HV is really about 1.5KV.
1st pic the scope is connected to the control grid of the HO tube, so everything up to that point looks ok, vert. out of the scope is hooked to the counter, and the horizontal frequency looks ok too.
2nd pic shows what's on the screen, it should be a straight vertical line, the yoke's just turned.
Strangely, if I turn the horizontal frequency down to around 12.5 - 12.7KC, the picture gets a little wider, and the HV goes up to around 3KV.
HV drops immediately when I pull the damper tube. Horizontal yoke winding is not open.
