3. Remove the 26w ribbon cable from the amplifier module which is being replaced. Push outwards on the
vertical clips at each side of the connector, and this will automatically eject the ribbon cable header.
4. At this stage, the module is now electrically isolated from the rest of the circuitry, and can be removed by
turning the amplifier upside-down, and unscrewing the 4 M3 machine screws which go through the chassis
base and into the module. The module will then simply drop out, with its aluminium baseplate intact.
Note: do not remove the Torx screws from the top side of the modules, as this will separate the module
from its baseplate, and is not the correct way to remove the module from the chassis.
The procedure for replacing and re-connecting an amplifier module, is the reverse of this process:
1. Ensure the PSU rails are fully discharged, using the above discharge procedure.
2. Screw the module into the chassis using 4off M3 machine screws.
3. Connect the 26w ribbon cable from the front or rear main PCBs to the module.
4. Connect the speaker output cable to the amplifier module.
5. Finally, connect the small, 4-pin JST connector which provides the high-voltage DC supplies to the
amplifier module.
