[#1] etsang3 - 摩cheap SONY DVP-PR50P DVD SONY DVP-PR50P,有網友話好平,聲也不差,我個多月前起百X匯,$380買左,用黎整機粗用,的確無怪聲,無渲染。不過都覺得D聲係平面D,音樂感都唔係好夠。有朋友都買左,亦有同感,想我"摩"下佢,睇下有無得改善。佢係surface mount parts,摩機好哂眼神,我又忙又無mood摩,一聽就個幾月,今晚有mood到,郁佢啦! 有無兄弟都買左呀? 覺得D聲點呀?		etsang3 正式會員 218.xxx.xxx.166	2009-07-29 03:18

一體化底板都十分簡潔。

我最唔鐘意D機拖住條電源線,所以"摩"左做"8字"座。
用IEC又未免heavy左D。

摩主板如下:
1. 10uf 輸出交連電容覺得太細, 同埋係有極性唔好聲,換22uF無極性。
2. cheap NJM4558聲音呆板,換上Analog Device OP285 (sample),腳距唔岩,改到我暈。用鍾表師傅放大鏡焊到我眼濕濕。

3. 再起OPAMP底加上SIEMEN退交連電容,佢又細,退交連效果又十分好。

結果:
1. 高、中、低都伸延左
2. 聲音出得好自然,控制得好好,MUSICAL哂勒。
(我用蔡琴"民歌"試音,聽左多次,肯定左有改善。)

"用鍾表師傅放大鏡焊到我眼濕濕。"........

that's the biggest drawback of surface mount PCB. Easy to fail also!

OP285 and 4558 級數爭好遠, OP285 Precision Hi-Fi special for Audio grade IC. 4558 is just cheap ordinary IC

take a look at the back side there are optical port, I do not think this is a DVD player with digital input! So it must have digital out LA!!!!!!

if there is an optical digital out, then you can easily change it to coaxial out

But sometimes you may find it is inconvenient of not having a display

Changing the brightness to maxi of my mon and counting the RCAs at the back, yes, there are already coaxial Digital output just next to the optical port.
All in all I think this one is best buy but not any one can mod it as high hand had done in this thread!!

"But sometimes you may find it is inconvenient of not having a display "

254mm 兄所言甚是呢。佢有時起動比較慢,無DISPLAY, 撳左PLAY掣無反應都唔知佢"食唔食到"。

etsang3兄:摩改這位置的兩粒並不是50v10uf電容,而是16v47u電容,是不是看錯了.
