I kinda doubt it's a Planar 9 with the S tonearm. Probably an older P-3, as the P-9 came standard with the RB-900 arm which has a different mounting scheme from the older Rega arms. If it is a P-3, you could pursue Origin Live updates for the arm (per above), motor/power supply, and acrylic platter. Or you could dump it altogether, and get a newer Rega (P25), Linn, or VPI used. I'd suggest the VPI or Linn for ~1K, then work on updates as finances allow.
