• Power voltage is dc 4.5 V and fed with regulated dc power
supply from DC IN jack (J401).
• Voltages and waveforms are dc with respect to ground in
no-signal conditions.

• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
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.
