Powerful high voltage flyback driver (no low voltage transformer, powered by rectified mains!), altough the switching spikes were too much for the poor horizontal output transistor (HOT). Sparks were at first 2cm, then something went wrong in it and suddenly it gave 8cm hot arcs!

And then, the 10R 10W protection resistor fried, along with 50% the components (acting as a fail-safe fuse :-) )
