This exhibit is another of the popular 5U4G rectifiers. This one was made by Mullard and is marked 5U4G and not a Mullard own name. Clearly a recognition of the universal acclaim that the 5U4G received.

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

The valve has a maximum diameter of 48 mm and length excluding the IO base pins, is 118 mm.
