Convert a Mac Plus power board?

Hi.

I have just moved from the UK to Japan and of course I took the best examples of my classic Mac collection with me. Most items have switching power supplies but sadly this is not the case with my Mac Plus.

Does anyone know if I can convert it or do I need to go down the costly road of buying a 100v power board or converter?

Love to hear any ideas.

If you look at the board, it has a couple of areas that have an allowance for 110V or 240V, as the board is the same - note that it says 'International' on it. I would think, based on this, that you could de-solder and re-solder to make the board compliant. Not sure if it is this simple, maybe others could advise?

Wow, did not realize that step down transformers were that cheap. That might be the easier solution. Also still open for changing the board or swapping it as that would be the cleaner solution.

Wouldn't you need a step-up converter? Japan has 110V and your Mac expects 220/240V, yes?

Just thought I would follow up. The power converter arrived in the mail and works like a charm. Get's very warm but what do you expect from a 14 buck transformer?

Excellent....

The Mac Plus International PSU is convertible 240/120. No need for an external voltage converter. I have never done it, but I believe it is a simple matter of changing a jumper or two.
