    WP3露天應該找的到
    台南的佑昇(又昇)????樂器好像還有庫存
    可以查看看
    因為我也是在那網購來的冏

    有阿 看了一下 只有一個有賣 而且好像沒現貨了
    真不好意思 忘記標標點符號了
    我的意思是 用PSA-120接到TU2orNS2後
    在用roland的擴充線去接其他的效果器
    這樣會不會因為TU2 NS2並非正規電源供應器
    導致雜訊高

    重點在於變壓器，穩壓的方式....

    WP-4間諜照

    費盡千辛萬苦，搞到WP-4的間諜照。(還有零件沒弄上去)
    [​IMG]

    左邊一排是日本Panasonic的電容，右邊12個輸出座(3.5mm鍍金耳機座)，三種電壓輸出，其中12V還有18V各兩個輸出，每個輸出獨自採用一個穩壓電路。電源輸入採用6 Pin Mini DIN插座，體積與WP-3差不多大小。因為有三種電壓輸出(有雙電壓版)，所以變壓器也有三組電壓輸出，不同電壓之間是有隔離的。變壓器因為有三組次級，且電流都超過實際需求，壽命比較長，但體積相對很大，這是唯一要犧牲的地方。但相信這一切都是值得的。

    想問一下W大，所以電壓隔離是在變壓器上做的，還是在電路版上做的阿？ 我之前有問過有沒有9v加isolate的版本，W大好像說成本會很高，但看到前面文章有提到"雙電壓"和"三電壓版"，到時候可以選擇"9v/9v" or "9v/9v/18v" 的搭配嗎？ 我目前使用wp-3接delay的時候雜訊還是比單給delay一顆變壓器的時候大...如果有isolate的版本那就很棒了

    理論上是可以這樣做，但是可能沒有這必要。這樣子變壓器的規格又要改，數量少的話很不划算。雜音的問題大致上是來至於共用一個電源所產生的接地環路導致容易感染電磁干擾，所以建議大家無論如何，變壓器還有110V的東西都要盡量拿離效果器遠一點，能多遠就多遠!

    所以這次的WP-4是八個9V, 兩個12V, 兩個18V對嗎?
    請問各自提供多少安培呢?
    謝謝

    9V部分1000mA(變壓器1500mA)，12V部分各100mA(變壓器共500mA)，18V部分各100mA(變壓器共500mA)。基本上12V和18V的部份是由電阻設定輸出電壓，所以要改成9V也行，但相對穩壓元件消耗的熱量會比較高，所以不建議這樣做，每個設計環節都有仔細考量過了，希望在可以接受的價格和性能之間獲得最佳解決方案。

    WP-4

    WP-4看起來真不錯
    因為同時有要吃9V 12V 18V的效果器
    原本想買voodoo pedal power 2+
    看來有別的選擇了
    可以透露一下大概什麼時候上市跟價位嗎?
    謝謝

    加工廠的樣品遲遲不來，所以上市沒有確定的日期。
    售價方面應該是4.2K上下。雙電壓(9&18)約3.8K上下。
