• Total current is measured with no cassette installed.
• Power voltage is dc 9 V and fed with regulated dc power
• Power voltage is dc 9 V and fed with regulated dc power
supply from battery terminal.
• Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
• Voltages are taken with a VOM (Input impedance 10 M
