Custom arc template generator for phono cartridge alignment (also prints strobe disks) V 1.08
http://www.conradhoffman.com/chsw.htm
I *believe* the Pivot-to-Spindle (P-to-S) distance for the AP PL-120 is 230 mm (but you should pull out a handy-dandy ruler to verify).
Enter that P-to-S distance into the tool linked above, select IEC to set your inner / outer groove radii, and "Lofgren A" (which some call "Baerwald").
Print out the template on a good sheet of photo paper, and re-verify the dimensions of the protractor with your handy-dandy ruler.
Use the help button and the readme.txt if you have any questions.
