看到內部的線路後,發現有灰色膠包着的訊號線,把三條線干於新的RCA socket上,有聲出,但只是前級扭小小,已非常大聲,而且還有唔唔聲添,不知有沒有方法解决大聲及唔唔聲的problems.
小弟是新手,希望高人指點。 謝謝!作者: kk_ho 時間: 2008-11-14 09:04 標題: Re: 想請教: 合拼amp 可否改成後級amp呢? yes, it can
from your photo
left hand bottom side : input,
left hand top side, volume control.
At the middle area, found some op-amp buffer (SIP-9 package may be)
Skip the volume and input buffer. Then feed the signal after the op-amp, that is
Most have 1 capacitor coupling between opamp and power amp stage.
Remove it and feed into is simple作者: ckfok 時間: 2008-11-14 13:34
多謝師兄指教,但甚麽是"opamp", (小弟是超新手),煩師兄指教。作者: ckfok 時間: 2008-11-14 13:39
還有師兄提到需拆去的是"opamp" or "capacitor"?
