• NOTE
• BEFORE STARTING THE REPAIRING
The unit is provided with the speaker circuit protection fuses at the right and left channels respectively. The fuse is to
prevent the power IC from destruction, should the speaker terminals be short-circuited. Accordingly, if the unit fails to
function upon completion of the speaker connections, check the speaker circuit protection fuses first of all for possible
blowing.

• HOW TO REMOVE THE CABINET, BOTTOM BOARD AND FRONT PANEL
How to remove the cabinet
1. Remove the 4 setscrews (CD ~ @ in Fig. 1) on the side and 4 setscrews (@~ ® in Fig. 2) on the back of the cabinet.
2. Shift the cabinet backward and lift it upward. (Arrow G in Fig. 1)
Electrolytic Capacitor
Resistor(500,50W)
r=J
Before adjusting or repairing, be sure to short-circuit
opposite poles of the 8200pF capacitors (C501, 502) with a
resistor approximately of "50[2, 5W" for discharging the
charged voltage .
Short-circuiting with a screw driver and the like is not only
dangerous, but may destroy transistors and diodes, and
should therefore be avoided.

• HOW TO REMOVE THE POWER IC
1. Remove the solder of power IC for both Lch
and Rch.
2. Remove the 3 setscrews (CD - ® in Fig. 5) use
to fasten the heat sink from the center bracket.
3. Remove the heat sink along with power IC in
the direction of arrow G (Fig. 6)
4. Remove the 2 setscrews (@, CID in Fig. 6) used
to secure the power IC on the heat sink, and
then pull the power IC in the direction of arrow

How to detach the bottom board
1. Remove the 4 setscrews (@ ~ @ in Fig. 3) used to
secure bottom board and 4 setscrews ( ® ~ @ in
Fig. 3) for the legs. Then the bottom board can be
detached.
5. When mounting the power IC, apply silicone
compound (or equivalent heat diffuser) to the
back of power I C, and then follow the steps 1
- 4 reversely.
How 10 detach the front panel
1. Remove the 4 setscrews ( @ -
® in Fig. 4) and then
carefully pull the front panel toward you.

Indicated voltage values are the standard values for the unit measured by the
DC electronic circuit tester (high impedance) with the chassis taken as
standard. Therefore, there may exist some errors in the voltage values,
depending on the internal impedance of the DC circuit tester.
c:::=JStandards values
The I1J mark has been used for the indication of specified parts for an
assurance of safety, but it has been changed to L!l mark. When replacing
parts, be sure to use parts with correct numbers with reference to the circuit
drawing or the repair parts list.
