20 W Stereo Integrated Audio Amplifier
– 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.
– Prepare a 4-inch long audio cable. Attach connector pins to each of the two wires on one
end of the audio cable. Insert the connector pins into the 2-conductor Molex socket
housing as follows: white to position #1 and shield to position #2.
– 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 one of the 2-pin Molex sockets into the
CONN101
connector on the preamp PWB.
Note that pin 1 of the Molex socket faces the rear of the chassis.
– Connect the cable from the CONN101 terminal to the
Left Channel Phono Input
jack on
the back panel. The white wire goes to the center pin and the shield goes to the shell.
Solder.
– Insert the other 2-pin Molex socket into the
CONN100
connector on the preamp PWB.
– Connect the cable from the CONN100 terminal to the
Right Channel Phono Input
jack
on the back panel. The white wire goes to the center pin and the shield goes to the shell.
Solder.
– Prepare a 28-inch long audio cable. 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.
– Connect the audio cable just prepared to the
Left Channel Line Input
jack on the back
panel. The white wire goes to the center pin and the shield goes to the shell. Solder.
– Route the audio cable to the front panel along side the preamplifier PWB.
