PROTECTION

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

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.
