我的909版JLH耳放（参赛）

aeon

如果全用上909 的设计就更漂亮了，一直对909 的设计很佩服！！[em09]

1、照片有些模糊，对不住大家的法眼，只因为我的水平有限，器材落后。
2、以前在刚刚投入制作的时候曾经发过一个帖子：http://www.hifidiy.net/dispbbs.asp?boardID=2&replyID=89005&ID=9235&skin=0
3、这次在制作中，音频通道杜绝了小鬼子的产品，这也是我制作的初衷。
4、再一次严重感谢909版主，是他给了我莫大的帮助！！！

这个耳放的核心部分是909兄支援的，并联电源板、保护板是从牛哥（http://www.ngtop.com/）处购买的，只是调节了一下恒流电流及电压。换下了几对小鬼子的电容。

内部

在原来安装整流、滤波、稳压的地方，我用了一块从牛哥处购买的保护板
<img src="attachments/dvbbs/2005-10/20051027841478.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/2005-10/20051027841478.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
电源板也是从牛哥处购买的并联稳压板，换了三对滤波电容，环牛是从网友处买的双18V100W进口环牛（？）
<img src="attachments/dvbbs/2005-10/2005102784537118.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/2005-10/2005102784537118.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
电位器是从原音买的步进型的，自己焊的，有些丑陋，哈哈
<img src="attachments/dvbbs/2005-10/2005102784736286.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/2005-10/2005102784736286.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

SOLEN的耦合对高频的削减是很明显的。
