Tonearm Geometry Lab

Calculate tonearm alignment geometry for pivoted tonearms, including null points, overhang, offset angle and tracking error.

What this tool does

Calculate pivoted tonearm alignment geometry for null points, overhang, offset angle and tracking-error context.

Inputs:

  • effective tonearm length
  • pivot-to-spindle distance
  • inner and outer groove radii
  • alignment standard or geometry target

Outputs:

  • null point radii
  • overhang
  • offset angle
  • tracking-error profile context
