The center drawing shows a typical implementation:
- a radial line (perpendicular to the manifold/traveler) intersects the record spindle.
- a radial line perpendicular to this line drawn from the record spindle represents the
path that the stylus traces.
The drawings on either side show extreme mountings - with the arm rotated 15 degrees in
either direction.
In all 3 cases, the arm pivot to stylus distance is identical (8.25" for this example).
Note that in both rotated examples, the path traced by the stylus lands too far forward
(ahead of the record spindle) as shown by the dimension line.
The actual dimensions are not important but the principle is. In both rotated
instances, the cartridge can be brought back into alignment by either:
- moving a free-standing arm pod further from the record spindle (alternatively by
restoring the perpendicular alignment), or ...
- in the case of a fixed mounting, by moving the cartridge closer to the arm pivot
