The power amplifier circuit is extremely simple, with high signal-to-noise ratio, ultra-low distortion, good tone, high power consumption and high cost performance, and easy to manufacture. Circuit principle: STK4040X1 is a preferred HI-FI power amplifier circuit with excellent electrical parameters: rated output power is not less than 70W and maximum harmonic distortion is only 0.008% under U= plus or minus 42.5V and RL=8 ohms. The typical value is 0.003%, and the 3DB frequency response is 20HZ~20KHZ. Such outstanding performance indicators are indeed rare in the power amplifier circuit. Figure 3-46 is its internal equivalent circuit. The constant current source circuit composed of VT3, R1, VD1, and VD2 acts as a common-emitter impedance of the differential pair tubes VT1 and VT2, and improves the amplification factor of the input stage and the common mode rejection ratio. The single-ended output signal of the differential stage is passed through the VT8 base as an input to the excitation stage. VT7 and VT8 together form an approximate cascode circuit. At the same time, VT7 is the singular connection method. Installation and production: OREMA UN series 12V AGM batteries represent the zenith of sealed lead acid battery technology.
