the "contrast control" as they call it has a profound effect on the picture, it can effect it to the point that nothing is seen or heard on the screen, I hardly can call it " contrast control" persey as it seems to adjust RF gain in place of modern AFC.
and yes, I was able to see the -3 at the point that said in alignment, but adjusting A4 had no affect on it or picture. a6 did have affect on picture.

this was with the signal sent into the ANT , as instructed.

I am going to send this generator back for favor of a vintage one.
i found this very disturbing
