Since the late 1980s, Dr. Arthur Loesch has been a major figure in the revival of the Single-Ended Triode (SET) amplifier for home audio use.
The Model 302 will be the first release in a series based on his designs. It features a pair of power output tubes, either 300B or type 50, transformer coupled in parallel. The filament voltage for the 300B and 50 power tubes can be switched externally, making them interchangeable with the flip of a lever. Although we recommend the 300B as the tube of choice, either of the two will easily drive the EP-1 Loudspeaker to satisfactory SPL levels in a typical listening room.
Sonically, the 302 is like no other tubed amp you've heard to date. Highs are clear, detailed and undistorted; the midrange is full, rich, and vibrant; and the bass is bold and deep, with an impact usually attributed to solid state equipment. Sound staging is wide, deep, and three-dimensional. These amplifiers present music with the snap and timing of a live performance, sailing through the most difficult recordings, as they lift the last veil between you and the stage.

- Tango Output, Interstage and DC Filter Transformers.
