3-1. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
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
Note on Schematic Diagrams:
• 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.
•
¢
: internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
• U : B+ Line.
• V : B– Line.
• Voltages are dc with respect to ground under no-signal
conditions.
no mark : TUNER
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F : TUNER
E : TAPE1/DAT IN
a : REC OUT
d : TAPE2/MD IN
J : CD
I : PHONO
Note: The components identified by mark ! or dotted line
with mark ! are critical for safety.
Replace only with part number specified.
This marking side is cathode.
