Convert A4000 PSU from 220V to 110V

[captainmoomoo]

Hi,

I have an A4000 from the UK, but now I live in North America. The question is, is it possible to convert my PSU from 220V to 110V, or do I need to buy a replacement PSU?

I already have a 110V to 220V step-up transformer which does the job, but this is a bit inconvenient as it's shared between 3 other devices.

If a conversion is not possible, would a replacement even work, as the machine is PAL?

Thanks,
Piyush

Thanks Kronos,

But from what I understand, the mechanical switch then no longer works - is that correct? I'm really looking for a solutions which maintains the "integrity" of the A4000.

Hi Mechy,

I'm ashamed to say that despite having an electrical engineering degree, I'm not handy! I'd be happy to buy another A4000 110V PSU - but I can't seem to find one anywhere!

And since moving to Montreal, I have discovered one more problem... TV's here don't have scart inputs!

So now I'm at a loss at how to connect to a TV... can anybody suggest a solution for this?

You hit the nail on the head freqmax!

I found the following PSU on eBay, but it feels like quite a risk due to the cost: http://www.ebay.ca/itm/Commodore-Amiga-4000-Desktop-POWER-SUPPLY-Tested-and-Working-RARE-/320767296493?pt=LH_DefaultDomain_0&hash=item4aaf3883ed#ht_500wt_1286

What do you guys think?

So wrt the video output - I've managed to find a few places that sell SCART-to-YUV converters so I may try one of those.

BTW - here's the scart-to-YUV converter I found: http://www.ebay.com/itm/NEW-SCART-RGB-YUV-Component-Video-Converter-Scaler-/220698772855?pt=LH_DefaultDomain_0&hash=item3362ac0577&afsrc=1#ht_1440wt_1269

Anybody have any experience with this?

Hi BuzzFuzz,

OK, I've managed to change the video output to NTSC by setting the jumper. How about the PSU conversion? Do you have any further details on this?

Hi Piyush,

If you decide to try an atx psu mod and arent't comfortable doing it yourself, I'm in the Montreal area and could offer some help if you like, just let me know.

Hi Merc,

Thank you very much for the kind offer - I think I'll take you up on it!

I'll follow this up with a private message so we can arrange a meet.
