Mercury-Vapor Full-Wave Rectifier
The 82 is a full-wave mercury-vapor rectifier tube of the
hot-cathode type for use in suitable rectifying devices
designed to supply d-c power of uniform voltage to
receivers in which the direct current requirement are
subject to considerable variation. The excellent voltage
regulation characteristic of the 82 is due to its low and
practically constant voltage drop (only about 15 volts)
for any current drain up to the full emission of the
filament. The 82 is not interchangeable with any other
rectifier type.
It requires a four-contact socket and should be mounted
in vertical position with the base down.
