Hi
What would be required to convert an American 120v A3000 to work in the UK on 240v?
Also if the above conversion is possible what are the steps to get OS3.5 loaded on the machine?
The machine has a Mercury 040 card with a Picasso 2 graphics card.
This is my first big box Amiga, A500 then A1200 before this, but many years ago. Been visiting a.org for years now, but this is my first post, so hello everyone :)
Kind Regards,
Paul

with out looking at one right now im not sure, but often there is a switch on th back of the power supply that alows you to select 115 or 220 volt. Not sure tha amiga 3000 had that. Otherwise you have two options
1 get a new 220 3000 power supply
2, get a stepdown converter, a big box that converts the 220 volt 60hrz to 120 50hrz.
It's realy importatnt the the converter you use also steps down the hrz otherwise you will blow the thing up. Do NOT use one of those univeral traveling converters made for shavers.

The standard voltage converters are just transformers and do not change the frequency. Converters that include the frequency must be high quality (non triangular wave, trapezoid is better, sine is perfect).
However, using a simple transformer without changing the frequency is no problem, just change the tick jumper to vertical blanking (otherwise the clock will run slow). Usually switching PSUs have no problem with 60/50 Hz change.
Actually the best solution is to swap the PSU for a 240V one.

Thanks for the comments.
Any ideas where I could get a 240v power supply from?

wow realy? I thought the frequency was important, remember my dad blowing up his IBM XT in france when I was a kid..... well good to know.
