SA-PSD5/WPSD5/SS-SPSD5
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
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
1
specified.
• : internal component.
f
• C : panel designation.
Note:
The components identi-
fied by mark 0 or dotted
line with mark 0 are criti-
cal 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 (detuned) conditions.
• 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.
F
: AUDIO (ANALOG)
J
: AUDIO (DIGITAL)
• Abbreviation
CND : Canadian model.
SP : Singapore model.
