Sensibly equivalent¶ to:
The CV593 is sensibly equivalent to the commercial GZ32 and is a medium power full wave rectifier for general purpose use. It probably would have been used in audio power amplifiers or modest radio transmitters or communications receivers.
This Russian made exhibit is labelled as GZ32, CV593 and 52KU The 52KU exhibit has more images of this valve.
The maximum reservoir capacitor was 60 µF and the minimum series resistance to limit current was 150 Ohms.
The wide glass tube envelope is 28 mm in diameter and, excluding the IO base pins, is 80 mm tall.
