ABSTRACT In the manufacture of cathode ray tubes, the neck of the tube consisting of a lead-containing glass is closed by a glass base plate having sealed therein a number of contact pins on which an electrode system for generating at least two electron beams is mounted. The periphery of the base plate is sealed to the wall of the neck of the tube by local heating, the base plate being supported by a supporting member having guide holes and reference holes cooperating with the contact pins to determine the centering and the rotational position of the electrode system relative to a re- ference system of axes. In order to prevent (or inhibit) the lead released from the lead-containing glass during sealing from penetrating into the reference holes, said reference holes are substantially spaced from the base plate. This is realised in a simple manner by means of a supporting member in which each reference hole is coaxial with a guide hole and spaced from the surface of the member supporting the base plate. -12-
