The X65 is a triode hexode frequency changer for receiver applications.The triode was designed for local oscillator use and an injection voltage of 10 V peak to peak was produced. The hexode mixer took the signal into the top cap grid, thus maintaining the greatest separation between grid and anode circuits.The Marconi brand label, all Marconi valves were produced by M-OV.The classic envelope is 38 mm in diameter and, excluding the IO base pins, is 100 mm tall.References: Data-sheet & 1040. Type X65 was first introduced in 1937. See also 1937 adverts. |
