A104 Assembly Detail
1 – Disconnect the module ribbon cable from the A104
module PCB connector P1.
2 – Loosen the semi-rigid cable coupling nuts at A104
switch J1 input and J2 and J3 outputs.
3 – Disconnect the semi-rigid cable coupling nuts from
both A105 and A106 amplifier J2 outputs and bend each
cable enough to provide enough clearance to disconnect
cables at the switch output ports.
4 – Remove the A105 and A106 amplifier module
mounting screws and slide both modules toward the front
panel while disconnecting the cables at the two A104
output ports.
5 – Remove the four (4) A104 bracket-to-chassis
mounting screws, finish disconnecting the cable at switch
A104 and then remove the module.
6 – Transfer the Switch Control PCB to the replacement
switch module. See
7 – Insert the new A104 assembly into the chassis, then
align and attach the switch J1 input semi-rigid coupling
nut, but do not tighten.
8 – Install the four (4) A104 bracket-to-chassis mounting
screws finger tight; do not yet tighten them.
9 – Slide both the A105 and A106 amplifier modules
back into position and align and finger tighten the
semi-rigid cables coupling nuts at the two A104 output
ports.
10 – Carefully bend the two amplifier output cables back
into position, then align and finger tighten the coupling
nuts to both A105 and A106 amplifier J2 outputs.
11 – Install and finger tighten the A105 and A106
amplifier module mounting screws; do not yet tighten
them.
12 – Torque all semi-rigid coupling nuts to 0.9 N·m (8
lbf·in) using an 8 mm (5/16”) torque wrench.
13 – Tighten the all module mounting screws.
14 – Connect the module ribbon cable to the A104
module PCB connector P1.
