The 6X5GT/G is a standard HT rectifier for low power AC mains driven equipment. It was of a type made by several manufacturers, in this case Sylvania. When supplied to the American government it was called the VT-126B.
The output of a centre tapped transformer would be applied to the anodes, the rating given is 325-0-325, the common cathode would be the output for the rectified voltage. A effective series resistance of 350 Ohms was required to limit surges and the reservoir capacitor had to be restricted to 16 µF.
The picture shows the two anodes stacked vertically on the common cathode tube.

The wide glass tube envelope of the top valve is 28 mm in diameter and excluding the IO base pins the valve is 67 mm tall.
