Rega RP3 Bias/Anti-Skate

Anti Skate on the REGA RP3 should be set to the same as tracking force.Yes you can play around with it while the record is spinning. Be careful ,make small adjusts.

My experience is similar to Viridian's. With Rega style arms and others, I've obtained optimum sonics (to my ears) by setting A/S to one half or less of the scale on the arm. Many high end arms don't have a scale at all. They assume you'll adjust A/S by listening.

The VTF and A/S scales on Regas are notoriously inconsistent from one sample to the next. I'd recommend using a decent scale to get VTF in the ballpark for your cartridge, then adjust both parameters by listening (to music, not test tones).
