对寿命不利[em11][em11][em11]

文招

先把大三肯管固定在LM4780旁边（我用胶水固定的）再把管脚插入板上的二个固定洞焊上錫，我的板子现在很巩固，手拿板子提起散热器也没问题[em06]

文招

正规做板时拧散热器的地方一定要留多约1cm长。今天想到一个固定散热器的方法：<img src="attachments/dvbbs/2005-2/200529223734551.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/2005-2/200529223734551.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/2005-2/200529223757714.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/2005-2/200529223757714.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/2005-2/200529223819564.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/2005-2/200529223819564.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/2005-2/20052922385589.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/2005-2/20052922385589.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

0R47的电阻我用二个0R22的串联代替[em11][em11][em11]
我认为金属膜的比那些水泥仔好用[em06]

最边上的两只标有0.47的是电容！[em10][em10]

。并联接法，但低频强劲了很多。声音饱满有力。是事实。

但整体感觉总有些别扭[em11]

效果和版主差别不大，低频有力很多。
但是听久觉得声音没弹性，压抑感很大，耳朵很累。电阻都是经过精密配对，（误差0.1%以下）。

原因还没有找到，望大侠指引迷津！

很简单，用一个发光管串一个5K1的电阻并在继电器线圈上
