CV2179 is the UK Government procurement designation for the commercial A2134 pentode. This valve carries the M-OV professional trade name of GEC and the A2134 designation.

The literature shows that it was designed as an audio power valve. In class AB1 a pair of valves in push pull will deliver 13.3 Watts. The input needs 30 Volts peak to peak and the anode load has to 7500 Ohms.

In class A triode application the valve will generate 2.6W at 1.4% distortion.

The reverse carries the commercial A2134 code.

The thin glass tube envelope is 18 mm in diameter and excluding the B7G base pins the length is 63 mm.

References: Data-sheet & ¹⁰⁴⁰. Type CV2179 was first introduced in 1955. See also 1955 adverts.
