· NOTE
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)

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
Jtlets
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

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 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.

How 10 detach the front panel 1. Remove the 4 setscrews ( @ -

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.
