satisfactorily,

the

more

common

causes

of

trouble

may

generally

be

at-

tributed

to

the

following:

1.

contacts.

Check

the

ponent,

be

sure

to

read

the

How

to

install

the

in

a

wooden

cabinet

1.

Make

a

cabinet

cutout

of

432mm

or

17”

in

width

and

117mm

or

4°°/64”

in

height.

X

8/50”

X

for

supporting

the

amplifier

in

the

bottom

board

of

the

cabinet.

3.

Cut

two

holes

for

attachment

bolts

in

the

bottom

board

of

the

cabinet.

4,

Remove

the

amplifier

from

the

wood

case

(Refer

to

the

section

entitled

“DISASSEMBLY

PROCEDURE”).

5.

Place

the

amplifier

in

position

through

the

cutout.

6.

Make

sure

the

amplifier

is

in

position,

then

put

the

(4X

40mm)

and

fix

the

amplifier

to
