Is this the Sega CD 2 AC power cord that works on the DUO?

I've been searching for the correct model # and a place that's selling a Sega CD 2 power cord. I'm hoping this is it.

I'm also looking for the AV cable or a replacement option.

Thanks!!

Dunno I will test mine tonight and compare specs

Here's the image:

The picture is a Sega CD 1 adapter, not 2.....the 2 tip is yellow, and specs are all wrong.
Specs on this Genesis/Sega CD 1 adapter are:  10VDC, 1.2A, tip NEGATIVE.

Duo_R has written up something on how to convert this.....basically cut the end off, strip to your liking, it requires a "Q" tip from Radio Shit (right?) AND reversing the polarity on it to tip POSITIVE to comply with the Duo's 10VDC, 1A, tip POSITIVE spec.

Hope this helps....

[Duo_R]

ok, so here are the Duo's specs:

DUO:
Input: 120V AC 60HZ 16W
Output: 10V DC 1000mA
Center plug is positive, the outer is negative.

got that from here:
http://www.consoledatabase.com/faq/necpcengine/turbografx16faq.txt


how do the specs match up on the Sega CD? So 10VDC and 1.2A - that looks good. Now is the outer tip negative or positive? If it the out connector is negative and fits we have a winner. If the outer tip is positive, then we need to reverse polarity. There are markings on the AC Adapter and on your system that indicate the polarity (so u can see if they match).


*duo runs to see if he can find his little converter box*

So this is a converter box, this is actually a Sega CD 2 to Duo-R adapter box I built. The specs were inline, but the polarity was off. I built a little box to swap polarity. Salvaged a plug from an old cordless phone I am no longer using, the box used to belong to my Duo's region switch box, cable was hacked off a Japanese Genesis cable that I didn't need.

Nice! Thanks for the info.

Here's this: https://www.pcengine-fx.com/forums/index.php?topic=2086.0

I hava a Genesis 2 power supply, but it has the yellow tip and doesn't even come close to fitting the duo. It's specs are.
10V DC 0.85A

I guess I'll go the Radio Shack route. Pick up Q tip and try to reverse the polarity if need be. Not sure if the Genesis 2 power supply will work. If not, I'll order the Sega CD.

So this looks like another solution. Kind of expensive though.

So, will the Adaptaplug Q and the 9.0VDC International-series high-power AC adapter from Radio Shack work?

Just looking for cheapest and easiest route. Don't mind doing a little modding.. I'm not much of an electrician, but I can follow a tutorial.

OK, I've been seeing conflicting information on this Genesis 1 adapter, so I pulled out my box of them and inspected....here's what I came up with:
1)  Sega Genesis/CD 1 adapter, Model 1602:  9V DC, 1.2A, tip negative, type M.  [this has been the source of my confusion]
2)  Sega Genesis/CD 1 adapter, Model 1602-1:  10V DC, 1.2A, tip negative, type M.
3)  Sega Genesis/CD 1 adapter, Model 1602-3:  10V DC, 1.2A, tip negative, type M.
[didn't find a "-2"]

In terms of electrical stability, the later the Model, the better off you're gonna be.  Hit up the local flea for the $1 "1602-3", cut the end off (noting which wires were negative and positive), solder on the "Q" tip in the required tip positive manner and you should be good.

DR is talking about literally that:  a Duo-R.  Is the AC adapter spec for this the same?  This would explain why he's talking about a Genesis 2 (Sega Genesis/CD 2 adapter, Model MK-2103:  10V DC, .85A, tip positive, type C), but Chopsado talks about running a regular Duo with a Genesis 2 adapter (and the unique tip size adapters!) in this thread:

I'm totally confused about this, the mA for it is too low, I'd think you're underpowering the thing, but he said it ran better.....the mA rating is the MAX amperage the thing can provide.  If the manufacturer shipped it with one that says "1000mA", wouldn't you think something inside it is capable of drawing that?  If this is true, then 850mA is underpowering it....the fact that the thing apparently works better is puzzling.

Anyway, check the mA on the generic Radio Shack....if memory serves, it's like 1300, which would work, provided the max amperage on the unit originally provided by the manfacturer was 1000mA....in theory, the unit is incapable of utilizing the extra 300mA in this case....

Comments, anyone?

["Dammit, Jim, I'm a doctor, not an electrician!" seems strangely appropriate here]

[gat]

Sweet! I'm starting to get it now. Great Trek quote btw!

I have a Model 1602-1 from my old Sega CD. So I'll use that with the Q tip I just picked up from Radio Shack.

So, it's almost solved. Just need to do the soldering work... and I need to get the AV cable worked out. Then I can test my system.. which I think might be broken. 1 step at a time.

[Duo_R]

Ok,


the original post he is saying he needs an AC adapter for a Duo. So again here is the specs:

DUO:
Input: 120V AC 60HZ 16W
Output: 10V DC 1000mA
Center plug is positive, the outer is negative.


The output specs is what we need to pay attention to: 10V. You want voltage to match almost exact, more or less isn't ideal. Now mA is different, the important thing is that you need to have something AT LEAST 1000ma, you can actually have more mA (or A) since the Duo will only pull the juice it needs. Going less on mA is not good for the system since it isn't providing enough amperage (regardless how someone says it is running). OK? 

I'm totally confused about this, the mA for it is too low, I'd think you're underpowering the thing, but he said it ran better.....the mA rating is the MAX amperage the thing can provide.  If the manufacturer shipped it with one that says "1000mA", wouldn't you think something inside it is capable of drawing that?  If this is true, then 850mA is underpowering it....the fact that the thing apparently works better is puzzling.

Mmm...froggot to mention that Sega Genesis/CD 1 AV cables will work fine for the Duo....I traced the pinouts the other day on both the two-tail (yellow/white) and three-tail (yellow/white/red) ones, they both comply with the Duo spec.

[gat]

Nice! THanks for the info! I'll be rocking in no time.

[gat]

Sweet. I don't have the AV cable, but just picked one up off ebay.

[agt_dale_cooper]

Uh, if that's the AV cable in question, it ain't right.
That appears to be a Genesis 2 AV cable...what you need is a Genesis 1 AV cable, 5pin DIN interface....[refer to previous post text..]

Here's a nice little make your own Genesis 1 AV cable (Radio Shack is going to get tired of seeing you) :
http://www.stageselect.com/News/NewsViewer.aspx?newsid=174

Just make it comply with the Duo spec:
http://www.gamesx.com/avpinouts/duoav.htm

(Note that pins 1 and 5 are the same, just wire in pin 2 to red and off you go....)

[gat]

I have a 5 pin cord that fits the duo.

Like this



but in chord form. I stripped it and it has yellow, white, red and black along with the copper. Would I be able to wire this to a standard AV cable?

[agt_dale_cooper]

Ah, you have the correct piece.
Yes, this will work, as you've cut the non-compatible end off the Sega 2 AV cable...replace with the 5pin.
Use the Duo wiring spec provided above and you're golden!  Enjoy when done...

[gat]

OK. One last noob question about the power supply I think I'll have everything solved. 

I have a stripped Model 1602-3 genesis power supply. An adaptaplug socket and the adaptaplug q.

Once stripped, the Genesis AC has yellow and white cord. The adaptaplug socket has the 2 white cords and one cord has writing on it. I presume that I wire the positive to the positive and negative to negative on the Gen AC and the adaptaplug socket then just flip the adaptaplug q to reverse the polarity.

Question: How do I tell positive cord from negative on the Genesis AC and the adaptaplug socket? I'm guessing since the tip of the genesis power supply is yellow, and it's a negative tip.. the yellow would be negative. And which side is positive / negative on the adaptaplug socket?

Just being extra cautious.. thanks!!

[gat]

YES! I found the answer to half my question on the google.

"For the AdaptaPlug socket, look for the word "Tip". Face that mark towards you. The wire on the LEFT is POSITIVE, the wire on the RIGHT is NEGATIVE. ..."

[gat]

OK. So.. got everything wired and the power is on. I plug in the Duo and hit run and the busy light comes on.. disc isn't spinning though.. I'm sure it's throwing a SET DISC ERROR.. but I won't know for sure until I get the AV cable.

I just guessed on the + / - for the power supply. One would think there would be a plain and clear way for us non electricians to tell.. the + and the - don't even match up to the two prongs on the ataptaplug q. I just tried both ways and one way turned the duo on.. so.. i'll leave it as is.

My next thread will prolly be "My Duo doesn't work"

[agt_dale_cooper]

Busy light comes on...this is a good sign.
On my Duo that the CD-ROM drive doesn't work, busy light does NOT come on.

Try tuning the laser....it's the grey phillips screw at the side of the laser assembly itself...a SMALL amount clockwise (a little goes a long way on this screw..)  MARK where you had it before you turn so you can get back to ground zero...

Finish your AV cable so you can figure out what the frell it's saying first, though...heh.

[Duo_R]

for the non electricians, go grab an ohmmeter! Don't take a gamble on the + and - when you can easily figure it out with a $5 tool (for the cheap ones).

Nice, I will def get one.. with all the modding I do, might be good to figure out the basics.

I'm assuming these 2 cords won't go together since one is the Sega 9 pin??? My radio shack didn't have the 5 pin din plug, so I picked up the 5 pin cord and spliced it up. Which is here:



And the Sega 9 pin spliced up:



So so so close..

[Duo_R]

They are pretty much the same thing.

Yellow - vid
Red - right audio
White - left audio
Black - ground
copper strands - ground

One just doesnt have a ground line, but that is ok. Ground is ground, twist them all together and connect to ground / shield.

The black cord turned out to be the video. Not sure what yellow is. I have no sound through the av cord. I've tried every possible cord combination for the sound and nothing. When I plug headphones into the earphone jack, I can faintly hear some sound out of one ear. Like hearing test quality. Very low 

Turbo Chips work and play fine. CD-ROM hangs at JUST AMOMENT...

So. Is it worth sending to get fixed or cheaper buying a new one off ebay? I'm the og owner, so this system has some sentimental value..... But, I'm dying to play some Ys, Bonk, Lords.. and so oonnnnnnnnn!!!  AHHHHHHHHHHHHHHHHHHHH

[Duo_R]

well if you are plugging into the headphone jack on the Duo and getting faint sound, sounds like a cap issue my friend. And you are having laser issues too. This Duo needs a full makeover....

The laser might just need calibration, but it is likely to be dying/dead. Cap replacements are both cheap in parts and in labor, there really isn't much involved in doing a cap replacement provided you can solder, I am not sure how much the duo laser replacements go for, I am thinking the can cost anywhere from $35-$45. I could take a look at it for you, and I can tell you it will definitely not be more than $100 to repair, not even close, unless duo laser replacements have skyrocketed in value.

[Duo_R]

Lasers are still $18, but honestly, a full Duo makeover would be replace laser / and the audio caps and maybe even a dishwash....  and even all that should be < $100.

Thanks!! Under 100 is greeeat. I can't believe people put em in the dishwasher.. I was reading in another thread and thought it was a joke. I'm assuming it cleans out all the funk?

It does, Nat is the one that told me about it. It works!

Thanks for the help. I'm sending my duo to a fellow board member for repairs. I'll be up n gaming real soon.
