The EF732 is one of the last valve types to be designed. The pentode uses lead out wires for direct soldering into circuit as the valve was considered to be as reliable as the rest of the components used in the design.

Sadly we do not as yet have operating details.

The thin glass tube envelope is 10 mm in diameter and, excluding the 8 leadout wires is 34 mm tall.
