I purchased a Sound Audio st-14 arm for a diy turntable project I am working on, the base plate looked similar to the sme but after purchasing a clearaudio arm board for sme I realized the Sound Audio base plate does not match the hole pattern on the arm board...now I am wondering if I can just swap Sound Audio base plate for an sme?...the hole pattern for the Sound Audio base plate are...2 1/2"x 1 1/2" for arm board holes...thumb screw holes are 1 3/8" apart...would anyone out there know what the thumb screw distance is for the sme.
