Note on Printed Wiring Boards:
• Y : parts extracted from the conductor side.
• a : Through hole.
• b : Pattern from the side which enables seeing.
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.
Common 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
/ W or less unless otherwise
4
specified.
• % : indicates tolerance.
• C : panel designation.
• U : B+ Line.
• Power voltage is dc 4.5 V and fed with regulated dc power
supply from external power voltage jack.
• Voltages and waveforms are dc with respect to ground in
playback mode.
no mark : CD PLAY
∗
: Impossible to measure
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc- w w w
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.
