The NU13 is a majestic piece of glassware. It is a half wave rectifier and the NU13 tells us that this was made for the UK Navy. In 1941 with the advent of the CV register the new name was CV1265.
See NU13A for a later development.
The L4 base is 55 mm square, and is a substantial item. The valve serial number is 4581.
The wide glass tube envelope is 48 mm in diameter and, excluding the L4 base pins, is 158 mm tall.
