Help:Anti skate on Tonearm with no anti-skate

Hi Guys

I am having trouble with my right channel having distortion/mistracking. When i place my cartridge on a Cardas Test disk it shoots towards the center very quickly instead of very slowing. This points to a lack of antiskate on the outside of the tonearm(Right Channel).

The tone arm i am using is a 1990's Ortofon RMG309i Tonearm which has not antiskate settings. In the instruction manual it states it has built in antiskate bias.

My question is how do i increase the antiskate because i have a feeling this is the cause of the distortion/mistracking on the right channel.I have checked the VTA, VTF and Azimuth and they all sound correct. My Cartridge is a Shindo Ortofon SPU.

Any help would be great.

I don't think the OP was suggesting the mis-track is only occurring on test discs.(?)

The fact that the arm skips towards the centre suggests that incorrect platter level could actually be part of the problem(???)

Worth re-checking it and fine tuning for a perfectly level surface then re-assess with normal discs.
also check all the wires bellow and possibly inside the tonearm...the bearing must also be in perfect centre from each good is the rubber "dumper" between the weight and arm tube?
Thanks for all your advice. It seems to be a VTA problem. I am using a outrigger armboard, which unfortunately means my tonearm is higher than if it is flat mounted. I am getting a new armboard which allows me to drop the tonearm more to allow the bottom of my Spu to be parallel to the record.

I will post results later this week when new armboard arrives.
This is not antiskating issue, yes.

I have Schick toneam (without antiskating) and once i've bought SPU Spirit cartridge. The sound was just amazing, but i've noticed some miss tracking on severl LPs. My spare SPU Classic tracked same records very well without any problems. I have returned SPU Spirit back to Japan and i'm sure it was NEW, but factory deffected cartridge.
