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
specifi ed.
•
f
: internal component.
• C : panel designation.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
• A : B+ Line.
• C : adjustment for repair.
• 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 production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms
• Signal path.

For Printed Wiring Boards.
Note:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• W : indicated side identifi ed with part number.
•
f
: internal component.
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Note:
The components identi-
fi ed by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
number specifi ed.
Note:
Les composants identifi és
par une marque 0 sont
critiques pour la sécurité.
Ne les remplacer que par
une piéce portant le nu-
méro spécifi é.
