How many critical settings?
1 - Cartridge alignment, or overhang: the simplest is to have the stylus extend 15 mm past the center of the spindle. Do that, and refine that later with an alignment protractor (link at top).
2 - tracking force: adjust by turning the counterweight at rear of arm so that the arm balances, with the stylus just higher than the surface of the record. Without moving the counterweight, turn the dial on the front of it to 0 at the top. Now turn the entire counterweight so the dial reads the tracking force the cartridge needs, often 1.5 gm.
3 - Set the antiskate to match. This is less critical.
4 - Put a record on, clean it, and play it.
Keep them spinning.
