The third uses the tuner slug to get the 47.25 marker at %50 of the slope. The max it would go was in the %40-47 range. Bandwidth centering and flatness of the main curve were to spec... granted even with the tuner osc disabled the curve would change from channel to channel...most were an amplitude shift but a couple changed the shape...some showed the dip above the 47.25 trap and some didn't...
I finished the video IF alignment 2 nights ago. I think I did okay the picture and sound have not gotten worse (not much better either) and yesterday morning my by eye adjustment of the chroma osc would hold lock for about an hour if I let faces be a bit greenish and 10-30 min if I had the osc on the edge of it's lock where faces looked normal... All and all I feel like I did well for my first attempt at doing a Video IF alignment on a TV.
