The CV3711 is an audio output pentode with a high mutual conductance, suggesting that full output can be obtained with a low input signal.In class AB1 push pull a pair of valves can deliver 9 Watts at 4.5% distortion. If connected as triodes the pair can deliver 6.3 Watts at 1.6% distortion.The commercial equivalent of this UK Government specification valve is N78.The KB/Z identifies this valve as being made to specification K1001 or K1006, the B denotes qualification by a UK authority and the Z identifies the maker as MO Valve Company, Hammersmith.The thin glass tube envelope is 18 mm in diameter, and excluding the B7G base pins, is 63 mm tall.References: Data-sheet & 1040.
