Yeah, 'specially since the little blocking transformer (T2) has been changed, the osc. might be running too slow for the vert. hold to pull it in. If so, the 1.5 meg resistor (R65) coming off the top of the hold control would be the first thing to tweak.

Hell, don't think of them as blunders. Think of 'em as learning points.
