[#55] etsang3 修理好聲"山水"機一部 hkmk 兄,多謝讚賞。 ttvfwong hing, ..factory at Kowloon Bay... yes. you may be right. Most of the time I will be at showroom and just sometimes I will go to ShamPoKong to visit the warehouse and also the TV (B&O) and HiFi service center there. I still remember another Master, Mr, Fung there. TRP also did professional acoustic system (PA amplifier and Recording Studio equipment). That's why I can get 2 16" Wharfedale woofer back home for DIY. They are spare of Lee Theater of that time. Those days were fun. While I was working there, I could only see the small and the tall TRP Sepctrum loudspeakers. |

[#62] etsang3 修理 Marantz 分享 Hi etsang3兄, 實在是一位難得的HIFi醫生, 本人從不懂電子為何物, 但真的喜歡一些年事已高的器材(補回少年時買不下來的遺憾), 但他們往往都有問題, 若本人像樓主一樣有這樣的維修奶O, 幸福不少 |

[#64] etsang3 修理 Marantz 分享 etsang3 兄 我有d個人心得唔知有無用, 如果舊膠開始硬化無咁有彈性, 又或者個裂口比較受力的話, 可以切一塊細少的樹膠片, 以混合膠補上去作為強化, 呢個方法甚至試過用係大眼乾衣機隻門個彈力扣都頂得順架. ![]() |

[#68] etsang3 修理 Marantz 分享 etsang3 si-fu, Just find that when playing a few particular CD's, my Sansui AU9900 gets some distortion (拆 聲) at high loudness level points. However, most of the time, it just sings sweetly and normally. I've checked, as you have suggested, that the amp is warm when idle for about 15min. Any idea what possibly causes the problem? |

[#70] etsang3 修理 Marantz 分享 211兄,師傅教我,膠爆左,要從新"啤過"先夠力喎。 嘩!做個公模"啤過"咩!"啤過"意思係從新溶化D膠使裂口再融合埋一齊,不過大爆口用辣雞辣得太耐一般妘ㄦ|縮,所以要加膠辣,要用雙同膠料(475,ABS)或可能要雙同顏色添,否則不能融埋一齊。辣完一舊舊就用苳M或沙紙做後期工作,手術高明,整完連裂過都睇唔到。 點知係乜膠料? 師傅教我燒(辣)膠料聞下,唔同膠料有自己獨特味道。 去邊度搵膠料? 我成日行街見到D塑膠垃圾,清潔,顏色特別,都會整碎帶些少返屋企,以備不時之需。(哈哈,正垃圾佬一名) |

[#71] etsang3 修理 Marantz 分享 SoundOfMusic hing. I think it is due to bad contact or aging inside the amp. There are Noise Problem fixing report on the web. There are so many parts need be replaced. Terrible. I have 2 power amps fixing now. If you still want me to help to repair and you can wait. Pls PM me la. Thanks. 換電容 http://amp8.com/sansui/au555-20000/jpeg/au990031l.jpg 換漏電原子粒 http://amp8.com/sansui/au555-20000/jpeg/au990031t.jpg (網站: http://amp8.com/sansui/au555-20000/au9900-4.htm) |
