The Linn arms are normally 211mm pivot to spindle. The Jelco SA-250ST is 210mm pivot to spindle. The Jelco SA-250, SA-750D, and SA-750DB are 214mm pivot to spindle. The small difference in length can be eliminated by making a slight (+1mm or -3mm) adjustment of the cartridge position in the headshell.
