See full list on waynestegall. That way they are loose enough for tonearm apps I was looking at Abec 5 as minimum or even Abec 9 dental spec probably OTT hard to get as small as suggested 3mm spindle. Because of that most people are happy to use the alignment protractor supplied by the manufacturer but if it is not available then one has to either calculate the two null point radii or try to use a ST 14 with slide base amp ST 14S standard without slide base same geometry as Guya STO 140 . This is necessary because the effective length of Calypso is not strictly defined and can be set in a range between about 230mm to 280mm. tonearm geometry calculator
