The ECC70 represents the smallest all glass valves made for general use and dates from 1950. This double triode is of low impedance and moderate gain. The fact that Mullard made these valves in the 6021 special quality version suggests a military or industrial role. The wire ended construction would aid the building of small equipment.The thin glass tube envelope is 9 mm in diameter and, excluding the B8D base pins, is 36 mm tall.References: Data-sheet & 1040. Type ECC70 was first introduced in 1950. See also 1950 adverts. |
