This preamplifier features a toroidal power transformer for extremely low self-noise, a 5U4GB tube rectifier, two OD3 tube regulators, Miflex copper foil coupling capacitors, Vishay resistors and an all film capacitor power supply combine to provide reliable power delivery with excellent bandwidth and beautiful tonality. The Input stage is direct-coupled to the cathode-follower output stage for very low distortion and excellent linearity. 4 sets of stereo inputs and 2 parallel sets of outputs with 5 position variable output level (up to 20 db) all internal wiring is 100% copper.
