各位兄台
江湖救急,请帮忙,我等着通电呢短接应该效果更好吧!
是这个道理,不短接的话是用1543内部时钟
但加电上机前有一个问题
SW4开关我没有,请问各位DX,能这样短接吗?能的话,这样可是在用板上的时钟?如果SW4不装上,也不连线,全部开路状态又如何?

不是两帖
是三贴啦,呵呵暂时只找到这个变压品器试机
双18V+双9V的,先用上罢。找到好的再换<img src="attachments/dvbbs/2005-8/2005814111844148.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/2005-8/2005814111844148.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
输出电容用两只有极性的一正一反也可以的
有心思还可在二个电容的连接点加偏置电压试下论坛的BUG,怎么发了两帖呀?
那样串联就是无级电容了,马兰士经常这样做。

输出电容如果用两只有极性的一正一反可以吗?文招兄焊得很漂亮!
我也是刚刚收到这套05纪念版的1543DAC,本来早就到了,可是又刮风又下雨的,一直过不去拿,也是今天才拿到,一看文招兄的已经快出声了!呵呵!你的调整电压的方法很有用!我就不用再实验了!照着你的抄就OK 了!
晚些有空做完我也上来讨论!呵呵
文兄,天那水有毒,少用为妙呀
文胸大或许受欢迎,HIFI发烧却最忌焊屎大督!
用天拿水不好的原因是它有可能对一些零件有损,
酒精清洗后留下灰白色的东西可以用硬尼龙扫子刷去。它的最大优点是对元件没有腐蚀性,不会损坏零件。哈
看来,老大们都爱面子,焊了板子还给美容,呵呵wongkm33兄
我认为还是天那水好用,只是我这次买的这瓶不好罢了。现在我用的清洗过后会留下许多水珠,说明不纯。以前用过酒精,洗后会在板上留下白色的溶解物
