The CV1052 UK service valve is equivalent to an EL32 audio output pentode. The power is small at 3.6 Watts but more than adequate for single ended audio output stages in receivers.
The classic envelope is 33 mm in diameter and, excluding the IO base pins, is 91 mm tall.
References: Data-sheet & 1043. Type CV1052 was first introduced in 1940. See also 1940 adverts.
