The EK32 frequency changer is of octode construction. The local oscillator would be formed by using a grid as the oscillator anode, and directly modulating the main electron flow.

The EK32 from Mullard also had military versions. The EK2 is electrically identical but is mounted on a Ct8 base.

The classic envelope is 29 mm in diameter and, excluding the IO base pins, is 83 mm tall.
