星期日下午有些少時間DIY了一套之前係淘寶買的47耳擴
套件一套

底板一塊,47耳擴要既零件唔係太多

賣家一早分好曬電阻,不過自己都度一次以免攪錯

仲有一埋插座同電容

上零件次序,由細到大
先上電阻

之後上Opamp座,要留意U型方向

再上電容,小電容係無極電容,大水塘電容就要分正負喇{:6_142:}

過程同樂趣先是重點啊{:1_351:} DIY47耳擴過程{:6_193:} 師兄, 請問效果如何? 可以PM淘寶link給我嗎? 謝謝 motorbikeracer 發表於 2014-2-19 03:19 static/image/common/back.gif

套件本身跟兩粒OPAMP係5532,底音勁不過蒙
自己換其他OPAMP會好聲D

原兇未必係粒5532, 旁邊的零件值更重要, 有冇線路圖?
可改變電容電阻值來 fine tune 的.
同埋粒 op-amp 只畀 ±9V, 粒 op-amp 未能發揮, 最好畀 ±12V~15V.
畀高D電壓, 粒 op-amp 暖曖地重好聲.

套kit virtual ground 配備25V caps, 可用 +/- 15v 推。
各位師兄指教下應該點樣mod呢?
