有没有人研究过用什么电阻最好？反正只有两个，贵一些的也能用得起

两片说不定烧了几百米！

已经恨满意。
电容，特别是8214 的LPF端接 的电容，对声音的影响也恨大。
曾经试过33欧的电阻，噪音相对来说大了点，输出的电平也低了恨多，但低频恨爽呢。

电阻，电容试过不少。以下的是个人认为所试过之中最好的。
可惜很难寻觅到合适的数值。这几只也是绝无仅有。[em11]<img src="attachments/dvbbs/2005-2/2005220175227911.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/2005-2/2005220175227911.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

[em11]主要是用过工业品CBB做滤波

可惜体积太大装不下[em00]



Jensen银膜就买不起了。[em08]

[em11]要是胆机部分用点Jensen银膜，RMG碳阻更毒了[em11][em09]

高压滤波电容实在不好找。牌子好一点的拆板电容都被JS炒得巨贵，体积太大的又放不下，只好暂时用上这些，整流后依次为10U,47U,100U,220U.最后一只用到220U 不知会不会大了点。对胆电路实在是太菜。

阴极电容试了不少电容。
反而觉得这只普普通通的尼康6.3V/470U 最合口味[em06]呵呵。文招别笑我[em11]<img src="attachments/dvbbs/2005-3/200532153440188.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/2005-3/200532153440188.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/2005-3/200532153453965.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/2005-3/200532153453965.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/2005-3/20053215355674.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/2005-3/20053215355674.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/2005-3/200532153516992.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/2005-3/200532153516992.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

看大小，好象是一样容量的，是否内部有什么玄机。

这14个电容不惜成本的终极解决方案是什么，MIT<I></I> RTX<I></I> /JENSEN/REL<I></I> TFT。。。。。。。

470PF的电容好象没有什么高级产品可选呀。

这个S2比较正点呀，冲过去拆。

wongkm33兄听了之后再说，如果个人感觉有提高就值了，不要管别人怎么说。不就图个乐吗？

有点疑问，为什么都是11264<I></I> 9713，难道就只有这一周有S2出产，又偏偏以前什么时候也不出产，占尽天时地利人和，一周生产的都是超级酷的优质产品，S2可能是百里挑一，那么多其他的9713都去了哪里，或者是PHILIPS。。。。。
要不就是台湾的生产水平真的是太高了，也或者是大陆。。。。。。
看来只有真正有人来测试一下才能说明了。
