The quiescent current must be adjusted on a "warm" amplifier. It is crucial to let the radiator reach operating temperature before final tuning.
The output transistors must be mounted on a significant heatsink. Using mica insulators and thermal paste is essential. shemy usilitelej lanzar
The Lanzar design is a classic time-tested symmetrical circuit utilizing bipolar transistors. The quiescent current must be adjusted on a "warm" amplifier

For the best performance and to avoid one side "pulling" more current, matching the gain of the output transistors is highly recommended.
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+.
