The EZ35 is a standard HT rectifier for low power AC mains driven equipment in the immediate post WWII period. 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 350Ω was required to limit surges and the reservoir capacitor had to be restricted to 16 µF. Nothing special and soon replaced by miniature valves of higher specification.
This exhibit is 3 mm shorter than our other EZ35 and the space between the pinch and the lower mica is clearly smaller.
The stacked anodes seen from the side.
The identical anodes, one supported to the left and the other to the right with a common central oxide coated cathode.
The wide glass tube envelope is 29 mm in diameter and, excluding the IO base pins, is 74 mm tall.
