30Wx2 high-fidelity power amplifier

This 30W+30W integrated front and rear stage high-fidelity power amplifier has superior performance and is composed of
integrated circuits for overload and overheating protection . The front stage uses high and low tone control composed of low-noise triodes, and the bass pole is 40Hz. Treble 20kHz, with
20dB treble and bass control + maximum output voltage 1V, input sensitivity about 60mV, suitable for any input
OTI composed of TDA integrated circuits. The power amplifier circuit has an output of
30W+30W at a frequency of 20Hz~20kHz and a power supply voltage of 15V, with a distortion of less than 0.5%. This amplifier is an ideal audio device for the home. The core component of
    this power amplifier is the TDA2030A integrated circuit , which has the following features:
    (1) Internal Class A and B power amplifier circuit with high efficiency 6
    (z) Internal circuits such as output short-circuit protection and overheating automatic lockout. When a short circuit occurs, the circuit can automatically limit
its own power consumption to protect the output transistor at a safe operating point.
    (3) The output drive current is large and the output peak current] P-3.5A6
    <4) The harmonic distortion is low.
    (5) AC distortion is small 6
