我覺得焊入蘇位危險咗少少, 都係做係插頭會安全D。
我都咁諗，皆因我見過有個ching 隻老年咁大 0.47瓷管 jensen漏油了

yeah~,i did saw such kind of happening (on a Jxxxx cap), too !{:1_331:}
又學到嘢!{:6_193:}
我今天都入左粒玩下。
係有唔錯改善。但唔知點解用在膽機個音量會細左。
AV AMP就無呢個問題。
我都試左一款,感覺上音牆窄左.

見CHING 牆身係英式插, 拖版都係用美式嗎?
其實都想問下如果第時轉玩美式POWER CORD式係咪牆身插 ...
小弟全屋牆身都係英式插, 大力水嘢就用英頭直入牆, dac, cdt, bdp, tv等等就用美式拖版~~!! {:9_423:}

本來我都係諗住做粒丸仔插拖板, 後來上到源哥到, 佢話可以既話直接入牆又直接啲又慳返個頭~~!! 我諗每粒cap既質素未必一樣, 有次貨漏油都有可能既~~!! {:8_395:}

總之用Jensen小心d。。。需然它漏的油沒有什麼毒，聽聞都是工業用橄欖油。。。不過都怕漏電或跳fuse。
相同比較，外國的polypropylene， MKP 電容faulty 情況比較少。400V 630V 一般非常安全。（不要用大6貨）

<< abstracted below for ref. only>>
Sandia National Laboratories has developed a capacitor technology based upon impregnation of plastic film capacitor rolls with perfluorocarbon insulating liquids. Perfluorocarbon liquids are made from various hydrocarbon liquids through a complete exchange of the hydrogen atoms with fluorine atoms. The plastic films evaluated to date include polyester, polysulfone, polypropylene, polycarbonate, and polyimide. After in-depth evaluation of the perfluorocarbon impregnants in capacitor research, development, and recently in production, we conclude that they are highly effective materials for this application. No other single liquid displays their range of required properties. Perhaps their most valuable properties as impregnants are their low surface tensions (12 dyne/cm) coupled with low kinematic viscosities (0.4 cS). These result in void-free impregnation and wetting of the interior surfaces of plastic film rolls without need for such auxiliary measures as interleaved paper wicks. In research directed toward developing a long life, repetitive ive pulse, high reliability, and high energy density capacitor technology, another capability of these liquids has been demonstrated. If a low temperature perfluorocarbon arbon liquid is chosen, an evaporative coolant function will stabilize the system temperature below that which would cause thermal degradation of the critical electrical properteis of the plastic film dielectrics.

{:1_253:} 是，我也是在其他forum 看到。 以前有音響雜誌報道直情話訪問Jensen老闆佢自己親口講。不過記住系工業用。吾系煮送果d
