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

I will check - that may be the issue (lets hope).

Otherwise it will be months with the current shipping times to and from Germany. Other countries seem to a bit better  (except Spain).

Thanks guys!
I played with it last night a bit more, before reading these posts.

No improvement, but the VTA, VTF (1.8g) is OK and the TT is level.
Cannot confirm the overhang and azimuth as I could not have the arm not move to perform those.
It tracks fine until about middle of the record.
The arm is actually mounted on a 1968 Garrard 401 in a heavy DAS plinth, IsoAcoustic GAIA III feet.
I had an Ortofon SA-309 12" for a while (now on my Garrard 301) without any issues, with 2-3 different cartridges.

I will try again tonight after work your above advice.
I had some contact with Frank as well as Ana Mighty Sound (where I got my Scroeder No2 arm) in the past so will try them if not successful.
It is annoying as the sound is really lovely even with the current modest Marantz MA5 monoblocks/SC-7 preamp through SF Cremona Auditors...

Good news - at least for now
spent about 5 min fine tuning the VTA and taking the anti skate screw in and out twice and now all is good 
actually it sounds so good that I really don’t even want to touch it lol

Nope, issue is back however only at about half way through the last song on each LP. Sounds really nice despite all this pain...wil continue tinkering.

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!

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.
