Testing a 50 year old mercury arc rectifier

A mercury-arc rectifier is a type of electrical rectifier used for converting high-voltage or high-current alternating current (AC) into direct current (DC). It is a type of cold cathode gas-filled tube, but is unusual in that the cathode, instead of being solid, is made from a pool of liquid mercury and is therefore self-restoring. As a result, mercury-arc valves were much more rugged and long-lasting, and could carry much higher currents than most other types of gas discharge tube.

    Bonjour, je suis un collectionneur de tubes redresseurs au mercure au bras. Devez-vous vendre ou échanger des marchandises, par exemple du matériel ?
