    I just tried viletim's simplified video CXA1145 amp on X'eye, and it's a success!

    Output was a bit weird when I was tapping ground from composite video jack, so I moved it to gnd pin of CXA1145, and it got normal. According to viletim, any general purpose NPN transistors will work. I used BC548B and 33 Ohm resistors (what I had).

    I only had to add a Svid connector and couple of resistors to get S-vid out of a Xeye I have.

    So wait some X'eye's didn't come with s-video? Mine came out the box with s-video. Guess I am just lucky, to bad I run RGB anyhow from that console. Nice job BTW!!

    This works on some TVs and looses sync on some other, so with amp it's more stable. Besides the price of two caps is about the same as the price of two transistors :)

    I think almost all X'eye's didn't have S-Video. I'm lucky I got the mini-DIN connector, although RGB pins aren't connected to anything.

    I had an xeye with the right video chip on it to get s-video. I just didn't have access to the some of the components and my soldering sucked at the time.

    You sold me your X'eye for 50$ (and you bragged you got it for 30$) and also a bag of blue leds (update: actually that was from DeadperfecT, my bad!). 3 or 4 years ago :)

    So it was you! lol. never sold a bag of blue LEDs before though...

    I thought that SVIDEO port looked familiar....

    looks great. I went the other route and built a rgb to s-video external encoder for my genesis. Looks the same and this way I didn't have to mess with the system itself.
