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. The Lanzar design is a classic time-tested symmetrical
The quiescent current must be adjusted on a "warm" amplifier. It is crucial to let the radiator reach operating temperature before final tuning.
