The EL33 audio output valve is the little brother of the EL37 with which it shares pin connections. Mullard describe this valve as a high sensitivity output pentode for use in AC mains equipment. The EL33 could be used in push pull to deliver 8 Watts, but the normal use was in domestic radio receivers as a single ended stage.
The classic envelope is 42 mm in diameter and, excluding the IO base pins, is 104 mm tall.
