部M-one, 駁speaker left channel 會有時冇聲, 開頭開大聲少少會冇事, 而家都唔太work.
用headphone 就有D 沙聲,
見其他forum 講係D cap 有事~ 話audiolab d cap 好似雞雞地, 想問有冇師傅手勢好D? 同埋大約幾多錢?

Most commonly used cap. is Wima, red box appearance. Open up and take photos, have general idea first especially size and pin to pin distance. Replacement cap can be Mondrof but size would matter.

There are a few repairmen right here, check this out.

要換晒所有cap 唔難，要搵出邊粒漏才換先難。

如果換就一次過換晒喇~

＞＞＞同埋大約幾多錢?

你想好聲還是有聲？

Black gate 除時成千一粒

2200FK, 35v 叫到二千

你開蓋睇吓情況先。

有工具唔難。你要換好多粒，時間長。自己試吓做。

部機唔貴，你叫佢換BG電容？

Audionote 出名漏電是Jensen D銅膜銀膜油浸交連，間廠因這個問題早兩年摺埋，blackgate 好耐用，如非過熱乾塘理應十多年都不需換，建議check清楚或先換交連電容先.

audiolab M-one ...

係唔係呢部？

#4 如果換就一次過換晒喇~

粗略數下(下圖紅點標示)，眼見E-cap接近卅十粒，運工包料埋單隨時收您3-4千閒閒地，值得嘛？

換電容呢家野，除非打算自己郁手當玩下，拎呢部搵師父摩，唔多化算，係我就換機好過 ...

人工加零件，不如買過部算

其實真的不用換哂blackgate，需然我都有但現成抄價不值，而我九成機率可同你講問題可能主要是Jensen的交連電容，如果會直接會細聲好多就不建議再開機會出直流，另外就是有可能整流子出事，就來釘的整流子發熱後會漏電(燈絲整流或穩壓IC亦會), 現貼上台彎Look -T 師博的維修心得。

如果部機冇up grade 交連電容冇用Jensen油浸電容，而是ERO的綠色溥膜電容的話我可以話九成冇事，剛看過圖片和缐路，高壓和燈絲都是用橋式整流子，這種是低級貨式用十年八年就會壞好似你講有一邊聽聽下熱咗就細聲咗重有沙沙聲，曾幫朋友維修過一部同名的英國原子粒機都是相同情況，換了這些底級整流子就一天光晒，在鴨記找只需十元八塊錢一個！

多謝大家意見, 咁睇黎我買過部可能真係好D~

Audiolab, NOT Audionote Ah C-Hing

對不起了！可能我真攪錯牌子因已過十幾年，當年還是義務幫朋友不是扮friend收錢，已現在建樣樓主亦是，我不會幫你整收錢，因太簡單自己做不用五分錯搞掂，我相信都有九成幾會是整流子出事，就算換機整番都是二三十蚊，但二手價高好多，樓主自己諗！

看清楚了！

　要換的橋式整流！

Conclusion is buying a new one. The ones as marked on photo are namely electrolytic caps for power supply, no need to touch or replace by blackgate. Size would matter. Can't tell which are output coupling cap.(possibly the surface mounted round ones, nearer the output) very vulnerable to leakage. If it were Wima, red box, no need to replace, not bad at all, though cheap.

Double layer board, would need better skill/tool for DIY. Soldering at both sides.
