RE: SME V Setup Problem

" I ended ordering an arc protractor from Accutrak. Ken hooked me up as would a Mint protractor from Yip."

I am unsure using about using generalised arc protractors with the SME V. Calculating the correct arc requires knowing the distance between the stylus and pivot and hence each protractor is unique to the arm/cartridge combination as the precise stylus position is unknown cartridge to cartridge. This is not a problem with most arms as the slotted headshell means that you can change the stylus position in relation to the pivot ( that is what the alignment process does i.e. it is achieving correct effective arm length). With SMEs you cannot do this and the distance is fixed. With SMEs the geometry changes instead the position of pivot to spindle.

I do recall that one rated manufacturer of arc protractors ( it is in fact Yip and Mint) requires SME V owners to measure the distance from stylus to cartridge mounting holes so that the correct arc may be calculated. They say " SME tonearms do not allow Effective Length adjustment, hence we need the MHST distance of your cartridge. Read the following link for more information: SME Tonearms

Note Best Tractors built for SME tonearms are tonearm/turntable/cartridge specific."

Mint also link the Audiogon discussion that I link on this subject.
