Abstract: A saddle-shaped deflection coil (21) for a cathode ray tube has a beginning (22) of a current-supply wire which is largely detached from a flange (17) of the deflection coil, which flange does not exhibit an impression of the beginning of the current-supply wire. The deflection coil is wound in a manner such that, after winding and baking of the coil the beginning does not have to be pulled loose from the flange, as has been customary hitherto.

Abstract: In a pick-up unit, a tube base for a camera tube is integrated with a coil former having a system of coils. As a result, the length of the pickup unit is small so that it is possible to manufacture portable cameras of small dimensions. The radial position of the tube with respect to the coil former is fixed by centering means provided in the tube base and in a sealing cap engaging the coil former. The axial position of the tube relative to the coil former is fixed by urging the tube against an abutting face of the sealing cap by means of a spring. The coil former is surrounded by a .mu.-metal screening sleeve consisting of two portions. The two portions of the screening sleeve are coupled together by means of a clamping ring.
