You can do a simple trick:
use tape to attach any wire to the base of tonearm and connect it to the ground pin of your preamp.
If problem disappears, than ground wire is relatively easy to replace compared to the signal wires. The ground wire usually connects outside of the armtube, than goes through the hole and than out to preamp. The only trick is not to loose proper horizontal bearing tension if it needs to be removed.
If you want to communicate further, you can e-mail me.
I repair various turntables daily and restore them to original fully operational condition.
