Recommended at 30–120mA for optimal thermal stability and sound quality.

Typically 100W to 300W depending on the number of output transistor pairs and supply voltage.

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 shemy usilitelej lanzar

Commonly ranges from ±35V to ±70V DC, depending on the intended load. Assembly & Configuration Tips

A "Lite" version typically uses one pair of output transistors for ~100W at 4 ohms, while standard versions use two or more pairs to achieve 200W+. Recommended at 30–120mA for optimal thermal stability and

The Lanzar design is a classic time-tested symmetrical circuit utilizing bipolar transistors.

For the best performance and to avoid one side "pulling" more current, matching the gain of the output transistors is highly recommended. It is favored by hobbyists for its reliability,

The design is engineered for low-noise performance, making it suitable for high-quality audio reproduction. Key Performance Specs (DIY Module)
