Thanks, Clabe.
The Mint is much more accurate than the SME paper protractor. The pin hole for the stylus on my SME protractor was not quite in the center and sighting the arm tube from above to be parallel to the printed lines on the paper as they recommend is just not as accurate as placing your stylus on a very thin arc designed for your specific arm and cartirdge combination. The Mint is excellent for Zenith correction-the lateral rotation of the cartridge around the stylus tip-which contrary to popular belief, can be slightly adjusted on the SME fixed-hole headshell, ie. the cartridge can be slightly rotated so that the cantilever can align with the parallel lines at the Mint null points. Azimuth can also be slightly adjusted on the SME by tilting the arm base left or right before tightening the set screws.
It will take a couple of weeks to order the Mint, but once your PC-1 is properly aligned, you may be pleasantly surprised by the improvement in bass and sonics in general. Let us know how it goes.
