前级终于搞好了!!!
这个前级由我设计图发给钳子,再由鬼版修改制版,再试制。这样来来往往的,经历了半年有余,其中还引发了一些小风波,现在终于出声了这是正在测试中的前级:
专为这个电路而设计多重稳压电源,这可是前级靓声的保证哦

这个是为这个前级而专门制作的无氧铜环牛

这是输出热噪音:小于5mV

这是前级带1k负载,输入10kHz方波时的电源端的波形,可以看到基本无波动

我觉得还是音箱牛
JBL4425的大家伙可能现在已经停产了吧?那个号角高音的音质是一般液磁高音头没法比的特别感兴趣
不知搂主可否转让一套套件呢?喜欢
喜欢牛!
CWW兄请教:你的散热器尺寸是多少?静耗是多少?工作温度是多少?
我正在做一部后级,每声道散热器+沉热器已有30KG,也算是巨无霸了,可是和你相比。。。天外有天。。。。。。
牛牛牛牛
这个后级是今年做NB的了
我估计一时也没有能比这个大的了配服!!
500Khz的方波这样好!http://www.hifidiy.net/UploadFile/2005-12/20051228122758592.jpg
好啊
不错CWW兄!
没想到如此的大!自制的纯甲类后级内部。。。。。。
请看:http://www.hifidiy.net/dispbbs.asp?boardID=2&replyID=86349&ID=9013&skin=0哗!
楼主的后极好恐怖啊,这么大一个?还是单声道的。期待中
可否打开让我们欣赏内部。。。。。。<img src="attachments/dvbbs/2005-12/2005122813734289.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/2005-12/2005122813734289.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
自制的纯甲类后级
前级和后级线路图
前级和后级线路图 我用音箱和你一样你的后级机箱是哪里买的?多少钱?型号是??
你的后级机箱是哪里买的?多少钱?型号是??赞一个
线路是否和95年某期的无线电与电视中的前级电路类似?漂亮....
兄弟可否上线路图一看?谢了...有钱人,NB
是朋友在丽特买的,
他只用后级机箱,前级的箱子就送给了我!!以下是引用hifiaudio在2005-12-28 13:21:00的发言:
