DIAGRAMS
2-1. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
Note on Printed Wiring Board:
• X : parts extracted from the component side.
• b : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
• Indication of transistor.
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.
• 2 : nonflammable resistor.
• C : panel designation.
• U : B+ Line.
• V : B– Line.
• Voltages are dc with respect to ground under no-signal
conditions.
no mark : AUDIO
• Voltages are taken with a VOM (input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F : AUDIO
• Abbreviation
CND : Canadian model
G : German model
MY : Malaysia model
SP : Singapore model
Note:
The components identi-
fied by mark ! or dotted
line with mark ! are criti-
cal for safety.
Replace only with part
number specified.
Note:
Les composants identifiés par
une marque ! sont critiques
pour la sécurité.
Ne les remplacer que par une
piéce portant le numéro
spécifié.
