I imagine they figured it could have similar characteristics of the 6l6 beam power with similar output power capability, but with a top cap for the plate, since the flyback transformer in tvs tends to generate high voltage spikes in the plate circuit of the tube, and to place the plate along with other pins.

Next came the 6b4g 19356 which is essentially a 6a3 using the then newly introduced octal 8 pin base. Unlike traditional 6b4gs, which consist of dual triodes connected in parallel inside the tubes envelope, the sovtek 6b4g utilizes a single triode design with a directly heated cathode element. It gives crips low distortion audio output and transformers designed for el84 can use this tube. The 6b4g is an unusual valve in that the envelope holds two triode valves that are hard wired in parallel. The 6b4g appears to have been a popular variant of the 2a3 used in amplification into the 1950s but is rarely used today in comparison with the 2a3.
