Recently I bought an Amiga bundle that included an Amiga 1000 and a 1070 monitor. Both the 1000 and 1070 are US models, meaning they need 120V at 60Hz. I live in Australia where 240V at 50Hz is used (technically, it's 230V +10% /-6% but the grid is commonly supplied with 240V since it is within tolerance).
With the bundle I also got a transformer to take the mains down to 120V. The owner said he hadn't used it for years. I don't have the proper lead so I'm unable to test the transformer (will it still work?). And besides, it's big and heavy so I'd like to find something smaller and lighter. Problem with these 2:1 transformers is that they have the same frequency on the primary and the secondary side. If I want something that can change frequency I have to pay a fortune.
My question is, how will the Amiga 1000 and the 1070 monitor react if I feed it with 50Hz AC (at 120V)? Will it affect anything? I think the computer might be ok since internally, it's just DC. But what about the monitor? Does it use the 60Hz as some kind of sync or anything? And can I use the 1070 with an Amiga 500?

It's a yes and yes in both questions! Where i live, we've 220v 50hz.
My A1000 (NTSC) and 1080 (NTSC) are both working great.
A step-down transformer is all you need. It's appliances like alarm clocks that don't work properly with the 60hz to 50hz difference. They work alright, but tend to miss the timing..
As about the 1070, yes, as long as it's RGB (which it is), you can plug it to any Amiga you want.

All these years I never heard of a 1070 monitor. Wow. I remember the 1702 monitor I used with my C64. Then there was the original 1080 for the Amiga. How can I possibly not remember the 1070? This is really weird.

Thanks for the information! Yep, I do have an RGB cable. I will see if I can get the transformer I already have to work. And if the monitor and A1000 works then I might get a new and smaller transformer. I think a power rating of 300W should be enought but maybe go for 500W just in case? Would this be enought for an A1000 system (I might modify it) with a monitor?

Apparantly, The 1070 model was released together with the Amiga 1000. Check out this link with a list of Commodore monitors:

Interesting, The 1070 looks like it's a. 31 dot pitch which is actually quite a bit better than many of the others which are 0.41.....

I'm in Canada and I've never seen a 1070 either, even though I've been using Commodore computers since the PET days. Maybe they were not available in North America?

Righty-ho, it's a .31.

At the Commodore closeout sale in 1994 in Toronto, Canada, there was a 1070 monitor along with a number of 1080 monitors. A I recall they were all the same price but seeing that the 1070 couldn't handle the C64 video I chose to buy a 1080.
Should have bought the 1070!
