Anti-skate problem with Rega RB303 tonearm

@stringreen , as has been discussed hear on numerous occasions, that is a big mistake. No, it is not an exact science but it will greatly improve tracking of the outer groove wall and reduce record wear. Just one episode of mistracking which is literally the diamond bouncing along the groove wall, will damage a record permanently. Anti skating also maintains the correct orientation of the cantilever so that the magnets and or coils remain in proper alignment. Ideally anti skating should be set at 10% of the VTF. 

I own it and have done the research to death.

Pull the slider all the way to you (front of table).

Even though this is NO anti skating the rega is STILL doing some antiskating.

The cartridge is too light.   Try adding a minuscule amount of downward force and it won't mistrack.   I have listened both ways and like it with no adjustment for a/s.  Using a/s damps the cartridge to close in the sound slightly.   The whole thing is lots of talk with little benefit.  Im using an Ortofon cart for years, and the diamond is still in excellent shape.

it worked properly before?

if so, what changed?
