- #87 [rickyp], 23-02-10 04:12Fuse 爆裂咁勁?
因為搬走時,太多嘢兼顧, 無諗過英國唔係220V.
唯有當去旅行咁去帶部機去整. 問過代理, 佢哋無其他推薦. -

The mains voltage from a typical UK home socket is 240V. Sometimes it can even go up to 245V as I have measured my sockets from time to time. Therefore it would be a bit risky to plug in a high wattage equipment, typically a power amp designed for 220V.
The voltage harmonisation was a thing when UK was still a member of the EU. By then a number of EU country e,g. Germany had 220V mains voltage where as UK had 240V. No one country was willing to alter its own mains voltage as it would be very costly and of little investment value. The final solution was for all countries to agree to a common nominal voltage 230V with some tolerance to be factored in when manufacturers designing home appliances. However when it comes to HiFi audio, our ear will tell us accurate voltage is acute to listening experience. In short UK voltage has not changed over the years, still 240V from the mains.
Before I moved to the UK, I sent my 220V tube power amp to the dealer to change the input voltage to 240V (generally for use in the UK and Australia). For the pre-amp, I checked with the manufacturer who said that it was good for 220-240V, so I did not ask my dealer to do the same.
I also had a bad experience with the UK mains voltage to share. I have a Japanese version 100V YAMAHA CA-2000 coupled with a 220V to 100V step-down transformer. It worked fine in Hong Kong. When I set up the same in the UK the first time, all the fuses on the YAMAHA power supply board got blown (fuse glass cracked). It is because the 240V mains voltage went through the step down transformer to become 130V and turned out to be much higher than the amplifier would need. A lesson learned..
So my advice is to get a step down transformer from 240v to 220v for your tube amp.

所以佢應該知道部機咩料.
至於部機問題原因都無解釋就耍咗比其他維修公司.
宜家先電郵問吓整機嘅會點先.
唯有勸告大家, 移民時唔好忘記音響問題. - #83 [Kenny], 23-01-26 13:32可能要考慮埋乜七都唔做。
膽機如果係多啲電壓，係咪只有隻胆光啲聲音大啲？間中燒灰士？如果唔係住喺郊區，我會試吓拖板都費事換。換粒大rating ceramic fuse，紐細一格音量照聽，最多密啲換胆。
但係廠web site faq 講美國版110V 同日木版 100V好多人問佢，佢話冇serial # 唔答…. 咁多人問，可能有事，所以最好都係問吓。

移民最好玩盡當地平野丶正如在美國丶玩老墨！ - #81 [phil.ng], 23-01-26 13:07>>> 可能要問吓有無得整同價錢,先至決定到點做.
正確丶訂隻牛原廠牛及人工．如要訂牛丶連人工通常機價一半！
買過部或轉玩二手 Naim - #80 [Kenny], 23-01-26 12:50係好消息！咁請問代理有冇答到英國機同香港220V機有冇唔同，需要改乜嘢？
有冇可能英國代理都冇收到日本廠答覆，所以交比其他師傅搞？
最好call 吓香港代理問吓？日本廠可以好stubborn，以為係水貨問題，一律唔答。
如果廠方代理都唔答，自己又擔心再爆灰士，一係買隻有filter 拖板just in case 你啲電唔係咁穩定，一係搵隻電子牛出220V。拖板可以考慮用RS Pro part # 455-321。

經過一輛電郵聯絡之後, 佢話因為唔得閒, 所以比咗個專做音響維修嘅公司, 叫PANDA SOUND公司, 位於lichfield .

車程要二個零九個字.

Countdown 7日後再打電話去問吓。
最好send 相有220V + serial # + 購買單據再問。省略係電話再認證一次。
最後修改時間: 2023-01-16 11:43:56 - #77 [rickyp], 23-01-16 06:45英國人打工都幾舒適, 星期五問咗, 負責人放假, 要下星期至返工, 寄出嘅電郵佢收到.
睇嚟要等多一個星期先至有消息.
買過部都係好提議, 不過呢一二年應該番唔到香港. - #76 [phil.ng], 23-01-12 09:21有要求丶買過部丶這 220v 的下次帶回港丶放二手
- #75 [LaLaLam], 23-01-12 07:37#74, 呢個叫 mains variac, 係玩vintage 膽機煲機必備的玩意，呢類膽機長時間不開機，是需要將電壓慢慢升高，令接近失效的電容器，慢慢重新建立電解層，但這種 variac係用擰炭刷的方法去調壓，會將牛短路一兩個圈，所以本身會產生噪音，並不適合平時聽歌之用。
