THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this necessary note is printed in each block.)
For schematic diagrams.
Note:
• 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 / W or less unless otherwise
4
specified.
• % : indicates tolerance.
• f : internal component.
• 2 : nonflammable resistor.
• 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 (detuned) conditions.
No mark : FM
• 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.
• Circled numbers refer to waveforms.
• Signal path.
F
: ANALOG
J
: DIGITAL
c : DVD
• Abbrevation
MY : Malaysia model.
SP : Singapore model.
