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 connected, the valve will generate 2.6W at 1.4% distortion.

The GEC paper label differs from the one usually seen as in A2134.

The thin glass tube envelope is 18 mm in diameter and excluding the B7G base pins the length is 62 mm.

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