william己經跟你說了

為什麼你不去那邊,他們收了你錢一定辨好的.


不會是因為
KK-ho說
Unlike only "blowing" something.
你不好意思.


新手上堂certifiy to calling "金錢換取知識". 沒事的.我們全部人都明白那個道理.他們生意人也應該明白.一定解决得了.上堂時間不明白.那樣當然問老師,你不問他還可以問誰.
要是部功放有直流 出千万不要再用.有可能後面功放及喇叭死.


飛水線 :?:  :?:  :?:

ronaldc兄 ：問題解決了嗎？

will go to william's office try to fix it!(also try to improve)

Hi William Sir,

Just finish my SP10, but I got similar problem.

Can here noise (See ... See / Dee...Dee) around 4 inch away from the speaker.

Setting:
-SP10 + UcD180
-volumn position at 0
-without input source

Is this normal?

thanks,
Kenny

點解上了堂還會這樣.

你地上堂時有沒有聽老師講解每一部份作用為什麽要這樣.每一粒零件作用改變數值後會那麼.焊上前有沒有測試每粒誤差、配對、保證工作正常.


完成有沒有用驗測電壓電流.再用毫伏表.示波器.信號發生器.失真器.頻率特性器.頻譜分析器驗測.最後用耳朵.這麼是正確基楚DlY要求.





DlY 不代表段估.
