| 摘 要： | 采用了典型的OCL功放电路,为全互补对称式纯甲类DC结构,功放的每一级放大均工作于甲类状态。前置低放中输入级和电压放大级采用线性较好的沃尔漫电路,末级功放中采用2SC5200和2SA1943大功率东芝管并联输出,功率强劲。在音源选择电路中,采用了小型继电器,缩短信号传输线路。

| Abstract: | This amplifier uses a typical OCL power amplifier circuit,for the whole complementary symmetrical Pure Class A DC structure,a larger power amplifier for each stage are working in the CPI.Pre-enter-and lowlevel voltage amplification stage the better Wall diffuse linear circuits,the last stage power amplifier used in high-power Toshiba 2SC5200 and 2SA1943 tube parallel output,a strong power.In addition,in audio source selection circuit,a small relay was used to shorten the signal transmission lines. |
