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.

c : REC (digital)
