• 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

/
4
W or less unless otherwise
specified.
• C : panel designation.
• U : B+ Line.
• V : B– Line.
• Voltages are dc with respect to ground under no-signal
conditions.
no mark : Power on
( ) : Automatic power off
∗
: Impossible to measure
• 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
AUS : Australian model
CND : Canadian model
Note:
The components identi-
fied by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
number specified.
Note:
Les composants identifiés par
une marque 0 sont critiques
pour la sécurité.
Ne les remplacer que par une
pièce portant le numéro
spécifié.
Note on Printed Wiring Boards:
• X : parts extracted from the component side.
• Y : parts extracted from the component side.
• b : Pattern from the side which enables seeing.
