Still working with this one. It SEEMS to fundamentally be working now...with the exception that I am only getting a B&W image. I'm gonna guess something is not passing through on the chroma circuit. Are there any common fail points for this part? I only tested the delay line a bit and that seemed to be working fine. But I'll let Kolchak tell the rest of the story:
Adjusting Hue and Color Level also change nothing, by the way. All other controls seem to be working okay.
