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 (1) ~ ④ in Fig. 1) on the side and 4 setscrews (5) ~ ⑧ in Fig. 2) on the back of the cabinet
2. Shift the cabinet backward and lift it upward. (Arrow (3) in Fig. 1)

Fig. 1

How to detach the bottom board

1. Remove the 4 setscrews (10 ~ 13 in Fig. 3) used to secure bottom board and 4 setscrews (10 ~ 17 in Fig. 3) for the legs. Then the bottom board can be detached.

How to detach the front panel

1. Remove the 4 setscrews ( 18 ~ 21) 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. Standards values
9. The SI mark has been used for the indication of specified parts for an assurance of safety, but it has been changed to A mark. When replacing parts, be sure to use parts with correct numbers with reference to the circuit drawing or the repair

10. To represent transistors, Q is used instead of TR (Ex. TR1 -> 01)

BEFORE STARTING THE REPAIRING

Before adjusting or repairing, be sure to short-circuit opposite poles of the 6800µF capacitors (C501, 502) with a resistor approximately of "50Ω, 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
Remove the 2 setscrews (①, ② in Fig. 5) used to secure the power IC on the heat sink, and then pull the power IC in the direction of arrow O.
When mounting the power IC, apply silicone compound (or equivalent heat diffuser) to the back of power IC, and then follow the steps 1 ~ 2 reversely.
