The (often spelled "Ланзар" in Russian-speaking communities) is a legendary DIY power amplifier circuit known for its symmetrical, high-fidelity Class AB architecture. It is favored by hobbyists for its reliability, relative simplicity, and powerful, "assertive" sound signature that can drive a wide range of speaker systems. Circuit Overview & Design Recommended at 30–120mA for optimal thermal stability and

It features a symmetrical differential input stage, a voltage amplification stage (VAS), and a powerful output stage usually based on Toshiba 2SA1943 and 2SC5200 transistors. It is favored by hobbyists for its reliability,

The quiescent current must be adjusted on a "warm" amplifier. It is crucial to let the radiator reach operating temperature before final tuning.
