I do think WTL needs more instruction on how to set up the LTD tonearm. Some things seem overly difficult.
Agreed. The arm is a Royal Pain to dial in!
Without markings to reference all adjustments are made flying blind.
One tip for you is to get yellow electricians tape, about an inch in length x 2 pieces. Using a fine tip felt marker make hash lines 1/8” apart. In the middle make one line longer and make an arrow tip on it.
Place one piece of tape on the tower next to the base. The other tape goes on the base perpendicular to the arm tower. Now you can keep track of your starting point and incremental changes in height or rotation.
My version of the alignment tape. It’s still a vexing procedure but now you have a fighting chance!
Good luck!
