cabinet along the upper edge of the first tape, overlapping about 1/8” along the entire length
(photo 4.3d).
Step 7
– Clear the mounting holes by cutting the shielding tape from around the holes with a
hobby knife.
Wiring the Speaker Cable to the Speaker (Combo Cabinet)
Step 1
– Measure a 14” length of white 18AWG wire, and a 14” length of black 18AWG wire.
Step 2
– Twist these black and white wires tightly together the full length.
Step 3
– At one end of this twisted pair, strip the insulation back ½ ” from both wires and tin
these two wires
Step 4
– Unscrew the barrel of the ¼ ” phone plug and solder the
two tinned wires to the plug; white to center and black to shield
(photo 4.3a).
Step 5
– Slide the length of yellow Techflex over this twisted pair
right up to the center conductor of the plug (photo 4.3b).
Step 6
– Slide the 3” length of 3/8” heat shrink up over the
Techflex up to the center conductor of the plug (photo 4.3b).
Step 7
– Shrink the heat shrink in place with a heat gun (photo 4.3b)
Step 8
– Install the remaining 3” heat shrink length over the tech flex at the
opposite end of the twisted pair near the cut end.
Step 9
– Shrink the heat shrink in place with a heat gun.

NOTE
The ¼” phone plug was invented for use in telephone switchboards in 1878. And although it
is no longer used for telephone switching, this great plug has become the standard
connection type between musical instruments and outboard equipment.
CAUTION
Be careful when applying heat to the heatshrink, especially at the point where the techflex
and heatshrink meet. The techflex will quickly melt if excess heat is applied.

To get an even, tight twist, use a handheld drill to twist the two wires together. Place the
loose wire ends into the drill chuck and slowly turn the drill until the wires are tightly
twisted..
