潛水半年，第一個作品(1875搭焊)，請各大大拍磚！

danielkwok

半年前偶然發現這綱，壇上的套件也買了幾個，1543-05，3875，小前級等。但DIY基本功有限，只在學校時學過一丁點電子，就只曉得什麼叫電阻呀，電容呀等，線路及實作可以說是一無所知。潛水半年，學到了到很多，到今年初終於動手做套件，有幸最終都能成功，然後當然是不能自拔，決心做個自發的試試，買了幾個1875，夠便宜，最適宜作炮灰，結果又是低級錯誤，其中一路居然搭錯正負電源，一個1875報銷。先上圖，請多多指正。

用了個P3散熱

來個近攝

再來

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?

唯有逐個上吧

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]

請鉗版不鄙進來拍塊磚吧！

能搞成这个样就不是新手了..工整而且线路也理得顺畅...好.....
1875我没玩过..不知道开机 的扑声是不是你的工艺问题...

四桶水

是开机的冲击电流声，加个延迟保护板就可以了

老兄搞工程大有前途啊！[em08]

嘿嘿，只是可怜了那只散热器，带一只1875天热都受不了的。好在是冬天！
