I had to replace more parts to get to this point though, turns out the 'I' section of the chroma channel was completely dead. That ended up being, surprise surprise, another bad peaking coil. This time it was the one feeding the 'I' phase splitter, which led to complete lack of 'I' information to the matrix. The clue was the 'I Gain' pot having no effect on the picture, and the colors being generally messed up. Replaced it with one of the ferrite spares I had floating around, and it perked right up.

Still remaining is the IF alignment, which I totally screwed up earlier. I think I'm going to have to use the mod marker function of the 415 to tune all the coils independently first, then move on to a regular alignment to finalize the response. That will allow me to finally get some DVR stuff on the screen, to see how well it really performs. I'm also noticing a slight drive line in the picture, even though the pot is at minimum. I'll probably have to change some values under the hood to get it a tic lower, so the line will go away. Other than that, it's looking pretty good if I do say so myself.
