Sensibly equivalent¶ to:
The EK32 octode mixer or frequency changer for superhet receivers.
The local oscillator would be formed by using a grid one as the control grid and grid two as the oscillator anode. Grids three and five are screen grids. Grid four is the signal input grid and grid six is the suppressor grid.
The EK2 from 1938 is electrically identical but on a Ct8 base.
The classic envelope is 29 mm in diameter and, excluding the IO base pins, is 83 mm tall.
References: Data-sheet, 1040 & 1043. Type EK32 was first introduced in 1940.
