RB-250 tonearm installation Systemdek iix


I am replacing the Profile tonearm on a Systemdek iix with a Rega RB-250. The RB-250 came with RCA connectors, the arm I removed had RCA connectors and a ground wire. Since the RB-250 does not have the external ground wire that the Profile arm had I'm guessing it does not need it. I have googled what I thought I was looking for and did not find any help. The TT has a ground from the chassis/board/lower panel to a stud on the back that has the lead to hook to my pre-amp but the tonearm itself does not have a lead. Any guidance would be greatly appreciated.

IIRC, the RB250 combines the arm ground wire to the left channel ground at the rubber block in the base of the arm.
Bdgregory: I made a few new arm boards and used the rega template to locate the mounting hole in one. Unfortunately when mounting the cartridge the white wire came loose which is actually a good thing because I'm sure it's condition would have caused problems. I now have a cardas kit on order ;-)
The JA Mitchell mod, the counterweight, for that arm, is the best. It puts that arm in another league. You definitely should try it.
