Abstract
Apparatus for high voltage conditioning cathode ray tubes having internal electrodes connected to external base pins includes a container having a pair of electrical contact members therein and passing therethrough to a high voltage potential source and to a conditioning potential source with a liquid having a dielectric strength greater than the dielectric strength of air disposed within the container for immersing the base pins therein to effect contact thereof with the electrical contact members of the container. The high voltage conditioning of the cathode ray tube is effected by a process which includes the steps of indexing a cathode ray tube and first container having electrical contact members therein surrounded by a liquid having a dielectric strength greater than the dielectric strength of air to effect immersion of the base pins of the cathode ray tube in the liquid and contact thereof with the contact members of the container and indexing the cathode ray tube and second container containing contact members connected in common to circuit ground to effect arcing to all of the cathode ray tube electrodes in common.
