Well, I got all the pins lifted off the VDP without issue (nerve racking lol)

I followed the steps here – as I also have a NTSC VA3

It syncs up with the OSSC and plays fine, but It just looks odd. Pretty much exactly what my other VA3 (with just pin 50 cut/composite) so it still has some vertical lines and blue seems a bit funky.

I am nabbing the 5V from the 7805 regulator, but I ran the ground to a common location. I’ll try moving that over to the regulator as well.


@nzChris – sounds like you spoke with voultar in another post – do you think cutting pin 50 might do the trick?

Also I am running Revision 2 of the RGB amp.
