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.
Parts are safety assurance parts.
When replacing those parts make
sure to use the specified one.
