W or less unless otherwise
specified.
• % : indicates tolerance.
•
f
: internal component.
• C : panel designation.
• U : B+ Line.
• H : adjustment for repair.
• Total current is measured with a cassette installed.
• Power voltage is dc 1.5 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 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.
