Thanks for the information Terry. I put the VA62 back to "external modulation" and took a look at the video at the first video amp. It did not have any video sync at all, so no sync overshoot, that's why it does not have the white line. I will take another crack at the alignment but this time I will also look at the video waveform as I move the sweep and marker generators through the stages to try to understand which has the most impact on my overshoot problem.
