偶的LM4780的试验版也搭好了！

小钳子

用N块板子叠加而成

制作前，首先将论坛上几位前行者的帖子认真读了一遍，谢谢他们的努力可以使偶尽量少走弯路！

学习以后，偶决定对他们提出的以下几点问题特别注意：
1.印版上的LM4780的第19脚没有接地，需要跳线处理；
2.注意到文招兄的经验，没有接电源部分的二个旁路电容；
3.将反馈电阻的阻值修改为1K和20K；

实际制作完了以后，就是开始图片上的情形，因为手边的元件并不是太多，加上武汉这个地方实在找不到什么发烧元件，所以电源部分的二个100UF大电解电容随便就找了二个好像是什么黑金刚到电容搞了上去——后面偶将对这个处理作深刻检讨！

因为偶系初级菜鸟，因为系试验，所以选择了放在桌子底下，万一........@0@3%54
(桌子就没拍出来，菜鸟也需要些面子啊！)
<img src="attachments/dvbbs/2005-2/200522121329536.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\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-2/200522121329536.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

做炮灰试音的惠威书架箱
<img src="attachments/dvbbs/2005-2/200522121717152.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\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-2/200522121717152.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

最后调整了的板子
<img src="attachments/dvbbs/2005-2/200522121759189.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\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-2/200522121759189.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

豁出去了，最后试音的美之声战神30（自己做的，有点丑，不敢开闪光灯来拍！）
<img src="attachments/dvbbs/2005-2/200522121916297.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\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-2/200522121916297.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

太晚了，明天出试音报告[em11][em11][em11]
