The mods I was referring to were the 50 ohm resistors. What I didn't
realize was that all green boards (except mine with the Penn Trans -
which had been raided for these parts in the past) already have these
mods in place. After reading MK's article, I restored the board to it's
original condition with these mods in place. I just finished testing it
and it works! Unfortunately after a couple of minutes the picture
begins to fade out of focus. Any ideas?

Thanks All,
