It is clear that VU133 was produced by more than one factory and was thus important to the military. We know that this type of rectifier was used to derive the HT supplies for pulsed Radar transmitters.
Visual examination of this valve shows that the cathode tube runs vertically through the finned anode. The anode plates are formed to leave a cylindrical cavity about 5 mm in diameter. The high voltage nature of its design are hinted at by the ceramic insulators holding the anode. The heater wire is folded into a hairpin. The cathode tube is held at the top by a pair of support rods. These are held in the ceramic insulators in opposite corners to the anode supports.
See VU133 for details and another form of construction.
The classic envelope reaches a maximum diameter of 51 mm and excluding the B4 base pins the length is 121 mm.
