ABSTRACT:
A high resistance body for supplying the high voltage of an anode terminal to the electrodes of an electron gun is coil-shaped. The anode terminal is mounted on the funnel portion of a glass bulb, and overlapped by a first conducting layer. The anode terminal is electrically connected to the electrodes of the electron gun comprising the coil-shaped high resistance body, second conducting layer and metal strip. The equivalent circuit comprises a resistance and condenser connected in parallel, at least an inductance generated by the coil-shaped high resistance body connected in series to the resistance, and the electrodes of the electron gun.
