楼主是昆明哪的 有机会聊聊?
以下是引用aide在2005-9-21 10:50:00的发言:
最近经常看见有朋友介绍GC功放的制作,再加上原有的一台天逸功放因为底噪太大被人打击没有透明度,于是想到了做一个GC功放。线路图参考了坛子里的LM3886的图,但是稍微修改了一下。
<img src="attachments/dvbbs/2005-9/200592110376167.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/2005-9/200592110376167.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
开始做的时候一直很头痛机箱的问题,因为自己做不太方便,昆明也没有哪里卖合适的机箱。找来找去,还是只好去圆西路代理丽特的JS那里买了一个A28前级机箱,然后拿回来用电钻按需打孔。
具体的布局如下:
<img src="attachments/dvbbs/2005-9/200592110412802.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/2005-9/200592110412802.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
电源入口插座是从电脑电源上拆下来的,质量还可以,然后在张官营旧货市场刨了一个TDK的滤波器,下面的图就是滤波器和旁边的扬保。
<img src="attachments/dvbbs/2005-9/2005921104456516.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/2005-9/2005921104456516.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
在接下来是主区域,用四个飞利浦15000uf的水潭,上面并0.1的钽容,两片3886用螺丝上在散热片上。用屏蔽镀银线连接到音源切换板。音量电位器装在音源切换板上,用延长杆延长控制。
<img src="attachments/dvbbs/2005-9/2005921104858264.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/2005-9/2005921104858264.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /> |
