Descrizione This lamp is the sprayed red version of the type 313 and was originally designed for use in American aircraft in the late 1930's. Red lamps of this type have been used in sound mixers by musicians for some years because of their voltage being so close to the old 30 volt computer power supplies which have been adapted for the sound mixers. One red glass General Electric 313R has been seen
