This machine is completed by referring to the core circuit of Baishitong BP-26 fever pre-stage.Baishitong BP-26 is a 30,000 yuan level pure fever music fully balanced pre-stage. It adopts Class A line amplification technology and directly amplifies the signal source, which reduces the distortion, phase shift and nonlinearity that occur in the operation of the transistor circuit. distortion. Make the music signal high fidelity after being amplified by the previous stage, truly reproduce the dynamic music details, the sound is warm and delicate, and dynamicThe core amplifier circuit of this machine adopts modular design, the layout of the whole page is simple and reasonable. The materials used refer to the original machine circuit, which is fat and thin. Over-compensated components will make the sound lose its original charm. The power transformer uses a customized all-copper O cattle to reduce magnetic leakage interference as much as possible.
