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. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ωand 1/4W or less unless otherwise
specified.
•f: internal component.
•2: nonflammable resistor.
•5: fusible resistor.
•C: panel designation.
For printed wiring boards.
Note:
•X: parts extracted from the component side.
•a: Through hole.
•b: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
•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 and waveforms are dc with respect to ground in
service mode.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
no mark : STOP
• Circled numbers refer to waveforms.
• Signal path.
