      Good Evening!

       

      Last night I wanted to change the cable connecting my Vibroplex Codewarrior Jr. from ¼” to ⅛” jack. I received both cables when I got the paddles. I took the original cable off and then got called away and, foolishly, forgot to document which connector went to which terminal. Just to make it a little less clear both cables have different color conductors.

       

      ¼” has blue, white, and bare copper

      ⅛” has red, white, and yellow

       

      Does anyone know the correct placement for each of these cables?

       

      Thanks!

        Use an ohm meter to ring out the conductors.

          I was able to borrow a multimeter (mine is broken) and check continuity on each conductor.

          • tip=dit
          • ring=dah
          • sleeve=ground

          They’re labeled now.

          Thanks,

          Harry
