您好

      哪个年代您玩过电子管收音机吗？

      这是再生低压直流供电的直流两电子管中波收音机套件 

          制作装备容易，采用低压直流供电。本套件不用电源牛供电，适合对电子管技术比较陌生的初学者 。（本套件采用磁棒线圈，不用接天地线。）随套件给您提供详细电路图，注意检查包装箱。

         由于每个朋友掌握的电子知识不一样，焊接调试套件的能力也不尽相同，有可能有装不响或者接收效果不理想的情况，对此种情况店主无法提供详细的技术指导，请朋友们谅解。只能在挑选元件环节仔细筛选，包装每个元件都是测量好的。

     注意事项：

                     1 请在安装前仔细研究电路图。

                     2 切勿在带电时进行焊接，防止损坏电子管。
