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.
• Power voltage is dc 9 V and fed with regulated dc power
supply from battery terminal.
• Voltages and waveforms are dc with respect to ground un-
der no-signal (detuned) conditions.

• 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.
• Signal path.
