– 29 – – 30 –6-5. SCHEMATIC DIAGRAM – MAIN Board (1/4) –• See page 37 for Waveforms. • See page 38 for IC Block Diagram.
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 1/4 W or less unless otherwise
specified.
•% : indicates tolerance.
•A: 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 in
playback mode.
no mark : PLAYBACK
∗: Impossible to measure
•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
Note:The components identified by mark 0 or dotted line
with mark 0 are critical for safety.
Replace only with part number specified.
•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
•Circled numbers refer to waveforms.
•Signal path.
