Souga 2A3

About the Souga 2A3

The Kondo Souga is a stereo power amplifier designed to deliver the best performance from 2A3 tubes using a parallel single-ended (PSE) circuit. It features a newly developed driver circuit that unleashes the full potential of the 2A3 tubes, handcrafted module-style amplifier sections, and uses original Kondo parts including pure silver wiring and transformers. The amplifier has a full copper chassis for lively and open sound. Silver output transformers are hand-wound with pure silver wire in a multi-layer, multi-compartment structure for rich and direct sound. Silver capacitors use pure silver foil electrodes designed to prevent oscillation and muddy sound. The internal wiring uses pure silver conductors insulated with natural silk to suppress vibrations. It includes tubes 2A3 x4, 6072 x2, 12BH7 x2, and 5U4GB x1, and has a power consumption of 140W. The amplifier is factory preset for 4Ω or 8Ω speaker output. Dimensions are 430mm (W) x 233mm (H) x 314mm (D) and it weighs 34kg. This amplifier is highly regarded for its natural, detailed, and immersive sound, making it a benchmark for high-end vacuum tube amplifiers.
