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 M).
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.
