The M8079 is Mullard's special quality version of the EB91 double diode. These diodes are for signal rectification at medium frequencies eg video.The two diodes are separated by a full height metal plate screen. The anodes are made of two thin plates 10 mm long and 8 mm high, pressed to leave a vertical 2 mm diameter tubular cavity. Into this cavity is fitted the cathode assembly.The thin glass tube envelope is 18 mm in diameter and, excluding the B7G base pins, is 45 mm tall.References: Data-sheet & 1040. Type M8079 was first introduced in 1963. See also 1963 adverts. |
