Nintendo Donkey Kong Jr Monitor Magnifying Picture ??

I have a neighbor with a DK Jr. and the monitor needs a cap kit....but it also has a problem that I have not seen before...the picture is magnified....meaning all the game pic is larger than it should be. Thoughts?

The B+ voltage is probably too high. The adjustment pot is flat on the chassis near the regulator IC. The test point is labelled BJ. Put the red lead from your meter on BJ, black lead to the frame. Adjust the control until you get the proper B+ voltage of 108v.
