| 摘 要： | 原有功放电路多采用OCL电路，具有工作性能稳定，动态范围大、动态感强，音质好等优点，但是，该电路也存在着不足之处，一旦一只功放管被损坏，就会扩大故障范围，使整个功放电路不能正常工作，本文通过对原有功放电路的分析，在电路上对原有功放电路进行改进，可以达到弥补、优化原功放电路的目的。

| Abstract: | The former power amplification circuit usually adopts OCL amplifier,which has stationary working condition,a large dynamic range scope,a good feeling in dynamic condition, good tone quatity and so on .But it has also some defects.When one power amplifier transistor is damaged,it will enlarge the scope of the fault and make the whole circuit not working normally. This article improves the former power amplification circuit .The improved circuit can not only remedy the defect of the former but make it better. |
