普通的元件,不普通的音效.胆石混合式袖珍小功放.

最近刚完成了一台胆石混合式袖珍小,所用的元件都很普通.功率输出用2955.3055对管,整流用6H2,前级放大管用6F1,这种管在音响电路中很少使用.我手里有几只一直想用上它,所以设计了这个电路.有图.<img src="attachments/94kk/20062621281503.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window

机壳好象自制的，介绍一下

回乐版.机壳是用铝合金门窗型材制作的,宽10厘米,高3厘米的那一种,截22厘米长,变压器是自己绕的,数据是经过计算后得出的.输出双14W的音频功率,变压器的功率为70W,余量不大将够用.下面的工作是作一个变压器罩,这样就完美了.

谢谢喜版夸奖,铝合金型材好加工,制作小型的机壳也不花什么钱.所以才用它的.

谢谢tjondata老师,因家里没数码相机照一次像不容易.还有一些照片没发,如内部结构,印刷电路板电源和喇叭保护电路等.本来都没信心了,您给了我鼓励,我想有机会再发些图片上去.再次谢谢!!

我制作此机是为了1.充分利用手里现有的元件发挥其作用.
                2.用于纯音乐欣赏.所以设计的输出功率不太大,2*14W.
                3.省去输出变压器,采用晶体管电流放大做输出级,也能保持前级电子管的音色.
                4.做袖珍机,元件按装采用覆铜电路板,为缩小整机尺寸创造了条件.
                5.追求音质,电子管的电流用的较大,第一级1MA,第二级3MA.(按曲线设计的).
                6.证实一下自己的制作能力.
                7.想听听各位老大各位烧友的看法.望多提意见.

六楼是放大电路图,十楼是电源电路图,不知neptune兄要看那些图?

不错！
声音如何！高音纤细么？

Re:普通的元件,不普通的音效.胆石混合式袖珍小功放.

回DarkHorse兄,由于本机没有大环路负反馈,所以瞬态还不错,用仪器测频率范围20Hz---80KHz比较平坦.主观听音也不错.
