Additional Information

  • S2-R Aluminium shell detachable and interchangeable without disturbing cartridge or wiring.
  • Double draw-in pin bayonet fitting design ensures a rigid junction with the tone-arm.
  • Stainless steel ground horizontal spindle carried in substantial yoke in lOmm diameter precision ball race bearings.
  • Stainless steel ground vertical spindle with integral 16mm diameter flange to couple the spindle with the yoke.
  • The 23mm diameter steel pillar is heat treated, ground, internally honed and carries two 17mm diameter precision ball race bearings widely spaced to resist tilt.
  • Internal wiring is Silver Litz.
  • Internal constrained layer damps minute residual vibrations making the tone-arm acoustically inert.
  • Unique headshell to tone-arm coupling readily allows cartridge azimuth adjustment.
  • The Anti-Skate control operates through an Anti-Skate weight and filament and is adjustable for up to 5g of cartridge vertical tracking force (VTF).
  • The lowering/raising control gives a smooth positive action and allows for the lifting height of the cartridge above the record to be adjusted.
  • Tungsten-alloy balance weight inserts allow for maximum centre of gravity shift to balance a greater range of cartridges. Up to 38g in S2-R headshell and direct plug-in heads up to 46g.
  • Precise vertical tracking force up to 5g is applied in 0.5 increments via the rider weight and graduated wayrod.
  • Thumbwheel cartridge vertical tracking angle (VTA), height adjustment.
  • Bedplate affords +/- 12.0mm movement to facilitate horizontal tracking angle (HTA) adjustment.
