請鉗版不鄙進來拍塊磚吧！

訂下的制作要求是：
體積盡量少，
訊號通道盡量短，
一點接地，

基本上都能實踐，除了電源及輸入地，其他一律沒加額外導線。接地點花了最多時間構思，噪音水平可以說OK啦。

但仍有一個問題，開關機時的“噗噗”聲比較大，壇上的3875用同一套供電並沒這問題，不知何故。請大大們指教呵！[em02][em02]

唯有逐個上吧

基本上跟大伙所說差不多，我手頭只有一只30VA的方牛，動態及低頻是沒了。噪音很少，高中分析力也不錯，就價格來說肯定是超值的，遲些給它換個好一點的牛再看看如何。但問題是我想成品盡量小，給電腦或MP3等用途，很難兩全。

这样搭棚做1875还是第一次看见,花费了不少心思吧?

用了個P3散熱

來個近攝

再來

建議你另開一帖詳細說明情況，最好附圖，這裡的版主大蝦們是非常熱心的

回32及36樓，電路是國半DATASHEET裡的標淮電路，除了電源退耦電解外，其餘元件值都沒改動。電路翻一下帖子就有，真的找不到再PM我。

楼主是用哪个线路图呢？
给我贴一下好吗？

看得出花了很多心思，佩服。
