The 5U4G rectifier delivers 100 Watts of DC power. It would be used for all types of medium power equipment.

We have no exact details of design age, but these devices were used in the 1940s and 1950s. They were not specified for new equipment by the 1960s.

The sample shown here has a shaped base and looks quite dated.

The classic envelope is 48 mm in diameter and, excluding the IO base pins, is 117 mm tall.
