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

U
: B+ Line.
• Total current is measured with Power ON/OFF mode.
• Power voltage is dc 9 V and fed with regulated dc power
supply from external power voltage jack.
• Voltage and waveforms are dc with respect to ground
under no-signal conditions.
no mark : POWER ON
∗
: Impossible to measure
• 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.
