The CV4045 is a beam tetrode with flying leads to a B9A base pitch. The CV4043 is the B9A based version. The commercial 6BW6 (also CV2136) is the basis of these special quality valves.
The valve is 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 maximum anode dissipation is 13 Watts
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.
The thin glass tube envelope is 20 mm in diameter and excluding the lead out wires measures 59 mm in length.
