 See page 56 for Waveforms.
•
 See page 72 for IC Block 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

W or less unless otherwise
specified.
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

pour la sécurité.
Ne les remplacer que par une
pièce portant le numéro
spécifié.

• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.

• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
