NOTES ON SCHEMATIC DIAGRAM
– 12 –
• 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 pico-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),(RH),(UJ): Temperature compensation
(ML): Mylar type
(S): Styrol type
REF. NO.
POSITIONDESCRIPTION
• The indicated voltage in each section is the one measured by
Digital Multimeter between such a section and the chassis
with no signal given.
• Schematic diagram and Wiring Side of P.W. Board for this
model are subject to change for improvement without prior
notice.
• Parts marked with “ î ” ( ) 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.
