think that it is worthwhile for me to add a several pages here detailing soldering technique
please email me.
The A3 connectors are available from Radio Shack as 274-011 'A3F Microphone & Audio
Connector' (female, $4.40) and 274-010 'A3M Microphone & Audio Connector' (male,
$4.20). These connectors are commonly available at all electronics parts stores.
Cut off the old connector and about six inches of cable as the wires sometimes break just
where they come out of the connector. Take one connector apart to get the wire color
scheme you should use for the new connectors. Save all the screws and metal parts.

There are three pins and a connection to the outer shell. I always connect the #1 pin
(ground) to the outer shell pin. Some commercially made cables do not have this
connection. I am sure this practice reduces hum. This may require you to add a short piece
of wire.
Use the old connectors to get the color scheme for the replacements as the color of the
cable wires varies. Use small strips of electrical tape or shrink tubing on the signal joints
for insulation.
4. Taping the Connectors
Wrapping the outside of the connectors with electrical tape helps reduce mechanical
damage, makes the connectors less eye-catching, and shows which cables you have
rebuilt. Use good electrical tape as is lays much better than the cheap stuff; 3M makes all
the best tapes.
There is a trick to getting the tape to lay flat on odd shapes like the connector body. You
control the angle the tape is laying on by intentionally stretching only one side of the tape.
Lay down an inch or so of tape, look to see if it is going the way you want and then stretch
one side only until it is pointing just right. It takes some practice to learn to do this without
wrinkling the tape.
You can also obtain a role of colored table from Radio Shack or the home supply store to
use to make the shielded cables. Simple lay down a band of color a few inches down the
cable from the connector. This will tell you which cables to use for the microphones.
