The EL3 is an audio output pentode, but the ratings given by Mullard are for a triode. The second set of ratings is from Tungsram for the valve in pentode service.
The classic envelope is 33 mm in diameter and, including the Ct8 base pins is 110 mm tall.
References: Datasheet, 1040 & 1043. Type EL3 was first introduced in 1938.
