How to Remove the Meter Circuit Board
Remove the top cover (25). (Refer to section 1).
Remove the single retaining screw (3 x8 CBTS°S tight)
(53) from the shield bracket (60) and detach the shield
bracket.
if you remove the three binding screws (3 X10 CBTS-P
tight) (51) of the meter circuit board, and loosening the two
hooks (large), the meter circuit board can be taken off.
Note: When replacing the tact switch, check to make sure
that it is not floating above the circuit board. If it is
floating, the switch will be in the on condition when
the set is assembled.

bottom cover on the rear side of the chassis.
Only when it is unavoidable should you refer to
the removal method mentioned above.
@ When reassembling, follow the procedures in
the reverse order. However, if each of the various
parts are not assembled properly in their respec-
tive position, the set cannot be assembled in
some cases. Therefore, check the work of each
step carefully when assembling.
How to Remove the Power Supply Circuit
Board
Remove the top cover (25) and the front panel (24). (Refer
to section 1).
Pull the power switch lever (23) from out of the power
supply switch.
Remove the connector with lead wires, which run from the
power supply circuit board, from the audio circuit board.
(Refer to section 5 (4))
Remove the bushing (7) that is fixing the power supply cord
from the chassis (1).
When the four screws (4 x10 CBTS-P tight) (54) (3 x10
CBTS -P tight) (51) that are holding the power transformer
and circuit board are removed, the power supply circuit
board can be removed by raising it.
