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 W and
1/4
W or less unless otherwise
specified.
¥ % : indicates tolerance.
¥
¢ : internal component.
¥C: panel designation.¥U: B+ Line.
¥ Power voltage is dc 3 V and fed with regulated dc power
supply from battery terminal.
¥ Voltages and waveforms are dc with respect to ground in
playback mode.
¥ Voltages are taken with a VOM (Input impedance 10 MW).
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.
¥ Signal path.
