RCA 77DX Output Cable

Hey all! I just got a beautiful vintage RCA 77DX. It's in pretty great condition except for the cable. The external tubing is cracked somewhat substantially, especially in one place, and I can see the braided stuff inside. The mic still works perfectly, but I seem to be getting some kind of ground noise when I pick it up by the transformer cup (which for some reason disappears when I then also touch the bottom of the yolk where the stand thread is).
I'm wondering if I might be able to rewire it with a new output cable myself. I would have no idea how to approach it though, and don't want to accidentally damage the mic by mistake.
Also, I don't know what kind of cable to use. I have some Mogami Neglex 2534 Quad Cable.
Is this something I can do, or would I be better off just taking it to ENAK?

Easy replacement. Find a mic cable the same diameter of the old one.
The old cable is soldered inside the mic (mine was).


P.S. I made a mic cable with a small diameter mogami cable and climbing rope. Take the filler strands out of the center of the rope and pull the mogami
in the remaining jacket of the rope. Now it looks like an old style cable.
