Caution

If electricity is connected during disassembly, it must be a no load current. If it is load

current, be sure to attach a heat sink to the power-amp IC. This will be damaged if the

above precautions are not followed, as it does not have a sub heat sink attached to it.

Removing the bottom cover (see Fig. 1)

Remove the bottom cover from the main unit.

Loosen and remove the 2 screws C retaining the top

plate on the main unit. (Stoppers are attached to the

backs of the C screws so that they cannot be

removed easily.)

2.

Remove the 4 volume knobs on top of the control

panel. If it cannot be pulled out easily, insert a rope

or wire between the base of the volume knob and the

control panel so that the volume knob is raised a little

above the surface and then remove it.

(Be careful when inserting a lever etc. not to

scratch the surface of the control panel).

Test method

1.

.

Check the voltage and frequency of the secondary

toroidal coil.

2.

Measure the secondary toroidal coil, if the standard

frequency value of 22.87 kHz ± 50 Hz is not attained,

measure the R60 terminal, then adjust the SV01 so

that the R60 terminal becomes 22.87 kHz ± 50Hz.

Caution

If electricity is connected during disassembly, it must be a no load current. If it is load

current, be sure to attach a heat sink to the power-amp IC. This will be damaged if the

above precautions are not followed, as it does not have a sub heat sink attached to it.

Caution

If electricity is connected during disassembly, it must be a no load current. If it is load

current, be sure to attach a heat sink to the power-amp IC. This will be damaged if the

above precautions are not followed, as it does not have a sub heat sink attached to it.

Caution

If electricity is connected during disassembly, it must be a no load current. If it is load

current, be sure to attach a heat sink to the power-amp IC. This will be damaged if the

above precautions are not followed, as it does not have a sub heat sink attached to it.
