说明：做该机是为了给电脑用，

图说：机箱用网上买来的旧铝盒。
1：先将所有的孔打好，然后把孔边的毛刺去除。
2：用砂纸（依次为100号铁砂/600号铁砂/1000号水 砂/2000号水砂
3：清洗干净后凉干。
4：用散光银色自喷漆喷（我是每隔3-5分钟喷一遍共5次）。

说明:前级管我试过12AX7/12AU7/12TA7,声音还是12AX7最好,用12AX7时的电压还没量(万用表在单位)<img src="attachments/dvbbs/2005-2/2005215193052162.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/2005-2/2005215193052162.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
上图是今晚我用电缆里面剥出的线把机器里的走线扎好后的图片(仿古做法,呵呵!!!)<img src="attachments/dvbbs/2005-2/200521519334747.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/2005-2/200521519334747.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
请看扎线的特写,

我实际用的是12AU7推6P6P,12AU7阴极电压3.8V(3.8MA)6P6P阴极电压10V(29.3MA),

图说,这是完工后的内部图片,

这是放大部分图片,电阻和电容脚都用特富龙镀银线剥下的外皮套好后焊接,

这是电源部分图片,图上用黑线画的是接地线.实际测试输出嘈音小于1MV(我是用数字表交流200MV档测的).

主要材料：丹麦JENSEN的双C型电源变压器（输入220V，输出260V65MA/6。3V1。2A/14V1。4A（未用））丹麦JENSEN的电感8H/100MA，丹麦JENSEN的电容（100U+100U/450-500V），旧装国产双C型输出牛（5K：4欧）

里面的布局先从地线开始，地线利用小九脚座的中心焊脚和电容（JENSEN100U+100U/450-500V）的负极及一个喇叭座，用镀银线去外皮，再利用二个6P6P座不用的脚加固！！！

图二是主要元件装好后的顶视图，
特别说明：中间黑色的是用拆自丹麦BK仪的铝盒打磨后喷黑色自喷漆（3遍），里面装了二个国产的双C型输出牛（5K/4欧），以后打算用拆机的西电铁芯（舌宽19MM叠厚25MM）自己绕，<img src="attachments/dvbbs/2005-2/2005213141127839.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/2005-2/2005213141127839.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
这是后视图，有个小小的遗憾：因为我是先打输出和输入孔，等到打电源座孔时才发现宽度不够了，所以电源座只能斜着装了！！！<img src="attachments/dvbbs/2005-2/2005213141418171.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/2005-2/2005213141418171.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
说明：请看电感的接线部位！！用了二个黑色的塑料管（拆自5MM的压接头后面的护套）已防电。<img src="attachments/dvbbs/2005-2/2005213141717949.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/2005-2/2005213141717949.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

    做工不太好

jojo-pro

用料是很烧,可那个电位器真对不起这台机子,电位器是一个很关健的部位

用料发烧，手工差点，呵呵，实话实说楼主莫怪
