DIAGRAMS
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 Ω and
1

W or less unless otherwise
specified.
•
f
: internal component.
• 5 : fusible resistor.
• C : panel designation.
For printed wiring boards.
Note:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
•
a

• : Pattern from the side which enables seeing.
• A : B+ Line.
• B : 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.
