| [#1] 擴音機volume掣 小弟有部好舊嘅擴音機 volume 扭至最少仍然有聲出 是不是volume 粒alps電位器到期 還是其他線路故障問題呢 現在困惑中 諗住換左粒alps後先再算 |

| [#2] 擴音機volume掣 C Hing, 先用電子清潔劑(油性)憤下個掣,不停轉下個掣,看下有否改善? |

| [#6] 擴音機volume掣 原廠舊机換 volume, 要計埋个旋钮,是收羅絲,狗牙定 d 型孔,有時仲要計埋條柄長度,有冇loudness 制?,有的話要買番同數值抽头的,当然要買番一樣阻抗的,如50kA型 , 100kA型。大细一樣的,如直銲底板,要計埋腳位最好。 最後修改時間: 2021-03-10 18:07:16 |

| [#9] 擴音機volume掣 #7 師兄; 請問用了電子清潔到洗volume掣會衰聲的理據是什麼?因為我之前都有用, |

| [#10] 擴音機volume掣 因為它的薄膜已受到電子清潔劑所沾染及或薄膜內的化學分子已被破壞或已改變,聲音的純淨及清析度已一去不否返了,要換個全新Volumn制至為最佳最好聲的方法 最後修改時間: 2021-03-15 00:06:17 |

| [#12] 擴音機volume掣 CRC contact cleaner has residue, not used in our Plant for many years. If contacts are accessible, including vacuum tube pins, simply use coarse type eraser.(not for carbon type volume control) Interesting, got a remote control volume with Soundwell motor with gear box. Gear worn out. 最後修改時間: 2021-03-15 08:44:25 |

| [#13] 擴音機volume掣 So ridiculous. I used many times for my gears, unless the VR is completely worn out then you need to have a new replacement. |

| [#15] 擴音機volume掣 #13 your comment is ridiculous and showing that you having limited knowledge. I am a professional working in industrial high voltage equipment up to 11kV You are only working on tube amp. at best. In govt, many guys are like you, failing to listen and just pretend. Not gaining experience at all. Many hkgers are merely little toads(not even frogs) inside a well. 最後修改時間: 2021-03-15 10:47:46 |

| [#16] 擴音機volume掣 看後忽然有所頓悟.... 我的頭髮,皮膚薄膜,已受到洗髮劑/沐浴露/肥皂...長年累月所沾染,表皮的化學分子已被破壞或已改變,靈魂的純淨及肉體清析度,已一去不復返了。要換個全新的驅殼,至可超脫成為人上人的方法。 |

| [#19] 擴音機volume掣 要造一台mose師兄的擴音機,從採礦煉鋼 ,晶體管內的矽提取,封裝polymer物料,油漆,電鍍..所用到的化學品還會少嗎?幾十年以來,音量掣內裡所積累的污染物還會少嗎?幾十年之後要延續它的壽命,打算清潔它,噴一點化學品,還算虧待了它嗎? 造紙要用上多少種化學品?我每天還用它來擦咀和擦屁股...我的天!!! |

| [#20] 擴音機volume掣 I dont mind using CRC cleaner if need to, considering the hassle of the alternatives. Usually, after spraying, sound indeed will get worse for a while. Just rub and turn the knob for a few days, sound will be ok again. (The cleaner does have residue but then it can be rubbed off after some turning, I guess.) Yet, if there is noise when turning, I usually save the hassle and just turn turn turn till noise disappear. CRC is my last resort before I really have to roll up my sleeve to replace. Yup, I am lazy as hell. |
