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.

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.
• A : B+ Line.
• Power voltage is dc 3 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.
