| [#25] etsang3-談修理問題 Tsang sir and all Ching, Need your advice. Last week, I took out my SP-9 from the HiFi rack and have a look inside the machine. I found that one end of the high voltage capacitor (100uF 450V) is as photo below (which look like cracks but not sure). Do I need to replace it? What type of capacitor should I get to keep the original sound? Thanks.  |

What type of capacitor should I get to keep the original sound? ---------------------------------------------- This question i asked Estang3 b4, i try to copy and paste his answer as following: 1. if they are good film caps, no need to replace. But must change all the ecaps which is 10+ years 2. Cap is Cap. Good Quality can be good for Audio and Power supply. A good power supply cap (fast charging, fast response, low ESR etc..) is higher quality than so called Audio cap (actually audio requirement is nothing) 3. go to SSP 街邊檔買d 105度的ecap 試試 following link is what i do: http://www.review33.com/avforum/forum_message.php?topic=55100428181821 hope this can help you 最後修改時間: 2011-04-17 09:53:45 |

| [#31] etsang3-談修理問題 roger457師兄. 不是想加大玩. 因小弟是初哥1名.在網上見到有2X.25uF 450 VDC的電容才有此壹問.照字面解就是兩倍.25uF.如果換在胆機用以取代.25uF將有咩後果。謝謝 |

| [#33] etsang3-談修理問題 X1, X2 & Y marked at the body of the capacitor certified its capability to be used at circuit connect to Mains Power (e.g. 220Vac in HK). A MKP X2 AC cap can be used in Mains as well as in Audio circuits (power supply or audio signal PCB.) Therefore X2 doesn't mean double the capacitance nor 2 cap inside one body. http://my.execpc.com/~endlr/line-filter.html |

| [#38] etsang3-談修理問題 - AU9500 曾sir 你好！我的9500 出現了問題！請問如要check在那裡呢？用speaker 不能出聲，但用耳機就無問題！ ======================================== 可能喇叭保護板出問題 http://i20.photobucket.com/albums/b206/etsang3/Sansui/AU9500/opencase.jpg 1.耳茼有聲是,喇叭黑線照常接機背黑色.喇叭紅線點下金屬點圖中3或4,睇下有無聲(有就一定係喇叭保護出問題),喇叭紅線接回機背 2.檢查FUSE 051,052,053有無燒 (有就換1A FUSE再試) 3.開電時,檢查喇叭保護relay有無"得"一聲,及看見佢動作 (無就換TR910,TR902先,都系唔郁就換埋Relay) http://i20.photobucket.com/albums/b206/etsang3/Sansui/AU9500/protection.jpg service manual ============ http://elektrotanya.com/sansui_au9500_sm.pdf/download.html |
