If 1.4volt valves were to be employed it would be possible to fit the the batteries inside the cabinet.
Possibly a chance to use the 1D8GT diode-triode-pentode. The output transformer can be fitted under the chassis.

I doubt if ever Bush Radio considered this valve being a firm that almost always chose Mullard as the supplier of valves and tubes.
