McIntosh MA6500 turntable hum

I appear to have broken the ground connection on the phono input jacks, causing bad hum. Touching a wire from the jack ground side to case ground quiets the hum. Opening the case I find that the input jack is part of a cluster, and the ground connection is not easily acccessible. Is there anyone with advice to remedy this problem.

Can you run a new wire? It may be easier than trying to find the break.
