Wow Roger, that burning CW flame with branches flying out, that is just beautiful!
I can hear from the video that it is louder than the forced air cooling, but exactly how loud is it compared to a SGTC? VTTCs tend to have a softer sound, but this seems massive!
Beautiful picture in your post of the spark, great job on this coil :)
