It helps with voltage regulation, ensuring a stable power supply to the transistors.

A958 Transistor:

Similarly, the A958 is a PNP transistor that assists in achieving proper biasing and signal amplification. It is often employed in audio amplifier circuits to amplify weak audio signals before they reach the power transistors. The A958 transistor is known for its low power dissipation, making it suitable for low to medium power amplification needs.

BC557 Transistor:

The BC557 is a commonly used PNP Bipolar Junction Transistor (BJT) that is primarily designed for amplification and switching purposes. It is a low power, general-purpose transistor with a maximum current rating of 100mA and a maximum voltage rating of 45V.

The BC557 transistor is housed in a TO-92 package, which is small and easy to mount on a printed circuit board (PCB). It has three terminals: the emitter, the base, and the collector. The emitter current is controlled by the base current, making it suitable for various application circuits, such as amplifiers, audio preamplifiers, voltage regulators, and switching applications.

With its high current gain and low saturation voltage, the BC557 is often used as a driver transistor in small signal amplifier stages, where it helps to amplify weak signals while minimizing distortion. Moreover, it is widely used in audio circuits as it has a low noise characteristic.
