Extras ▼
The reason type 6C5 disappeared from the lists fairly early is that it was superseded by the 6J5 which had slightly superior ratings and characteristics but was, for all practical purposes, a direct replacement.
Most 6C5s were of the metal-envelope type whereas most 6J5s were 'GT/G' and therefore suitable for a wider range of applications. NB. Type 6SN7GT is two independent 6J5s in one envelope.
The thin metal tube envelope is 25 mm in diameter and, excluding the IO base pins, is 50 mm tall.
Reference: Data-sheet. Type 6C5G was first introduced in 1937. See also 1937 adverts.
