  1. you are a wonder! does the replacement rotary encoder gear have the pre destined fault lines/holes as the original.
    do you also make a replacement part for the arm control nylon(?) hub for a technics sl1500 mk 2

    1. Hi Philip,
      Yes, the encoder gear has the adjustment line on the front face.
      Regarding the second question I will send you an email.
      Kind regards
