When I pull the 6AL5 detector, the line goes away. I am sure I have not miswired any caps.
With no video there is no line. If I lower the contrast, the line gets dimmer. If I adjust and increase the contrast it gets brighter at the mid point of the pot as shown in photos, then decreases and shrinks back as I increase contrast as it seems to overdrive the circuit as shown in the photo with thinnest line. This test was done with my signal generator with a cross as shown.
