• Power voltage is dc 14.4 V and fed with regulated dc power
supply from battery and accessory terminals.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.

).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
