Anti-skate adjustment off Thorens TD 146 with Schopper wand

I just replaced a Nagaoka MP-110 cartridge (with MP-200 stylus) with Nagaoka JT-80BK on my Thorens TD 146 with Schopper wand (TP 11 tonearm).  No real issues with MP-110, just has some hours on it.

I mounted the JT-80 and all adjustment were made and correct (i think).  However, I can't get the tracking force adjusted.  With ZERO tracking force (anti-skate weight removed: the small weights on nylon line) there is still too much anti-skate force.  Tonarm does not track towards spindle on smooth vinyl (black side of one sided record).  When I used a test record, the tonearm would not advance (skipping back playing the same thing over and over).  

I can't seen to solve this problem.  There we no issues with the table with MP-110.  Using Hi-Fi News Analogue Test LP, the MP-110 did fine.

Sorry, but I may not be using the correct vocabulary.  

Can you help me diagnose issue?  Or do I need to abandon JT-80 (ouch, $500)?

Thanks for listening.

I never owned a Thorens with that feature. Perhaps someone else can help you.

If you readjusted VTA by lowering the pivot to accommodate the cartridge, that’s probably what caused the problem. Happens to the best of us.

Not that AS failed, necessarily. Rather that something is impeding the horizontal travel of the arm toward the spindle. Usual suspects are tonearm wires fouling the pivot, cuing device set too high so it fouls the arm wand, and then maybe the AS. You can solve this.
