• Note for Printed Wiring Boards and Schematic Diagrams
Note on Printed Wiring Boards:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
•
: internal component.
f
•
: 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
(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.
• DIAT AMP board is multi-layer printed board.
However, the patterns of intermediate layers have not been
included in diagrams.

Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and

specified.
•
: internal component.
f
• 2 : nonflammable 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.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
Note: When mesurering voltages and waveforms, con-
nect with HCD-SB500W (HCD-SB500W states:
DVD play).
no mark : DVD PLAY
∗
: Impossible to measure
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
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.
