• Schematic diagram and Wiring Side of P.W.Board for this
model are subject to change for improvement without prior
notice.
• 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.
• Resistor:
To differentiate the units of resistors, the 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 an
ohm resistor. The resistor designated "Fusible" is a fuse type
resistor
• 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
(P.P.): Polypropylene 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.
