On my 42-1010 console, there is a small black cast metal box mounted to the cabinet next the the chassis. The harness to the beam of light pickup connects to this box with a 4-pin plug, and there is an RCA jack on the box as well. What purpose does this box serve and what's inside?

Which would explain why I had no audio from the phono until I reconnected it. Audio levels came up a bit with the contacks cleaned, but I'm betting that the cell is pretty much shot as I just can't get much volume without turning the volume knob up at least 3/4 of the way. Not a big thing until I forget and switch to radio and blast the furniture across the room!

Once I get the dial restrung and get the chassis back in the cabinet, I'll tackle replacing the cell.
