AUDIO OUTPUT JACK’S

CONFIGURATION

HALOWAT TR-5 Version 2

    The left hand jack, labeled loud, which is a single-circuit jack, is used to conduct the plate current from the Second audio tube (UX 112),  to the loudspeaker. This jack has the additional feature of serving as a switch in the filament line to turn on the second Audio Tube (UX 112), when the loudspeaker is plugged in. Thus, when this jack is not in use total power consumption is reduced.  

 

    The centre jack, labeled medium, is used for headphone reception from long-distance stations or loudspeaker reception of nearby stations, enough volume being obtained without the use of the Second Audio Tube (UX 112). In such a double-jack arrangement the filament of the Second Audio Tube (UX 112) is automatically disconnected when the plug is removed from the left hand jack labeled loud.
