The GXU4 is a high power high voltage half wave rectifier. The base is a giant Edison screw and the anode is connected to the top cap.
We have no operating details but the construction is designed to deliver a heavy filament current and the anode connection is well insulated suggesting a high voltage. The anode is enclosed in a metal cage. The circular anode plate is visible through the outer mesh. The filament is within the cage and the electrons emerge from a circular hole 6 mm from the anode. The probability is that the cage is designed to reduce the emission of x-rays from the valve. This rectifier probably operated with a rectified current of 1.2 Amps at 1 - 2 kV.
The wide glass tube envelope is 54 mm in diameter and, including the GES base, is 238 mm tall.
