– Cut two short pieces of small heat-shrink tubing, each about 3/4-inch long. Place the
tubing at each end of the audio cable. Process.
– Insert the Molex socket into the
CONN103
connector on the preamp PWB. Note that pin
1 of the Molex socket faces the rear of the chassis.
– Connect the cable from the #1/3 position on CONN103 to
Volume Control
R122a. The
white wire goes to terminal #2 (arm). Solder. The shield goes to terminal #1 (low). Solder
(2 wires).
– Connect the cable from the #2/4 position on CONN103 to
Volume Control
R122b. The
white wire goes to terminal #2 (arm). Solder. The shield goes to terminal #1 (low). Solder
(2 wires).
– Using the available tie-wraps, organize the audio cabling into a bundle and route along the
side of the chassis.
– Prepare a 24-inch long piece of
3-conductor
audio cable. Attach crimp terminals to the
red, white, black, and shield wires on one end of the cable. Insert the crimped terminals
into a 12 terminal Molex header as follows:
•
Black to pin #1 (R127a high)
•
White to pin #2 (R127a arm)
•
Red to pin #3 (R127a low)
•
Shield to pin #4 (GND)
– Cut two 3/4-inch long pieces of heat-shrink tubing. Slip one piece over each end of the
audio cable. Process, being careful to not use too much heat.
– Prepare a 25-inch long piece of
3-conductor
audio cable. Attach crimp terminals to the
red, white, black, and shield wires on one end of the cable. Insert the crimped terminals
into the 12 terminal Molex header as follows:
•
Black to pin #5 (R127a high)
•
White to pin #6 (R127a arm)
•
Red to pin #7 (R127a low)
•
Shield to pin #8 (GND)
