and ... yes .... the audio here is solely generated by the sparks no other speaker around

supply 330VDC (rectified 220V AC), half bridge power drive, 17 turns primary, ~1200 turns, 30AWG secondary. Audio played by driving audio signal to the VCOin input of the PLL... as suggested here: rayer.g6.cz/teslatr/sstce.htm (roll to the bottom of page) i did not draw the schematics ... just built it from my head... so feel free to ask specific questions BTW - when not audio modulated, the sparks are~10" (about the height of the secondary) when i turn on audio modulation, i offset the PLL phase to higher frequency (half size sparks) to have some "sparks growth potential" for the modulation
