Continuing the saga of the healthkit gr-25

[Phil]

After replacing the diodes and resistors on the convergence board I was able to achieve very good convergence, mostly off in the upper lefthand corner. The single remaining issue is the picture is off center to the right. There doesn't seem to be any centering control on this chassis. The yoke seems to be straight and can't be canted on way or the other very much. So, the question is: why would it be off to one side? All my older sets have centering controls so this new fangled design is different than what I'm used to seeing.
