Here's a scope trace, maybe you can get something from it.

Bottom is the composite output from the generator, top is from the grid of the second video amp tube. It does look like there's some fuzz on the blanking pulse, like the whole signal slid over a little. If so, are we talking sync issues or IF issues?
