My 25K7000 test rig is a tube I salvaged from a TV (and yoke) along with the original yoke connector from the original tube.
Stupidly, I don't have the yoke connector hooked up to the yoke wires very securely. And, hooking up color to color (red to red, blue to blue, etc) makes the picture reversed. It's never been that big of a deal, I always make sure nothing is touching before firing up a chassis.
When I went to hook up the tube to a chassis, I found that two of the wires had come disconnected from the connector. Without thinking about it, I just swapped the wires, thinking that it would be nice to see a proper picture.
Yeah...dumb. The equivalent of swapping horizontal and vertical. Now, the chassis has a B+ of ~12VDC. A brief moment of high voltage when it's first fired up, then that's it.
I'm assuming that the voltage regulator is toast, to start. What else?
