2-1. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
Note on Printed Wiring Board:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
•
(The other layers' patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen from
(Conductor Side) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Component Side) the parts face are indicated.
• Indication of transistor
: Pattern from the side which enables seeing.

These are omitted.
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/
specified.
• 5 : fusible resistor.
• C : panel designation.
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.
• B : B– Line.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : CD PLAY (ANALOG OUT)
〈〈 〉〉 : CD PLAY (DIGITAL OUT)
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage var iations may be noted due to normal production tolerances.
• Waveforms are taken with a oscilloscope.
Voltage var iations may be noted due to normal production tolerances.
• Circled numbers refer to waveforms.
• Signal path.
J : SACD PLAY
c : CD PLAY (ANALOG OUT)
I : CD PLAY (DIGITAL OUT)
