Collection: U19, CV187, CV1508, U23, V1913, 10E/520, RECTIFIER, B4
The U19 is a high voltage half wave rectifier with a series resistance of 600 Ohms and a maximum input capacitance rating of 4uF.
The anode is carbonised to aid in radiating away the heat generated in use by the intense electron bombardment and the whole electrode structure smacks of longevity and build quality having been constructed with ceramic supports and insulators.
It is reassuringly vast at 166mm height. Osram first marketed the U19 for Air Ministry use in 1939.
