dual supply 15v based transistors

This circuit is designed to be integrated into an existing circuit, such as an audio amplifier, which already supplies symmetric voltages of +20V/-20V and +50V/-50V. The schematic diagram is derived from a dual polarity power supply circuit providing +/- 15V based on a transistor power supply. Refer to that page for an explanation of the related circuit diagram.

The circuit in question serves as a dual polarity power supply, which is essential for many electronic applications, particularly in audio amplification where both positive and negative voltages are required for proper signal processing. The power supply is capable of delivering a regulated output of +/- 15V, which is typically used to power operational amplifiers, analog signal processing circuits, and other components that require dual polarity voltages.

The schematic includes a series of transistors configured in a push-pull arrangement, allowing for efficient voltage regulation and current handling. The use of transistors provides advantages such as thermal stability and the ability to handle varying load conditions without significant performance degradation. The circuit may also incorporate additional components such as capacitors for filtering and stabilizing the output voltage, as well as diodes for protection against reverse polarity and voltage spikes.

To integrate this circuit into an existing audio amplifier, it is important to ensure that the input voltage supply is compatible with the specified voltage levels of +20V/-20V or +50V/-50V. The output from the dual polarity power supply should connect to the appropriate points in the amplifier circuit, ensuring that the voltage levels are correctly applied to the operational amplifiers or any other components requiring dual supply voltages.

Additionally, careful consideration should be given to the layout of the circuit to minimize noise and interference, which can be critical in audio applications. Proper grounding techniques and the use of decoupling capacitors can help achieve a clean power supply, enhancing the overall performance of the audio amplifier.

In summary, the integration of this dual polarity power supply circuit into an existing audio amplifier can significantly improve its functionality by providing the necessary voltage levels for optimal operation of various electronic components.This circuit is intended to be transplanted into an existing circuit (eg audio amp), which already provides symmetric voltage between + /-20V and + /-50V.
