7-1. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
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.
• b : Pattern from the side which enables seeing.
• Abbreviation
AUS : Australian model
EA : Saudi Arabia model
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
/
4
W or less unless otherwise
specified.
•
f
: internal component.
• C : panel designation.
• U : B+ Line.
• V : B– Line.
• H : adjustment for repair.
• 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
E : TAPE PLAY (DECK A)
d : TAPE PLAY (DECK B)
G : TAPE REC
J : CD PLAY (ANALOG)
c : CD PLAY (DIGITAL)
• Abbreviation
AUS : Australian model
EA : Saudi Arabia model
Note: The components identified by mark 0 or dotted line
with mark 0 are critical for safety.
