本帖最後由 sugargar 於 2010-6-17 20:05 編輯

As my Chinese typing was not good, will use English to share this modification on my Pioneer 51FD.

As I've limited budget for this modification (Under $1500), only used 5 Blackgate caps and use Nichicon KZ and Elna Silmic II , my modification divided into 3 parts:

1) Change capacitor ,resistors , fuse and IEC socket
Capacitors changed:   Nippon 180uf 400V>>>Nichicon KX 220uf400V
                                  1000uf & 1200uf x 4 >>> Blackgate Standard 2200uf
                                  680uf >>> Blackgate 680uf
                                  All other value caps   >>> Nichicon KZ and Elna Silmic II
                                  0.1uf 250v caps near fusex 2>>>Black Wima 0.1uf400v x 2

Resistors changed:original resistor>>>東京光陰 resistor x 3

Fuse changed:original fuse >>> 古河老白金 IEC socket and fuse

Wire from IEC socket to power board:original copper wire >>> 純銀線



2) Change capacitors in DAC board
Capacitors changed: Non-polar 47uf caps near 5532OPA x 8>>> Nichicon BP (Green) 47uf
                                 All other caps >>> Elna Silmic II & Nichicon KZ



3) Change original Panasonic 256MB SD card to Scandisk 2G SD card



經改造後畫面清柝度提升, 以前看不到的衣服紋理現在也清楚看到{:1_254:}
畫面的光度與黑位比以前更亮及更深沉
聲音方面比以前聽多很多細節位, 音牆廣濶了, 低頻比以前有力, 一改Pioneer 51FD 只有清柝度而欠缺力量的弱點
After changed SD Card can save 40% loading time(PS3 still the fastest !!)

After few days of testing, have done the final adjustment on the audio Non-polar cap.This really bring the machine to another stage (20% more on the clarity of sound), all Ching can guest what cap I have changed from the photos.

Actually I want to upgrade the OPA x 12 pcs. from 5532 to 2604but I'm not professional enough to change it, the soldering is too difficult as many tiny IC surround the OPA and not worth to take the risk.{:6_194:}
