Has the cable been soldered on at the factory? If yes I WOULDN'T mess with it if I were you.
In many cases grounding only adds unwanted hum and noise. I had to use cheaters (VERY dangerous) to lift the ground in my old studio every time I was using tube amps and some of my older analog synths. If the cable has been soldered on by the original owner, then do yourself a BIG favor and take it to the shop.

Internal circuitry can be pretty $$$ to fix. It cost me about $350.00 to replace the mother board on the mentioned 01/W...
Had I waited a bit longer to fix it it would've eventually fried completely. WIth sparks, smoke and the whole show...
Try not to wait for to long.
