DIAGRAMS
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
/
4
W or less unless otherwise
specified.
• % : indicates tolerance.
• f : internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
• A : B+ Line.
• B : B– Line.
•Voltages and waveforms are dc with respect to ground un-
der 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 production
tolerances.
•Waveforms are taken with a oscilloscope.
• Circled numbers refer to waveforms.
• Signal path.
F : FM
J : ANALOG
c : DIGITAL
I : VIDEO
For Printed Wiring Boards.
Note:
• X : parts extracted from the component side.
•
a
: Through hole.
• f : internal component.
• : Pattern from the side which enables seeing.
• Indication of transistor.
Caution:
Pattern face side: Parts on the pattern face side seen from
(Side B) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Side A) the parts face are indicated.
