CIRCUIT DESCRIPTION
[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 resistor without any symbol is ohm-type resis-
tor. 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 sym-
bol 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 Digi-
tal Multimeter between such a section and the chassis with no sig-
nal given.
1. In the tuner section,
indicates AM
indicates FM stereo
2. In the CD section, the CD is stopped.
• Parts marked with “
“ (
) are important for main-
taining the safety of the set. Be sure to replace these parts with
