3-1. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
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
specified.
¢
•
: internal component.
1
4
/
W or less unless otherwise
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
Note: The components identified by mark ! or dotted line
with mark ! are critical for safety.
Replace only with part number specified.
• U : B+ Line.
• V : B– Line.
• Voltages are dc with respect to ground under no-signal
conditions.
no mark : TUNER
• V oltages are tak en with a V OM (Input impedance 10 MΩ).
Voltage var iations may be noted due to normal production tolerances.
• Signal path.
F : TUNER
E : PB (TAPE1/DAT)
a : REC
d : PB (TAPE2/MD)
J : CD
I : PHONO
Note on Printed Wiring Boards:
• Y : parts extracted from the component side.
¢
•
: internal component.
• b : Pattern from the side which enables seeing.
• Indication of diode
D
This marking side is cathode.
