tonearm issue

I have the Riverstone Audio gauge and it is excellent.   So sensitive that it registers if you breath on it.      Definitely worth the money.  

If the stylus/cartridge slides in off the edge of the LP but stops at the beginning of the grooved area, THAT is normal. Most LPs have a raised peripheral "lip" which causes that to happen. I doubt your gauge is very inaccurate, but by all means to check that out for future reference.

I experience a similar issue on a few records; dropping the needle right at the beginning of the track grooves solves the problem every time.

I also use the Riverstone which is excellent, inexpensive and comes with 2 weights for verification of calibration.

and remember to check for level side to side and front to back. Put the level on the platter, not the plinth.

Could you explain what was done when the arm was serviced. Was it rewired ?

A good test is to balance the arm/cartridge to zero, and set the antiskate to 0, so the arm is floating, and then you can see straight away if the arm has a tendency to swing one way or the other.

I know from being an SME distributor some years ago that often re-wiring had not been dressed correctly where the wire goes from tube to vertical column resulting in excessive pull on the arm one way or the other.
