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

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 0 sont critiques

pour la sécurité.

Ne les remplacer que par une

piéce portant le numéro

spécifié.

• A : B+ Line.

• Power voltage is dc 1.5V and fed with regulated dc power

supply from battery terminal.

• Voltage and waveforms are dc with respect to ground

under no-signal conditions.

• Voltages are taken with a VOM (Input impedance 10 MΩ).

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.

• Signal path.
