See the reply from me (mgattmch), this will answer your question re 220V to 110V step down transformer. You can purchase step down transformers from this site:

I'm guessing you have other components that you'll be taking that will also run off of 120vac? You will need to determine the total wattage of all equipment before purchasing a transformer. You may want to have multiple transformers, but that will get costly. Good links provided above. Some comments on AG are from people that have no clue, but some understand that it's not difficult. My personal suggestion is about double the power consumption of the receiver, which is 550 watts at 110-120vac, I believe.

Hi Fiesta and mgattmch

Fortunately my PC PSU and monitor are both 110 - 240V, my TV MIGHT be ok, still checking it out, and that's all my electronics really.

Being risk adverse, I think I'd rather give the receiver its own dedicated transformer, then possibly complicate things by having a transformer supply more then one device, especially I might get away with only needing the one.

The issue for me is that there is inexpensive and expensive transformers, and I sure they massively fluctuate in quality. I want to make sure my receiver and speakers are supplied with correct consistent power.

Thanks for your replies.

How to best calculate watts?

My receiver is a very solid 125w, powering 2X 4 ohm AR10 speakers.

Is it better to overpower watts, or match as closely as possible to max requirement?
