The Ravensbrook FET FM Tuner is a simplified version of the Ravensbourne 2 Tuner. It incorporates many of the excellent features of its predecessor, including FET transistors in the RF unit, integrated circuits in the IF amplifier and ratio detector, and an identical stereo decoder and metering arrangement. The tuner is available in two configurations: as a chassis for integration into existing furniture, or as a shelf-mounted unit in a wooden case.
