Arthur Loesch 302 Mono Amplifier

Model 302 Mono Amplifier

 
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 Mono Amplifier 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 switch. Designed for loudspeakers with a minimum efficiency of 91dB/1m, installing either power tube will easily drive your speakers to satisfactory SPL levels in most listening rooms.
 
Sonically, the Model 302 redefines the sound of the 300B, for which it's primarily designed. 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.
 
Model 302 Mono Amplifier

A pair of toggle switches change the filament voltage to allow the use of type 50 output tubes (not included).
