Description

Glass octal type used in power supplies of color and black-and-white television receivers and other equip- ment having high dc requirements. Outlines section, 19E; requires octal socket. Vertical mounting is pre- ferred, but horizontal mounting is permissible if pins 2 and 4 are in vertical plane. It is especially important that this tube, like other power-handling tubes, be ade- quately ventilated. For discussion of Rating Chart, refer to Interpretation of Tube Data.
