EPLACING A BAD DRIVER
If you believe that a driver is blown, make sure that you have tried replacing
the protective 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 follows:
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 pos
itive 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 15 inch/ pounds of
torque.
Note: Be careful not to over tighten the screws, it may cause the brass insert to
spin.
