Description: The Revelation Stereo is a dual-capsule, stereo version of the Revelation tube microphone. Two large-diaphragm, center-terminated capsules are mounted in a fixed 90° array, producing an XY-stereo polar pattern. The Stereo uses a tuned grille cavity intended to reduce standing waves and harmonic distortion. The grille is made of a single layer of heavy-gauge wire mesh. The amplifier circuit employs a pair of Electro-Harmonix EF86 pentode tubes.
