15 Watt Power Amplifier Assembly (A6) (SS-4100853-501) Removal/Replacement.

Remove/replace the power amplifier (PA) assembly (A1A6) as follows:

a.

Place the bi-directional repeater upside down.

b.

Remove the bi-directional repeater bottom cover.

c.

Pull clamps away from connector on J4 on parent board. Remove connector of amplifier control cable
assembly (A6W1).

d.

Turn bi-directional repeater over; leave cover off.

e.

The 15 watt power amplifier assembly (A6) (1, Figure 7-2) is mounted on the top of the bi-directional
repeater chassis (13). First, unscrew the 20 captive screws (2, Figure 7-3) that hold the PA assembly
to the chassis. Grasp one of the heatsink fins and slightly raise the front end of the PA assembly.

f.

Use a 5/16" wrench to unscrew the cable connector on coaxial RF cable assembly W5 from connector
J2 (RF IN/OUT) on the PA assembly and pull the cable from the connection.

g.

Use a 5/16" wrench to unscrew the cable connector on coaxial RF cable assembly W9 from connector
A7J4 on inner back panel of the BDR unit and pull the cable from the connection.

h.

Detach the amplifier power cable (A6W9) at the in-line plug connector.

i.

Lift the 15 watt power amplifier assembly from the bi-directional repeater unit.

j.

To replace, reverse the above steps.
