NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS

(In addition to this, the necessary note is printed in each block)
Note on Printed Wiring Boards:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
W : indicates side identified with part number.
•
• f : internal component.
• : Pattern from the side which enables seeing.
• Indication of transistor.
C

These are omitted.
Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and
1
/ W or less unless otherwise

specified.
• f : internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
Note: The components identified by mark 0 or dotted line
with mark 0 are critical for safety.
Replace only with part number specified.
• A : B+ Line.
• B : B– Line.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
F : TUNER
J : CD PLAY (ANALOG)
c : CD PLAY (DIGITAL OUT)
E : TAPE PLAY (DECK A)
d : TAPE PLAY (DECK B)
G : REC
q : VIDEO IN (AUDIO)
j : GAME IN (AUDIO)
k : GAME IN (VIDEO)
