我的板子就是<img src="attachments/dvbbs/2005-4/20054102095217.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/2005-4/20054102095217.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />这样子,不知是不是我带电焊接,现在不论怎么弄都没声啦,

我PCB板上23脚本来是和地接在一起的，为了接晶震，也被我割断了

我试验了四种情况：
23脚接地，不接晶震，正常
23脚接地，接晶震，几乎全是噪音
23脚接+5，不接晶震，没声音
23脚接+5，接晶震，有声音，女高音演唱有破音
（编辑了一下，刚才写错了）

你在检查一下线路吧

好老明

新版的线路好象和旧版不同,23和24是连在一起,我割开后把23接地并断开晶振电源后居然没声音了,救命呀

好老明

你的1543是怎么摩呀?能公开一下让我等学习么?

好老明

有没有人比较过8块和4块的区别呀?如果8块肯定比4块好的话,那个日本仔为什么不用8块呢?应该有它的道理吧?敬请DX指正

看看丽特8块1543的DAC,我现在是用sony 227esd＋这个dac
声音比227esd（没摩）要好，音场宽，演唱者的口形比用227esd要小。

拍得不好!~拿远了看不清,近了又模糊!

不是74的!我拍的是54LSC04DMQB,军用陶瓷的
我也用在DAC板子上,效果比一般的04差太远啦
你只要能找到陶瓷的就换了它吧
塑封的我觉得日立的不错

大家可以借鉴一下,呵呵...我也正准备弄1543...

不过我要建议那块74HC04最好用这种的，声音会更上一层楼！
