一台收录机收音部分出现高端声音小低端声音大的故障,按理需对其进行统调。但统调是相当烦琐的事,特别是在没有仪器的条件下更令人头痛。笔者受外接天线特性(外接天线如果采用电感耦合方式时高频端电压传输系数小于低频端)启发而采用减少磁性天 A tape radio part of the high-end voice of small low-end voice of the big fault, according to the need to be unified tone. However, the adjustment is a very cumbersome thing, especially in the absence of equipment conditions even more headaches. The author by the external antenna characteristics (external antenna if the use of inductive coupling when the high-frequency voltage transmission coefficient less than the low-end) inspired by the reduction of magnetic days
