Generate a precision printable arc protractor for cartridge alignment. Enter your tonearm's pivot-to-spindle distance, choose an alignment geometry, and download a PDF calibrated to your exact setup.
How to use: Measure the distance from your tonearm pivot to the spindle centre. Print the PDF at exactly 100% scale — verify with the 100mm scale bar before use. The two alignment grids show where your cartridge stylus should sit with zero tracking error.
