Features and Specifications
3940 headphone amp
Refer to SOLO, Lehmann! The mainstream op amp + transistor follows the circuit structure. Support to replace the op amp by yourself! Internal integrated linear voltage regulator circuit, working voltage ±15V, can fully play the sound quality of the op amp, the components use the famous NE5532, which is known as the "Operational Emperor", the sound is full and warm, and the midrange bass performance is excellent! For the transistor, the BD139/BD140 used by many famous amps!
