For schematic diagrams.
Note:
•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 specifed.
•f: internal component.
Note:
The components identified by mark 0 or dotted
line with mark 0 are critical 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.
•Power voltage is dc 4.5 V and fed with regulated dc power supply
from battery terminal.
•Voltages are dc with respect to ground under no-signal conditions.
no mark : PLAY
•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production toler
ances.
•Circled numbers refer to waveforms.
•Signal path.

Note on Printed Wiring Boards:
Note:
•X: parts extracted from the component side.
•a: Through hole.
•: Pattern from the side which enables seeing.
(The other layers’ patterns are not indicated.)
Caution:
Pattern face side :Parts on the pattern face side seen from the
(Side B) pattern face are indicated.
Parts face side : Parts on the parts face side seen from the
(Side A) parts face are indicated.
