Help - Scroeder CB-9" tonearm - anti-skating setting issue


Hope someone can help here.
I have an old (original) version of the CB 9" arm which was developed for the Artemis TT.

I acquired it recently after building up the whole Artemis system.

The issue I am facing is that I am struggling to set the ant-skating correctly.
I reduced it so far that the screw is almost falling out, yet the tonearm swings outwards as I am trying to adjust the cartridge using a Dr Feickert rig. Correct VTA/VTF set, using a Fidelity Research FR-1 MK III retyped by Soundsmith.
I can listen to the first 2-3 recordings on the record (so at least I know everything is working fine) but then it starts jumping back (like there is a skip in the record). Tried several records, same result.

Manu al very basic and could not find other posts anywhere.
Thanks in advance!

Sancho, twist the arm in it's mount so that at rest the tonearm is closer to the platter. That should fix it. You can also increase the VTF just a little.
Hi
Is the distortion more prominent in one channel or across them both?
This could be a clue to the problem

Again, a possibility......
Bad in the left channel, too much antiskate, Bad in the right channel, too little antiskate
Bad in both, incorrect alignment.

This is how my CB / Shelter Harmony behaves.
ymmv 

Cheers 

thanks guys I will try tonight!
No distortion, actually plays beautifully until it hits a spot when it starts skipping close to the end of the side.
Made some adjustments and now it seems everything is OK - for now.
Frank also responded and he suggested dates same, but he is concerned that someone might have twisted the wires and eventually he will need to service the arm.
Now there is some issue in the channel (recently serviced vintage Marantz gear) so will trouble shoot that tonight.

Again thank you all it was very helpful - much appreciate the support!
