Tea4Two Famicom - is it worth it?

[zmaster18]

Lately I've been looking at the Tea4Two Famicom AV mod and am considering getting one for myself, but I'm confused. There's little information about it in english and I'm having a hard time getting the answers I need.

First of all, is the video jailbar-free? I believe this is the ultimate AV mod for a Famicom, right?

But then I look at the different kits they sell, and there seems to be 3 kits just for the AV mod. There's the regular AV mod kit:



Then there's the AV amplifier kit. This one seems to be more advanced than the previous:



And then there's the PPU stabilizer. I believe this is used with one of the kits mentioned above and it isolates the noise from the board so it doesn't get in contact with the PPU:



Which one should I get? Will these kits guarantee jailbar-free video? I've never actually seen a screenshot of the Tea4Two Famicom in action. Does anyone here who has one recommend it?

That honor goes to the NESRGB: http://etim.net.au/nesrgb/index.htm

I'm talking about composite AV though

The NESRGB outputs the cleanest composite video you will ever see come out of any Famicom

I thought NESRGB tricks the Famicom to spit out an RGB signal?


I've seen Tea4Two (probably an older mod since the icon logo on the sticker isn't one of the existing icons on their homepage) and it looked like there was still faint jailbars from what I can tell. They weren't really noticeable when you play though.

gyus, there're no doubts with faint jailbars and with what it causes. Shielding of PPU completely eliminates those remaining faint jailbars.

there's a long av mod thread where 80sFREAK was arguing about jailbars and their root cause with almost every one. Then it turned out, the we have managed to figure out the root cause.

as an outcome, 80sFREAK have created the following thread http://www.famicomworld.com/forum/index.php?topic=8080.0

well, i coudn't agree more.

So, without PPU shielding, you will always get faint jailbars which might be more or less noticeable depending on your TV (any TV does signal processing and noise filtering in a very much different manner than probably others do). It's an obvious flaw in engineered design of PPU IC. Just deal with it.

I would say these are worth it if you just HAVE to have a TEA4TWO Famicom.  They do have jailbars but are nice boutique items I think.  They're not necessarily good value, so it depends on what you want.

Stealthlurker actually has one of these from a few years back - recommend shooting him a PM for his thoughts.

I would like to get one some day, but it's not something I imagine would get much if any use, a (new model) AV Famicom with NES controllers has better value I think.

I noticed that the AV amplifier has a noise cancellation IC on it. Does this help with jailbars? Or could extra components make the picture more blurry?
