Yoke board

Here is the yoke board with the H and V scan reversal switches on it. This board is located on the inside of the CRT flip up metal shield. Three switches reverse the H scan, one per tube, and one switch controls all three tubes for the vertical switching of the scan. DO NOT touch these switches when the set is on. Pressing one of them will instantly burn a line into one or more of the tubes, and I get about 3 emails a year of people doing this…

This board fails rarely, although some of the vertical power resistors can snap off on one side if they are bumped while working on the set.
