EPLACING A BAD DRIVER
If you believe that a driver is blown make sure that you have tried replacing the pro-
tective resistor before you replace the driver. No sound coming from a driver is often a blown
resistor and not a bad driver. If you need to replace a driver do so as follow:
1 Using the supplied Allen wrench, remove the machine screws
holding the driver in place.
2 Insert the Allen wrench into one of the driver screw holes 1/8”.
Gently lift out the driver and place it onto the foam pad covering
the front baffle.
Note: it is best to place an old towel under the driver so that you will not damage the
enclosure when unsoldering the driver.
3 Using a 900 degree F soldering iron heat, up the solder joints and remove the
driver.
4 Melt a small 1/8” diameter bead of solder onto the tip of each wire, heat the
wire up until you see the solder wick into the copper.
5 Place the replacement driver onto the cloth and solder on the wires to the
driver. White wire to the positive side and black to the negative. The positive
side is generally indicated by a red dot. Make sure to heat up the solder joint
completely and hold firmly in place until the solder sets.
6 Replace the driver foam gasket.
7 Place the driver into the machined recess.
8 Replace the machine screws, tightening them to 20 inch/ pounds of
torque.
Note: Be careful not to over tighten the screws, it may cause the brass insert to spin.
