Sounds like a successful Crowbar test. I like those. Silent, all that current 
dumps, and the transmitter survives. When the crowbar DOESN'T trigger fast 
enough, then all H--- breaks loose. Thats when you vaporize wires and melt 

#29 and 30 AWG magnet wire are still a standardized test method for high power 
crowbar protection for tubes.

I didn't know you were in Roswell (KBIM), the UFO capital.
