Application Notes
12 K.V. cannot be initially applied directly to the tube. The voltage must be gradually increased. The air cooled surface of the plate and the glass seals must be maintained below 140°C. Requires at least 5 cu. ft. of air per minute on the plate radiator and 1 cu. ft. per minute on the grid seal.
