WAVEFORM

Note on Schematic Diagram: � 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 � and 1/4 W or less unless otherwise specified. � ¢ : internal component. � U : B+ Line. � H : adjustment for repair. � Power voltage is dc 3 V and fed with regulated dc power supply from battery terminal.

� Voltages are dc with respect to ground under no-signal conditions. � Voltages are taken with a VOM (Input impedance 10 M�). 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. F
