The 6132 is a special quality beam tetrode based on the CV2127 or 6CH6. The design is for a video output valve used under conditions of vibration and shock.
The beam plates are formed from four vertical support rods. The cathode is flat and the grids shaped to pass across the cathode at a constant distance from it.
The end wall of the anode is cut down revealing the two inner grids and the beam plates.

The thin glass tube envelope is 20 mm in diameter, and excluding the B9A base pins, is 60 mm tall.
