The CV4043 is a beam tetrode based on the CV2136. Our exhibit is the military version of the 6061, which is in turn the special quality version of the commercial 6BW6. This valve illustrates the reason why the conversion lists seem to have several CV numbers for a single valve. The fact is that for undemanding use they will all work, but for rugged or continuous service the special quality valves can not be replaced by the commercial types and achieve the same reliability or performance.
The valve is described as an audio output beam tetrode, for single ended or push pull use. It was most common in radio transmitters for the audio power stages of the amplitude modulator. In the latter application, with 315 Volts on the anodes, a pair would produce 30 Watts in class AB1.
The 6BW6 can also generate RF power at a few tens of megahertz.
In the 1960s this valve was still current production for its manufacturers Brimar.
See also CV4045 for a flying lead version.
The thin glass tube envelope is 20 mm in diameter and excluding the B9A base pins, is 60 mm tall.
