All voltages are measured between the point indicated and the chassis, using a vacuum tube voltmeter. All voltages are
measured with volume control at maximum. STEREO voltages are measured when tuned to a station known to be transmitting
a stereo signal. QUIESCENT voltages are measured with V6 removed from its socket to obtain quiescent condition of the
FMX-3 and the tuning eye. Voltages indicated by ("') vary with signal strength but should always be negative.
