1. Specifications

C. Lower the PCB (solder side up) into place on

top of the transformer cup. There are holes in

each corner of the PCB that align with the locator

pins on the cup. The transistors (on PCB edges)

should rest lightly on the transistor spring clips

(14). Place the transformer primary connector

wires into the slot on the PCB.

NOTE: If no further servicing is required, use the

simplified steps below to reassemble the unit.

D. Replace the heatsink (9) using Procedure 6,

steps A and B.

E. Place the transformer primary into the slot on

the Amplifier PCB (11).

F. Secure the adapter bracket (8) and Main PCB

(5) using Procedure 6, step C.

G. Secure the heatsink, adapter bracket and

Main PCB to the module with 6 screws (10).

H. Replace the cover (3) using Procedure 2.

9. Transformer Assembly Removal

NOTE: If direct access to the transformer is

required and the unit has not been

disassembled, refer to the simplified steps

provided in Procedure 7, along with step A of

this procedure.

A. Remove 4 screws (15) and 4 washers (16)

using a 3/32-inch Allen wrench and lift the

transformer assembly (18) out of the transformer

cup.

NOTE: With the module's label side facing you,

the transformer's primary side is on the left and

the secondary side is on the right.

10. Transformer Assembly Replacement

NOTE: The transformer bracket (part of the

assembly) has a bent flange in one corner that

will only allow the transformer to fit in the

transformer cup (19) one way.

A. Lower the transformer assembly (18) into the

transformer cup.

B. Align the screw holes on the transformer with

those on the cup.

C. Secure the transformer to the cup with 4

screws (15) and 4 washers (16) using a 3/32-inch

Allen wrench.

NOTE: If no further servicing of the unit is

required, refer to the simplified steps provided in

Procedure 8 to reassemble the unit.

11. Transformer Cup and Gasket Removal

NOTE: To directly access the transformer cup

and gasket, follow the simplified steps provided

in Procedure 9, then proceed with steps A and

B of this procedure.

A. Remove 2 screws (10) that secure the

transformer cup (19) to the module and lift the

transformer cup away from the module.

NOTE: There might be woofer connector wires

(safety controlled cable (24)) taped over the

transformer cup gasket (20). Note the location of

the cable relative to the module. Remove the

tape and move the wires aside.

B. Remove the transformer cup gasket.

12. Transformer Cup and Gasket Replacement

NOTE: The transformer cup gasket (20) has

raised edges that should be face up when

positioned in the transformer cup. The gasket

also has a U-shaped opening that aligns

precisely with the module.

A. Place the gasket in position over the opening

of the module.

B. Lay the woofer cable (24) over the appropriate

corner of the bass module. The wires must cross

over the top of the gasket.

C. Position the transformer cup. The cup has a

locating ridge and only fits into the module one

way. The lip should be aligned with the U-shaped

opening in the module.
