咋天正和狂之又狂兄聊紧，邮递员就送单到了。
我还用摄像头照了一下邮递员给狂之又狂兄看，俾其也BS一下他[em11]

小电感我用DL6243测为1.48mH,大电感为3.51mH,还算正常吧？

我估计就是胆的高压和灯丝电压问题！
昨天，公司忙，没有试变压器屏蔽，晚上再试！

搞乜嘢PMD100啊<img src="attachments/dvbbs/2004-12/2004128115534537.gif" 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/2004-12/2004128115534537.gif\');}" onmousewheel="return imgzoom(this);" alt="" />

7220不过隐，我有只PMD100[em11][em11][em11]

不如加快SAA7220P/B数码滤波器玩下仲实际D啦!![em11][em11][em11]

变压器漏磁干扰电感!!!这才是罪魁祸首!!!!!!!!!!![em06][em06]

今晚又试在6N11灯丝中加入中点平衡电位器，先断开原滤波电容的接地点<img src="attachments/dvbbs/2004-12/2004127224353146.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/2004-12/2004127224353146.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
还真不舍得下刀[em11][em11][em11]
然后在6N11的4,5脚和地之间接入3WB100电位器
<img src="attachments/dvbbs/2004-12/200412722494143.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/2004-12/200412722494143.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
用心慢慢调整平衡点，收益不大[em10][em10][em10]

我看整流胆虽不致即死，命也许不长吧。既然这样改噪音会减少，不如改成稳压供电重更加好。

但我为了方便，没有加[em11]
再说5元一个的6Z4少说也能用一年吧[em11][em11]
