CAUTION
Use an isolation transformer when performing any
service on this chassis.
When removing a PCB or related component, after
unfastening or changing a wire, be sure to put the wire
back in its original position.
When you exchange IC and Transistor with a heat sink,
apply silicon grease (YG6260M) on the contact section of
the heat sink. Before applying new silicon grease,
remove all the old silicon grease. (Old grease may cause
damages to the IC and Transistor).
