Description

Glass octal type used in power supplies of radio and Nc - color and black-and-white television receivers having J2VtfD > high dc requirements. Outlines section, 19E; requires ( J octal socket. This type may be supplied with pins 3, F (£^--^/\ /J)^ 5, and 7 omitted. Vertical mounting is preferred, but \y-tt^ horizontal mounting is permissible if pins 2 and 4 are in vertical plane. The coated filament is designed to ^ 5T operate from the ac line through a step-down transformer. The voltage at the filament terminals should be 5 volts at an average line voltage of 117 volts. It is especially important that this tube, like other power-handling tubes, be adequately ventilated. For discussion of Rating Chart and Opera- tion Characteristics, refer to Interpretation of Tube Data.
