Hi there, I built this project (picutres to come) on a vero PC board with a 15 pico farad capacitor, and the NTSC colourburst crystal (3.795 etc Mhz)
I am not getting any colour from either the Composite out, or the Svideo jack. I'm guessing, from what I have read on the "
Amiga RGB to S-Video + composite adaptor" thread that the capacitor might be the issue.
If the issue was just the svideo jack then the problem might be the chroma out put, ( bad connection etc ) but seeing as it's on both the composite (generated in chip) and the svideo, I'm guessing it's a timing issue with the crystal and capacitor. I will try a 20 pf.
If I need a variable one. what would be the best value to purchase?...
