The Reference Phono 3SE phono preamplifier is housed in a single chassis with heavy, machined aluminum side panels and special acrylic top and bottom covers for the best sound. The vacuum-tube audio stage utilizes six 6H30 vacuum tubes (three per channel), while one 6H30 and a 6550WE provide regulation in the power supply. The large, vacuum fluorescent display on the front panel shows all functions relative to the selected input.
