintage fisher studio select turntable
i just got this off cl but i herd it work and was stupid enough no to pay attention when the guy unhooked it and know im lost.

what has me confused is that there is what seems to be a ground coming off the negative RCA cable and there is also a laminated pair of wires that has a plastic cap and a screw hole in the top and the two wires are soddered together i have no idea what these are for

any help would be appriciated

thanks
