RE: G08 deflection problem

 Well, since nobody else responded yet I'll chime
in. First, what effect does the HORIZ WIDTH, H CENTERING,
VERT HEIGHT & VERT CENTERING pots on the board edge have
on the image? Have you measured the power +63/-63V supplies
to see if you have the rated negative voltages? The pictures
look like the scale and linearity are OK, are they really?
