3-1. CIRCUIT BOARDS LOCATION
Note on Schematic Diagram:
•All capacitors are in µF unless otherwise noted. (p: pF)
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.
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
piéce portant le numéro
spécifié.
•A: B+ Line.
•B: B– Line.
•Voltage is dc with respect to ground under no-signal
(detuned) condition.
•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
no mark : POWER ON
∗: Impossible to measure
•Signal path.
F: LINE
•Abbreviation
CND : Canadian model.
Note on Printed Wiring Boards:
•X: parts extracted from the component side.
•: Pattern from the side which enables seeing.
