diyaudio上来的3886电路。

burderly

电流反馈的声音确实要好听得多

pK

据然出钱买成品板当然要设计成熟的东东

慢慢弄，不急

修改电源借口部分（参考原来的那个PCB修理修理）

两个声道都设计在壹块板板上（走线最好能左右对称）

决定开版了吗？定一套。

charlle

几天没有上来, 很高兴看到有这么多朋友感兴趣, 提供我做的Protel DXP 2004 工程文件给各位烧友参考. 包括sch,pcb和封装库.

weizinou

好了 我也要啊！！！

muhanny

慢点弄.做的好点,我也要!~

longhorn

我强烈支持开版！！！！！！！！！我一定要！
还有就是哪位大侠可以帮忙找这IC.LM318N,找了好久都不是国半出的。

大家热情这摸高,还没人制板,你应该出来了,如果真的好声,你该组织套件啊[em09][em09][em09]

请讲详细点啊。[em12]

整流管位置够的话最好能用MUR75X之类的，可选余地大些。扁桥好的难找。。。。[em11][em11][em11]

看不到charlle兄的设计，不过支持lsssun兄一下。我要一套先装，多少钱我打款给你。

请xrooo兄报价,先打样十套,送五套给坛内兄弟试装,并请提供试装报告

最后修订的PCB板是什么模样滴？十套少了，搞二十套先，赫赫

对电路作了以下修改：
More main caps.
Bigger input cap (now you can use more exotic caps)
Regulated power supply for the LM318
Bipolar feedback
Discrete diodes for rectifier
LM318 Biasing option (might change this to ccs)

RUDI的改版布局不错，但工程结构考虑不周，焊接完成后安装散热片会很麻烦的。象下图的滤波电容分开了一点，安装就会很方便了。

charlle兄啊！这板是你做的吗？不错嘛！还有PCB吗？还有就是看RUDI的板，LM318的4脚和6脚有一个33K电阻。可电路上没有啊！
