FIELD: color cathode-ray tubes. SUBSTANCE: electron gun unit has pair of insulating bearing rods, three complanar indirectly heated cathodes positioned between bearing rods, heater for each cathode and pair of advanced reinforced lugs of heater. Heater has pair of pins. Flange strips of heater are envisaged for attachment of heater lugs to bearing rods. Reinforced heater lugs have major body section including two parts. Each of heater lugs has two outwardly directed bottoms. Each of them is connected to one part major body section with two orthogonal pins located between them. EFFECT: improved operational characteristics, enhanced operational stability. 6 cl, 8 dwg
