Chuplayer Posted August 4, 2011 Share Posted August 4, 2011 So I just nabbed this a few hours ago: eBay Auction -- Item Number: 190561605157 My only concern right now is getting a power supply to work with it. The listing says it comes with a Japanese 100VAC power supply. I've seen a pic of the back of the console that says 9V right next to the DC input, but I don't know the current the system requires. I do have a spare US Jaguar power supply. It's 9VDC at 1.2A. I have no idea if the current rating is sufficient and if the connector will match the Duo-R's DC input, though. (And I'll be mindful of center positive/negative, too. If need be, I will cut the cord and rearrange it so the polarity is correct.) Does anybody have any experience from their own Japanese Duo-R usage in the USA? I'd really like to avoid getting a 120VAC/100VAC step down transformer.

Austin Posted August 4, 2011 Share Posted August 4, 2011 I used my DUO-R without any kind of converter. No problems. Quote Link to comment Share on other sites More sharing options...
Chuplayer Posted August 4, 2011 Author Share Posted August 4, 2011 I used my DUO-R without any kind of converter. No problems. I've thought about doing that, and I may if it turns out that it outputs the listed DC voltage due to the presence of a regulator. I'm still digging for information, though.

ApolloBoy Posted August 4, 2011 Share Posted August 4, 2011 I use Japanese power supplies all the time and I've never had any problems. The Jag power supply wouldn't work anyway since the tip is too big to fit in the Duo-R. Quote Link to comment Share on other sites More sharing options...
OldSchoolRetroGamer Posted August 4, 2011 Share Posted August 4, 2011 As others say Japanese supplies are fine in US or Canada, I have a Japanese NEO GEO CD with original PSU no problem! Quote Link to comment Share on other sites More sharing options...

The Jag power supply wouldn't work anyway since the tip is too big to fit in the Duo-R. Well, I could splice the right size connector, but I'd rather not hack up the power supply as it is sent to me by the ebay seller. At least not yet. As others say Japanese supplies are fine in US or Canada, I have a Japanese NEO GEO CD with original PSU no problem! I guess nobody's too concerned about it. Well, I will have a look at the power supply when I get it. Maybe it'll say 100-120VAC, and maybe it is a regulated power supply. I can check that with my multimeter. If anybody else has any experience, please chime in! Quote Link to comment Share on other sites More sharing options...
Chuplayer Posted August 4, 2011 Author Share Posted August 4, 2011 I just got a very nice email from the seller in Japan. At the end, it says that the system can take a Genesis 2 power supply. I have one of those, so I'm all set. The range of voltages is quite large, so either the system has a big tolerance range, or there is an internal voltage regulator. The Genesis power supply is 10VDC at 850mA. That's barely over the 800mA minimum outlined below, but whatever. However, I am a little concerned. My multimeter was reading it as 13VDC. It's not regulated. But it's probably okay. The voltage will probably drop with current draw, and my Genesis 2 has been fine for nearly 15 years. Anyway, here's the email. Refer 1: How to change region mode between PC Engine and TurboGrafx-16. Refer 2: Safe suspend for CD-ROM gaming. Refer 3: How to solve for CD-ROM drive unit issue. http://homepage3.nifty.com/moremaco/slv.htm Refer 4: As you see, this console has been fine work in Japan. But, when console arrived oversea, somehow there is the case that does not turn power by unknown origin. In this case, please try it with following some AC adapters. --- SEGA (Genesis2, MegaDrive2, CDX) --- SONY (PSone, PS2 slim). --- Other products (Voltage between about DC7V and DC10V. An electric current above 800mA.) -doujindance Quote Link to comment Share on other sites More sharing options...

I purchased my DUO-R from a user over at pcenginefx.com It came with a Genesis 2 power supply and its been working great for a long time now.

Chuplayer Posted August 8, 2011 Author Share Posted August 8, 2011 Thanks for the info, everybody. I got the system today, and it came with a 100-240VAC power supply. I lucked out. There's no need to use my Genesis 2's power supply at all. The power supply is 10VDC, but it appears to be a regulated power supply. It's only a slight bit over 10VDC. I think it will be okay in the long run, but I might still go find a 9VDC power supply to replace it regardless. Quote Link to comment Share on other sites More sharing options...
Chuplayer Posted August 9, 2011 Author Share Posted August 9, 2011 I made a little introduction to my console with one of my dolls. I posted it on my blog here on AA. http://www.atariage.com/forums/blog/410/entry-8413-donna-plays-my-pc-engine-duo-r/ As you can see, it does work. I guess this thread has run its course. Thanks again, everybody! Quote Link to comment Share on other sites More sharing options...
Majestic_Lizard Posted October 16, 2011 Share Posted October 16, 2011 (edited) As you know, these older systems did not have Hard Drives, sophisticated multi-core microprocessors, or other ridiculously delicate components. As a consequence, I've found that within 30 percent of the target Amps and Voltage is usually fine. I've used Genesis power supplies to power virtually every console I've run into, with no problems (sometimes the plug has to be adapted).
