Procedure
Step 1: Disconnect the Komri from everything and especially the mains. Pull out
the main fuse compartment to access fuses (located directly under the
mains inlet as shown)
Main fuse
If the Komri has 6.3amp fuses fitted, then remove these and replace with
two10amp MISS 397’s.
There are two other fuses to change, however this requires some
dismantling of the Komri to gain access to them.
Step 2: Position a flat surface at the rear of the speaker
onto which the amplifier module can be laid once it
has been removed. Note the height shown in the
photo. Cover the surface of the bench with
protective foam, a towel/blanket or similar soft
material to protect the heatsink.

foam pad
Step 3: Remove the 10 screws securing the amplifier
module to the cabinet. Leave one of the top
screws until last. Note: although the module is a
precise fit in the cabinet, it’s advisable to hold the
module in place once the last screw has been
removed to ensure that it doesn’t fall out.
Step 4: The module will probably require to be pulled
outwards to release it from the recess in the
cabinet. Grasp the heatsink as shown on the
photo and pull the module away from the cabinet.
Do not allow it to move more than 20mm from the
cabinet. Use the hand resting on the top of the
cabinet to control the movement. (Note: if the
module is hot it will be more difficult to release it
from the cabinet.)
