Maybe for vertical sweep, but I *did* have horizontal sweep before hooking up the one errant wire in the tuner, and before I realized that another wire was grounding out to chassis. The next step here is to pull the tuner drum and see what's going on with the wiring in there. I noticed that one of the wires inside the tuner was coming out the wrong hole, meaning that someone was in there fooling around at some point.
Did your set lose sweep entirely with the GTB tubes?
