• Waveform
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 Ω and
1
/

W or less unless otherwise
specified.
Note: The components identified by mark ! or dotted line
with mark ! are critical for safety.
Replace only with part number specified.
• A : B+ Line.
• Power voltage is dc 4.5 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.
no mark : PB
( ) : REC
• Voltages are taken with a VOM (Input impedance 10 MΩ).
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.
