Note:
•
X
: parts extracted from the component side.
•
Y
: parts extracted from the conductor side.
•

: Through hole.
•
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
•
A
: B+ Line.

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