CHAPTER 6. CIRCUIT SCHEMATICS AND PARTS LAYOUT
[1] 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 resis-
tor 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 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), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
• Schematic diagram and Wiring Side of P.W.Board
for this model are subject to change for
improvement without prior notice.
• The indicated voltage in each section is the one
measured by Digital Multimeter between such a
section and the chassis with no signal given.
1. In the tuner section,
    indicates FM stereo
•
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.
