Note on Schematic Diagram

•All capacitors are in ∝ F unless otherwise noted. pF: ∝∝ F 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.

•f : internal component.

• : B+ Line.

•Power voltage is dc 1.5V and fed with regulated dc power supply from battery terminal.

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

no mark : PLAY

•Voltages are taken with a VOM (Input imped- ance 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 tolerances.

•Circled numbers refer to waveforms.

•Signal path.

F : Audio (Analog)

J : Audio (Digital)

*Replacement of IC601 used in this set requires a special tool.

•The voltage and waveform of CSP (chip size package) cannot be measured, because its lead layout is different from that of conventional IC.
