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 Ω and

4
W or less unless otherwise
specified.
• % : indicates tolerance.
• C : panel designation.
• A : B+ Line.
• Total current is measured with MD installed.
• Power voltage is dc 1.5V and fed with regulated dc power
supply from battery terminal.
• Voltages and waveforms are dc with respect to ground in
playback mode.
no mark : PLAYBACK
( ) : CHARGE
∗
: 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.
