The 6K8GT was purpose designed for radio as a mixer or frequency changer. The valve has a common cathode and the triode and hexode control grids are internally connected.The local oscillator would produce 7.5 Volts peak to peak signal from the triode section.The input signal would be coupled to the frequency changer via the top cap connection to grid 3.Our other 6K8GT has a perforated outer screen.The wide glass tube envelope is 29 mm in diameter and, excluding the IO base pins, is 71 mm tall.References: Data-sheet & 1040. Type 6K8GT was first introduced in 1938. See also 1938 adverts. |
