东方/高士混合式CD—107型激光唱机系广州市华联电子厂早期产品,由于该机出厂时未配线路图,改装时颇费思索。以下是笔者的改装体会,供电子爱好者参考。一、剖析及准备开启机盖,从布局及元件分析,该混合式CD机只是在音频段设计为晶体管和电子管混合型,在前置级用一按键开关转换,信号既可用晶体管放大输出,也可由两只6N1电子管放大输出。该机采用索尼CD机芯,其DSP芯片为CXD1167Q集成块。改
Oriental / Cohiba hybrid CD-107-type CD player is the Guangzhou Hualian Electronics Factory early products, due to the aircraft is not equipped with the wiring diagram when the factory, when the conversion cost a lot of thought. The following is the author’s conversion experience, for electronic enthusiasts reference. First, the analysis and preparation Open the lid, from the layout and component analysis, the hybrid CD player is designed for the audio segment mixed transistor and tube, the front stage with a key switch to switch, the signal can be amplified by the transistor output, but also Can be amplified by two 6N1 tube output. The machine uses Sony CD movement, the DSP chip for the CXD1167Q manifold. change
