from the center of the turntable. See figure 1 The arm-nest requires a 3,"16"dia. hole 5-1/2" forward ofthe
arm hole. Locate the arm-rest so that when the arm is on the rest. it will not interfere with placing a record
on the turntable. Provide a 1/4" hole for pickup wiring 1-1/4" left of the hole for the pickup arm.

l3. Provide a five terminal strip within 2" wiring distance of the 1/4" hole provided for wiring. The center
terminal must connect to the metal buseplate of the turntable assembly. therefore. a terminal strip with
center terminal used for mounting is satisfactory. Sec step 4 d

the "U" clamp with the final position of the pickup arm. See figure 1.

nuts on the base mounting stud. below the turntable baseplate.
