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 1/4 W or less unless otherwise specified.

•% : indicates tolerance.

•¢ : internal component.

•C : panel designation.

•A : B+ Line.

•Power voltage is dc 4.5 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 : PB

( ) : REC

∗: Impossible to measure

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