I've been using a Sega model 2 as a power supply with the Duo R I recently picked up because it didn't come with one.

Sadly I need this for my Sega setup so I will be looking to replace the power adapter.

Any luck with somewhat "cheaper than the originals" in terms of power supplies? They are not *that* pricey, but if I could save a chunk of cash and have something in spec that doesn't cause any video interference it would be great.

I was looking at this one https://en.retrogamesupply.com/collections/pc-engine/products/power-supply-for-nec-pc-engine-duo-r-duo-rx but noticed it was a switching power supply as per this review below of one they did for the supergrapx

Could anyone recommend something that wouldn't introduce any interference? Maybe just get another Sega model 2 adapter? (seems to be 1 V higher)

(also I will being doing the voultar RGB amp soon, sounds like that could be a factor too)

Hello,

I've recently picked up a Duo R - in pretty decent shape. The A/V and controller port have been replaced since looking at them the wrong way could cause issues. lol

The caps all seem fine, but I picked up a cap kit from console5 and will probably just change them out while I have it open.

Its very clean inside, almost like no tampering has been done - the laser in it had died, but it still had the original "goop" on the laser pot. I tried adjusting the laser pot, but ended up replacing the laser now it plays original and CD-R's.

Basically it's just down to the x3 issues below (might even be normal, i'm not not that familiar with this system yet and haven't found any info on the below)

- while playing a CD game (Dracula - Rondo of blood omg how good is that game) a friend bumped the console very lightly by accident. The CD music stopped (and i think spinning) but the sound effects and the game kept going. Is this some kind of fail safe? is there a button combo to get the CD to spin back up again or a more serious problem? It just seems like any vibrations will set off the game music and you just need to restart. Maybe the magnet in the lid isn't spinning?

- so the CD rom bios menu (press run screen) has no noise when you are loading a CD. but after playing a game then using Run+Select to return to the main menu. there is a sort of buzzing/humming noise coming out  the speakers. I'm wondering if that is normal because I used the shortcut to return to the main menu or not. Again, noob here not sure if I should be doing that. Resetting the machine will remove the noise.

- there is a BA6296FP chip right under the open button, which seems to get much hotter than the other chips when playing CD games. This is apparently a "BTL Power Driver for CD Player"
again it plays cd's okay but just wanted to reach out and see if this was normal. 2-3 of the pins on this chip look black, almost burned, but they appear to still be soldered to the board without issue.

Thanks in advance, I have some TG-16 experience but still learning about the do's and don'ts of this nice Duo R :)

Hi there,

I'm from Canada, love retro systems, dabbling with RGB and arcade systems.

I've had a TG -16 now for about a year and finally took the plunge on a Duo-R. I bought it broken off ebay but was able to bring it back from the dead. I've yet to do the RGB mod and some other minor things , but I will post that in a separate thread in a bit.

Anywho thanks for approving me.
