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 improve-
ment 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 AM
indicates FM stereo
2. In the main section, a tape is being played back.
3. In the deck section, a tape is being played back.
( ) indicates the record state.
4. In the power section, a tape is being played back.
5. In the CD section, the CD is stopped.
• Parts marked with “ “ ( ) are impor-
tant for maintaining the safety of the set. Be sure to
replace these parts with specified ones for maintain-
ing the safety and performance of the set.
