In Reply to: S shape Tonearm vs straight tone arm posted by carstensf on April 24, 2007 at 13:23:52:
Hi,Regarding alignment of a cartridge, the tracking error is the same for an s-shaped tonearm as it is for a straight tonearm with an offset headshell (not a straight tonearm like those popular on Vestax DJ turntables which do not have an offset headshell). Tracking error is determined by tonearm effective length, the mounting distance and the offset angle. The shape of the the tonearm between the stylus and the pivot has no effect on tracking error.
From a design point-of-view, the differences between a straight tonearm and an s-shaped are subtle. An s-shaped tonearm can have vertical bearings that are aligned with the cartridge even when the vertical pivot axis is perpendicular to the tonearm tube, whereas this is not possible for a straight tonearm.
For a straight tonearm to have vertical bearings that are aligned with the cartridge, the vertical pivot axis must be offset by an angle of about 20 degrees from perpendicular.
Best regards,
BK
