咁即係你都唔知自己用緊嗰啲係咩電線？

知！只不過要搬晒出來睇啫，要一點時間。
你部旦機用咗幾多年啊？

部旦機用左一年多D,有關係咩？
牆蘇改左做毒辣電未

未呀！牆蘇只有二個，一個插美，一個插英拖板。
查實係咪部機有啲問題,理論上就算用實惠拖板都唔會部機越唱越細聲,最多唔好聲啫 ...

初頭以爲部809散熱出問題，但部旦機都一樣，尤其聴到高潮位時，唱唱下就細聲左好冇隱

809同部旦機都一樣係咁嘅情況？{:6_198:}
越唱越細聲，意思即係當首歌播到高位時，原本好地地，但無啦啦就好似冇力吟！我覺得好似低咗幾個db，

abnormal. Perhaps some technical problems in some of your machine. You may check whether it is due to your tube amp or av amp by testing them separately. You may try to test the tube amp first.
但我試過獨立測試！發現部旦機冇吟嚴重，但部809就嚴重d
回復 18# aacc
I guess it is due to equipment issue not power supply. BTW, does your 809 has "peak cap" i.e. when the amp detects a large electric current (e.g. very loud noise) that reaches its max handling capability, the amp will automatically protect the machine by turning down the volume.
咁有無蚊左十仔插其中一部去另一邊試吓,咁兩個牆插到電箱係同一個位定分開兩個位。
