Dear Eric,

Thanks for the photos! Have you connected the isolation transformer to your A/V system?

Re: 隔離牛

[quote:901f6075e7="9.9N銅"]Are my 隔離牛 work properly..???? it show 236V ..?? so the a/c supply in my building is 230V..?? right. Modi ???? pls chk chk.[/quote]

It is possible to see voltage reading higher than 220 V. For instance, HK Electric Co. provides 220V +/- 6% under normal condition. If our meter shows 207 ~ 233 V, it is okay. Do you have another meter (DVM) to counter check your isolation transformer's meter?
