The EZ11 is a full wave rectifier from the 1930s with applications in domestic radio receivers. The rectifier was designed to work with 600 Ohms of total series resistance and to feed a maximum of 32 μF of reservoir capacitor.
The makers name and the type designation are stamped into the dome of the envelope. And the German unified armed forces name of Wehrmacht is printed on the side. This term was used between 1936 and 1945. The Footless base was used extensively for German military valves. The glass disc construction and horizontal electrodes gave enhanced performance over the large glass valves.
The wide metal tube envelope is 36 mm in diameter, and excluding the footless base pins is 35 mm tall.
