As the main key is a powerful transistor P214A capable of stable operation even without a radiator , thanks to the massive body. As a load in its collector circuit is a speaker or earphone - it is the load resistance determines the quiescent current of the circuit and allows you to sound both high-resistance and low-resistance speakers without reconfiguring the circuit.

High-power transistor provides a low-power transistor MP40 included as an offset for P214A Such a scheme can achieve very high sensitivity because the input is not recommended to leave long wires or better use shielding conductors.
