一台红灯2L1400型立体声台式收录机的右声道音轻,左声道只有爆声,且爆声大小随音量电位器转动而改变.上述现象是立体声收录机的一种常见故障.检修此类故障,首先要判断故障部位,其次才是检修.现介绍一种判断故障的方法.双声道收录机种类很多,电性能和使用功能也各不相同,电路也繁简不一.但所有双声道收录机的基本电路结构和组合方式都有其规律性,只要把握住这些,
A red light 2L1400 Stereo desktop radio right channel sound light, the left channel only burst sound, and the pop sound volume with the volume potentiometer rotation to change the above phenomenon is a common fault Stereo recorders. Overhaul of such failures , First of all to determine the fault location, followed by overhaul. Now introduce a method to determine the fault. Dual-channel recorders a wide range of different types of electrical performance and use functions are also different circuits, but all dual-channel Tape recorders basic circuit structure and composition have their own regularity, as long as the grasp of these,
