AMPLIFIER MODULE
To remove the amplifier module from the loudspeaker:
1. Remove the 12 mounting screws. Notice
the 4 corner screws indicated by arrows,
these are not mounting screws, but jack
screw locations.
2. If the amplifier remains fixed to the loudspeaker after removing the
12 mounting screws it is because the amplifier to loudspeaker gasket is
binding them together. To free them, use one or more of the corner
jack locations.
3. To do so replace the keeper screw from a corner location
with one of the mounting screws already removed.
