THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the 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

specified.
• f : internal component.
• 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.
• H : adjustment for repair.
• Voltages and waveforms are dc with respect to ground un-
der no-signal (detuned) conditions.
no mark: CD STOP
• 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.
