In Reply to: Suspect Jelco specs and geometry posted by hesson11 on January 17, 2010 at 05:04:03:
Jelco have been making tonearms for years, and there is no doubting the accuracy of their technical drawings.
The SA-750D tonearm has an effective length of 229mm, but if you want to align it so that the null radii fall at 66.0mm and 120.9mm then it might be better to mount it so that the centre of the base is at a distance of 211mm from the spindle
Best regards,
BK
