Background: I currently own a Pioneer PL-570 turntable, which based on its appearance is probably a 1980s/early 1980s model. I bought the turntable used a few years back to play my collection of thrift store records that had been sitting around in my closet and it continues to do a fine job...
Moving on. To connect the source to a receiver/phono preamp, the PL-570 has a built-in cable on back (about 3 ft) with standard RCA connectors on the other end (in other words, the cable is not detachable from the turntable). And, there are no other possible outputs or connectors for making a connection to a receiver/amp. Fine. Not a problem.
The Question: What I'm puzzled about is an extra wire coming out from between the right/left channel RCA cables (the cables are joined until near the end) that I haven't been able to figure out the purpose for. This mystery wire is small gauged and terminates in a single horse-shoe shaped prong/connector. Presently, the wire is just dangling free and the turntable seems to work just fine, but I'm curious about the wire's actual purpose. What the heck is this thing? Any ideas?
EDIT: Ok, I figured out the mystery wire is the ground wire, but the back of my receiver (which has a built-in phono preamp) doesn't have a spot labeled for the ground wire. So, now what?
