The problems with the mod become apparent as it goes under increasing levels of scrutiny. Although it might look fine on a CRT, the "lens" that you are looking through is very blurry. On the other extreme, the clearest lens is through an oscilloscope of sufficient bandwidth, where it reveals a hopelessly distorted signalcaptaineos wrote:Me again. I read the chat about blur and overshoot and later technical improvements related to the amp.
I, for one, must be lucky as I have what I consider to be a pristine image with Buttersofts PCB that I've written about earlier.
I am posting becuase I thought maybe I was over-estimating the sharpness as clearly there is some blur that people have. I went back and took this photo - edges look clean to me. The cable is custom and my PAL console has C-SYNC restored.

Personally, I'm aiming for the best appearance I can get after optimal 8-bit digitization, since the hardware is currently available to us hobbyists. In this realm, the problems with the JP mod are clear and solutions are difficult to find. However, even if it might be a fool's errand, I believe I can reach a point where it looks "good enough" for me. You found your settling point with your equipment setup and that's great too!
