I bought a Technics clone off the auction site, and according to the Technics overhang gauge and my Stevenson protractor it is aligned properly. However, when I look down on it it does not appear to be square in the headshell (one screw looks further forward than the other). The cartridge appears to be square with the front though. Is this common with cheap headshells, being a bit crooked or the holes are uneven?
