• A : B+ Line.
• Total current is measured with minidisc installed.
• Power voltage is dc 1.5 V and fed with regulated dc power
supply from battery terminal.
• Voltage is dc with respect to ground under no-signal
condition.

• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
