Ken Willis makes a custom protractor (Accutrak) for any specific application. Just send him the model turntable and tonearm and also measure the pivot to spindle distance. http://www.audiocircle.com/index.php?topic=97229.0 Manufacturing tolerances vary by a millimeter or two since most table/arm combos are assembled by hand and not on an assembly line. Get a metal ruler from harbor freight for a couple of dollars and measure the distance.
Mint Protractor for the Classic Toneram 10.5i-SE
Does anyone with using a Mint made for this particular tonearm know what parameters Yip used to create it? Specifically, the mounting distance (Pivot to Spindle) and overhang? I saw some posts on here that suggested he uses 259 mm, which is not correct as the P-S is 262 mm. I emailed Yip but no response so far. Thanks.
