NOTES ON SCHEMATIC DIAGRAM
� Resistor: To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. Besides, the one with �Fusible� is a fuse type. � Capacitor: To indicate the unit of capacitor, a symbol P is used: this symbol P means micro-micro-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression �capacitance/withstand voltage� is used. (CH), (TH), (RH), (UJ): Temperature compensation (ML): Mylar type � The indicated voltage in each section is the one measured by Digital Multimeter between such a section and the chassis with no signal given. � Parts marked with � �( ) are important for maintaining the safety of the set. Be sure to replace these parts with specified ones for maintaining the safety and performance of the set.
