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

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.
