I never identified the problem, but apparently something was shorting with the LPF board snug against the main board. With the LPF board pried slightly away there is no problem. I do not think it is a cold solder joint since I can now tap the boards, wires, torroids, etc and nothing bad happens. Perhaps when installing the LPF board against the main board a piece of tape or other insulation between the boards would prevent a short..."
----------------------------------- There should be nothing to short to on the KX1 main board under the LPF1 board. There's only one solder pad under the LPF1 board. That is for the inductor common lead from the LPF. (Originally it was one of the inductor lead pads.) I wonder if you were shorting the inductor common lead to something on the LPF1 board? It's a bare wire that has to bend over a bit to reach the solder pad. Could it be pushed up against one of the solder pads on the LPF1 and causing a short until you pull the LPF1 away from the KX1 slightly, which will straighten and move the inductor common lead slightly?
