| [#3] 電反箱問題 以我理解是兩腳電源線L-N對掉了? |

| [#4] 電反箱問題 yes 反相, 兩腳電源線L-N對掉 |

| [#6] 電反箱問題 In general, L & N reversed is not the problem. The fuse protection is still exist. However, phase reversed on the mains plug of your equipment most likely can be heard fom the speakers. Always keep the L & N in phase is highly recommended to obtain a better sound stage. 最後修改時間: 2011-04-05 00:58:19 |

| [#7] 電反箱問題 吾知DC有無反相呢? 之前玩DAC加個正外置電源,好似將兩隻7805/7905對換了位置,聲是有仲比正常好聲又厚聲好多!但換來了超熱~加個大散熱先頂得住....有無CHING知點解? |

| [#8] 電反箱問題 Impossible, 7805 and 7905 cannot be exchanged. 7805 is + out whilst 7905 is - out. They have different pins configurations. So the circuit should not work at all. |

| [#10] 電反箱問題 254MM HING~ 我看清楚原來是TIP41/TIP42焊錯了.因之前問過其它老燒為何出到好聲也解釋吾到....就係甘先奇!哈哈 |

| [#12] 電反箱問題 254mm hing, 就係甘對換左再隻位置,Output 加到19v,谷行左粒2604成幾個月,去到極限音色過後就升天了,聲音到現在也不能忘記~ ^_^ |

| [#13] 電反箱問題 據我所知.交流電是由L(火線)走去N(回路).一秒來回50-60次. 如果調轉.是有危險. 如果是DC(直流電).調轉正負.那一定唔得. 如果講錯.請見諒! |

| [#14] 電反箱問題 No, you're wrong. Alternative current is no + or -. It is only referred to positive cycle and negative cycle. Direct current has +Vcc and -Vcc that it should not be reversed. Think about 2-prong plug on some 100 volts Hi-fi equipment the plug cab be reversed. 最後修改時間: 2011-04-06 20:13:00 |

| [#19] 電反箱問題 其實, 大半年前, 小弟喺度發起, 9 up 過一条 thread " 電源係音色之母"。也提過反相問題; 如果 "架生 gear"本身己经系反相, 但你供電又系正相既話, 咁你套嘢就系反咗相, 唔會太好聲。至於點樣 check 架生系咪反咗相, 系条 thread 度我己講得好清楚, 改善辦法就系將电源線 (或墙蘇)既 L 同 N 調轉駁, 小弟亦做咗實驗, L & N 調轉駁(確定 gear 系反咗相後), 完全沒事, 而且改善明顯, 匪夷所思, 目瞪口呆! 當時小弟不勝自喜, 稔住同人分享吓發起條 thread, 點知俾人插到飛起, 話不可信, 話講唔通云云, 唉! 鬼唔知 AC 電分L, N, E, 50Hz 咩! 如果常理可以解釋, 鬼要用貴電源線咩. 系度分享有獎咩? |
