DIAGRAMS
Note on Printed Wiring Boards.
•
X
: parts extracted from the component side.
•
Y
: parts extracted from the conductor side.
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
Caution:
Pattern face side:
Parts on the pattern face side seen from
(Side B) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Side A) the parts face are indicated.
• These boards are multi-layer printed board. However, the paterns
of intermediate-layer have not been included in the diagram.
Note on Schematic Diagrams.
• All capacitors are in
µ
F unless otherwise noted. (p: pF) 50 WV or
less are not indicated except for electrolytics and tantalums.
• All resistors are in
Ω
and 1 /
4
W or less unless otherwise specified.
• f : internal tolerance.
•
C
: panel designation.
•
A
: B+ Line.
• Power voltage is dc 5.2 V and fed with regulated dc power supply
from terminal (J902).
• Voltages and waveforms are dc with respect to ground under no-
signal (detuned) conditions.
no mark : POWER ON (Set DC IN 5.2V)

• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal production toler-
ances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production toler-
ances.
• Circled numbers refer to waveforms.
• Signal path.
