NOTE  FOR  PRINTED  WIRING  BOARDS  AND  SCHEMATIC  DIAGRAMS
(In addition to this, the necessary note is printed in each block)
Caution:
Pattern face side:
Parts on the pattern face side seen from
(Conductor Side)
the pattern face are indicated.
Parts face side:
Parts on the parts face side seen from
(Component Side)
the parts face are indicated.
Note on Printed Wiring Boards:
• X
: parts extracted from the component side.
• Y
: parts extracted from the conductor side.
f
: internal component.
• b
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Note on Schematic Diagrams:
• 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

W or less unless otherwise
specified.
f
: internal component.
C
: panel designation.
U
: B+ Line.
H
: adjustment for repair.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from ACC and BATT cords.
• Voltages are taken with a VOM (Input impedance 10 M
).
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.
