刚才试了一下电感前后的噪声
这是试验电感前的<img src="attachments/dvbbs/2004-12/200412715118952.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/2004-12/200412715118952.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

接电感前时,音量开到最大,基本耳朵贴近喇叭才有噪声,昨天听不出,不知是环境还是耳朵[em11][em11][em11]
接电感后时,音量开到最大,在20cM已经很明显。
有人说6Z4后的电容不能大于22uF,怕冲坏6Z4.我看论坛的板子就是这样考虑的。
我将22uF换成100uF的,(以前我试过用220uF也没见6Z4玩完)。觉得噪声有所改善。
