I found an old record player in a dump, and I'm trying to fix it up, though I only have a passing knowledge of electronics and audio. There are two shielded cables coming out of the internal pre-amp, with the shielding of one of the cables also connected to a pin on the pre-amp, but the plugs have been cut off the ends of these cables. It also has no ground cable.
How should I connect RCA plugs on to these cables: what connects to the ring, and what to the tip?
Do I need a ground cable? What do I connect it to?
