Yes, but you will notice the voltage input is rated only for 100v. House holds here in the US are 115v - 117v with many like the 'Tower' actually providing around 125v from my outlets. So it is advisable to use a step down transformer when using JPN PSUs on US outlets. That said... I would need to verify the jack but I'm pretty sure I've just always used a 5200 PSU to power these models. As they are an AC PSU, the console has the needed rectification inside it to convert the power back to DC that it then feeds into the same standard 7805 regulator that has been used forever. So a DC supply can also be used without issue just like an original NES. Quote Link to comment Share on other sites More sharing options...
ApolloBoy Posted April 15, 2023 Share Posted April 15, 2023 When mine gets here I could check to see what kind of voltage that brick's putting out. Some Japanese PSUs are fine and dandy with 120V, but there are a few (i.e. Famicom HVC-002) which do put out considerably higher voltage and heat with 120V. In those cases it's honestly much better to use a different PSU than go through the trouble of using a stepdown converter. Quote Link to comment Share on other sites More sharing options...
+Mitch Posted April 15, 2023 Share Posted April 15, 2023 Or use the power supply from a Sears VA2. Mitch Quote Link to comment Share on other sites More sharing options...
ApolloBoy Posted April 16, 2023 Share Posted April 16, 2023 On my SVA II I just use the same 9V DC Triad that I use with a load of other systems, and the 2800 won't be an exception. I just want to examine the 2800 PSU and get some information out there. Quote Link to comment Share on other sites More sharing options...
ApolloBoy Posted April 16, 2023 Share Posted April 16, 2023 While we're on the subject of power supplies, I've noticed that the 2800s that I keep seeing for sale in Mexico have the same one bundled with the SVA II, like this one here: https://articulo.mercadolibre.com.mx/MLM-2034862996-atari-2800-_JM I'm curious if anyone else has one of these Mexican 2800s...

I actually do have a step down converter as well as, a couple of SVA PSUs, but I’d rather use the appropriate PSU with the converter.

I've never seen one, but I have two of these PSUs. One came with my SVA II, the other I purchased as a backup. Quote Link to comment Share on other sites More sharing options...

Interesting, I didn't know they sold the 2800 in Mexico. I thought it was Japan only. The power supply make sense though, since it is a North American power supply.

There seems to be quite a few of them for sale on Mercado Libre at any given moment. From some of the other evidence I've seen thus far, they seem to be internally identical to the SVA II (meaning their RF modulators are tuned for US channels 2 and 3) and not just Japanese 2800s dumped in another market. Another interesting thing I noticed is that the PSU in the lot I linked to has a 1984 date code (1884), so the 2800 might have been released there in the months leading up to the Tramiel switchover.

+bent_pin Posted April 23, 2023 Share Posted April 23, 2023 I like the later model TIAs that handle more elements. Was there anything particularly special about the TIA in either 2800? Quote Link to comment Share on other sites More sharing options...
ApolloBoy Posted April 27, 2023 Share Posted April 27, 2023 My 2800 arrived today, everything was accounted for and in very good shape. As promised, I checked out the PSU and it was putting out close to 12V AC without a load. However, when I plugged it into the 2800 and measured the voltage input to the 7805, I was getting about 13.5V DC and the heat sink got pretty toasty as a result. Definitely wouldn't recommend using the original Japanese AC adapter unless you need to perform a quick test or something. Also, I was curious about the RF modulator since it seems to be the only internal difference between the Japanese 2800 and the SVA II. It's part number CA019628 which I found zero information on, so this is definitely a 2800-specific part and not a typical 2600 RF modulator that was simply retuned.

ApolloBoy Posted May 1, 2023 Share Posted May 1, 2023 Here's the inside of the 2800 modulator, looks like a pretty typical 2600 RF modulator... Quote Link to comment Share on other sites More sharing options...
