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

specified.
f
: internal component.
• C : panel designation.
For printed wiring boards.
Note:
• X : parts extracted from the component side.

: Through hole.
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
• 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 M
Ω).
Voltage variations may be noted due to normal produc-
tion tolerances.
Note:
The components identified by mark 
! or dotted
line with mark 
! are critical for safety.
Replace only with part number specified.
Caution:

Parts on the parts face side seen from
(Side A)
the parts face are indicated.
• 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.
