I haven't had a CG or CG2 since before the jb fix was published, and none of the reference photos that I have show enough detail to trace them out visually.  The PCB layouts are very very similar and I wouldn't be surprised if the applicable caps are in the same location physically.  Without a clear photo I can't publish any for sure values.  NEC did seem to retain their designators across similar layouts so I would not be surprised if they were the same numbers!

Have you performed this cap replacement on your SuperGrafx?

How are the results?

I have done the jailbar fix on my DUO and DUO-R and the results were AMAZING, absolutely no trace of any kind of jailbar.

On the other hand when I did the same on the Core II the results were far from perfect (C131, C132). Yes I could see a difference but it was more like the jailbars bacame much thiner and less noticable instead of absolutely going away. You can still easily spot them though.

Anyone else have jailbar fix experience on the Core II?
No, sadly I've been lazy about my own consoles. Something about the mechanics car always being broken 😃

I took the photo in the above wiki link from a spare SGX sitting here.  I'll add a PAC N1/10 pic soon, too.

Oops, I shifted the numbers up in that reply.  R200 and R201 are 562

I would attach an image but "The upload folder is full"

I've got one here and each resistor in both R201 and R202 are marked 562

On the bottom, C168 and C169

For a few hours on Friday night.  Turbokon introduced us, we chatted for a minute, and then I believe you were carried off by a pack of rabid dogs and/or colorful butterflies.  That might not be exactly what happened.  Powerful stuff, that Spotted Cow.

That was another fun year!  Was nice to talk to a few new and a few old members again.  A mighty brain fog rolled in from New Glarus, so if I said anything crazy I swear it's not my fault.

Now, back to lurking until 2016.

To help the OP, I need to reference a Duo-RX with PCB code PWA-3365-A. 

It'll take too long for me to import one, so if someone here has access to a RX and can send some pics and confirm a few part values, I'll gladly pay you for your time.

OR if you have a Duo-RX for sale (dead or alive) in the US, I might be game for that as well.

Hey guys, based on the feedback posted here, I wish you would have sent me an email explaining the problems that you'd observed.  I work to make things right in any sale whenever humanly possible.  That offer is still open to any of you, just send me an email!

To the OP - I've sent you a reply (if that was you that emailed me) for a little clarification on the differences between your DUO-R and the more common 3339-A revision.  We'll get you figured out!

I realize that premade kits aren't for everyone and that's OK.  The big difference is if you buy caps from Mouser and things don't go as planned - you get the wrong size or things act oddly - Mouser won't be really help you at all unless they parts were patently defective.  If you order them from me, I help you get it working correctly or refund your money!

Some kits will come with extra parts depending on the hardware revision.  Usually this is done to simply the assembly & ordering process.  Especially Sega hardware where they just couldn't quit messing around with it.  At least with NEC it was pretty much one design and done which is what makes the OPs DUO-R revision intriguing.

Stopped by last night after going to a few bars downtown.  Apologies for my verboseness...I was in rare form  :mrgreen:  Great setup!
