SSTC progress, results
Initial runs show that the full-bridge works very nicely, even beyond 3 amps DC input. After that, my variacs' current scale ends. The 10A fuse didn't blow. :o) I'm using a big secondary made of two polypropylene buckets with bottoms sticked together. #28 wire, maybe 20cm diameter, and about 40cm high, f_res around 120kHz.

Some results (pics & videos):
Streamer length is approx. 10cm / 4", at an input of 220Vac 1...3A (different interruptor settings).
Video 1 - short run with lights on
Video 2 - longer run with lights off, interruptor set to allow much power (pic on left)
Video 3 - longer run with lights off, interruptor set to pass less power (two pics on the right)
