Uhhhmmm, yeah... Oops!

Open yoke. Ewww... Does this happen? I'd better check it. Solder joints were good
(through-out); check. Static resistance check on R620 was good; check. F600 continuity
tested OK; check. (I will go back and check continuity all the way to the components
though) You seem to be leaning toward a no-load condition from the yoke side, Roger, an
interesting thought. If one pulls the yoke connector off of the deflection board, does it
tend to cause only one of the drive transistor to heat? More importantly, is it going to
be safe for me to quickly test the characteristics tonight after yanking the yoke
connector?!? To see if this is the case also for the X side?

Thanks for your thoughts, dude.
