1st is the closeup of the vert sync pulse off the plate of the sync sep tube, this is using a composite video from the converter box injected at the grid of the video amp. this produces a very nice pic, no line pairing or as I have recently read "scan lines".

2nd is using the tuner and a RF signal from the same converter box, this results in "scan lines" that can not be dialed out with the vert hold.

3rd is the grid of the 1st video amp, I prob should have looked at the plate from that to see if the video amp acting up as well, that is the bottom trace, the top is the composite video from the converter box.
