AM/FM Stereo Tuner
– Identify the cables from
CONN6
on the FM tuner PWB (Stereo Out). Identify the Right
Channel output cable, which was marked in a previous step. Remove the shield wire as it
will not be used. Connect the white wire to
position #2
on
SW2a
(FM Stereo). Solder.
– Connect the other cable from
CONN6
on the FM tuner PWB to
position #2
on
SW2b
.
Solder. Remove the shield wire as it will not be used.
– Identify the cable from
CONN2
on the FM tuner PWB (Audio Out). Remove the shield
wire as it will not be used. Connect the white wire to
position #3
on
SW2a
(FM). Do not
solder.
– Cut a 2-inch #22 white wire. Connect one end to
position #3
on
SW2a
. Solder (2 wires).
Connect the other end of the white wire to
position #3
on
SW2b
. Solder.
– Prepare two 24-inch long audio cables. Attach connector pins to each of the two wires on
one end of each audio cable. Insert the connector pins into the socket housing as follows:
for wire one – shield to position #1, white to position #2; for wire two – white to position
#3, shield to position #4.
– Place a mark using a pen or “magic marker” on the free end of the cable connected to
position #1/2 in the above step. This will facilitate connections later on switch SW2.
– Cut a short piece of heat-shrink tubing. Place over both cables and position at the Molex
connector. Process.
– Cut two short pieces of heat-shrink tubing, each about 3/4-inch long. Place the tubing at
the free end of each audio cable. Process.
– Insert the Molex socket into the
CONN3
(Tuning Indicator) connector on the AM tuner
PWB. Note that the drain wires go to the outside positions.
– Route the cables to the front panel output switch using the available cable clamp alongside
the AM tuner PWB.
– Using the cable from
CONN3
on the AM tuner PWB positions #1/2 (the marked cable),
connect the white wire to the unused wiper arm on SW2 nearest the front panel. This is
SW2c
. Solder. Remove the shield wire as it will not be used.
