剛買了一部Marantz 8B,部樹寫明110V,但賣家已改220V
,想請問各位CHING,這有無問題,是否被大改,對火牛有無問題?

1. Marantz 8B的火牛是有一個大火牛蓋把所有火牛蓋着,基本上110V改220V如果繞得好,從安全角度並無問題。不過如果繞得唔好會出現火牛過熱或火牛起震等問題。重Re-sale Value角度翻繞火牛的器材Re-sale Value較低,也較難出售。

2. 110V轉220V已可以稱為大改。

3. 同1.

如果說翻繞電源牛完全無影響是騙你,不過影響一定沒有翻繞輸出牛那麼大吧了。

唔該Pilotrol,我剛剛至電賣家,佢講後期8B可以搭線位轉
220V,約我唔信,可以幫我轉返110V,這可信嗎?

若賣方無老點,就改番117v吧,費時你第時唔玩想放時要週圍找人把機還原。(*不過你都係問清楚Pilotrol大人有關舊馬八的版本疑問先啦)

其實從用家角度來說,能用低於市價價錢買台改了220v的美國機(改得妥當的話),也無不可。

我早兩年都平平地買了台改了做220v的老麥再生版275(機身寫住117v),當放台大力士係屋企「看門口」。

FYI, early version of Marantz 8B with TP5 power trans doesn't have tip for 110V/220V...! However, small amount of very late period Marantz 8B with TP5C power trans do have tip for 110V/220V.

Ah Ming has mentioned in the Audiophile that some later 8B could be converted into 234V. I have seen the same said in the 8B manual if remembered correctly.

you can check the transformer lead , Marantz 8B are use "West Electric Wire" (cotton coating), If it use plastic wire something like UL1015 grade.....99% rewinded.

Think twice before you act! If like what the seller & pilotrol said, your 8B is a 220v/110v convertible version, then plugging it to mains 220v directly leaving out the 220/110v step down power transformer will made your 8B sound much better due to lower output impedance from the mains & getting rid of the unnecessary magnetic/EMI interference from the step down tranny.

Since you already have an appointment with the seller, why not let him show you that it's a real TP5C convertible & learn how to re-tap the primary.

謝謝Derek2A3 CHing,賣家講只要在場等佢10分鐘就可轉回110V,我想信係TP5C,但係想知到110V好聲定220V好聲?

FYI, there is no difficulty to classified TP5C and TP5. Since TP5 only has two input power cable in colour of black, but TP5C has 4 input power cable in Black/Yellow, Black/White, Black/Red and Black colour.

謝謝Pilotrol,原來我部8B係TP5C,這樣是否需要轉回110V,我部機有非常非常輕微的烏聲,這是否220V所至,謝謝!
