THIS NOTE IS COMMON FOR PRINTED WIR-
ING 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. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and
specified.
• : internal component.
¢
• 2 : nonflammable resistor.
• 1 : fusible resistor.
• C : panel designation.
Note: The components identified by mark ! or dotted line
with mark ! are critical for safety.
Replace only with part number specified.
• U : B+ Line.
• V : B– Line.
• H : 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 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.
