The 417A is a 9-pin miniature triode with an indirectly heated cathode. It is intended primarily for grounded-grid operation in the input stage of broad band amplifiers. Of late it's become a favorite for use in the driver sections of high end tube amplifiers.
The date codes on the boxes are 62-13, and 61-52.
