  :shock: i had a power tube let go today and thank god it did not damage anything except for my nerves  8-[  there was a bright blue Arc inside the tube from top to bottom. i switched back to my favorite and almost unobtainable 2nd generation Ei KT 90's until the Winged C 6550's get here from Chicago.thanks....WCW III

Ok, so where are the photos?  Sounds cool. ;)
Can you at least make a "artist's rendering" of the event? ha...

Seriously, glad your gear is in good shape...  and glad it happened when you were nearby, paying attention, etc.

Yeah Weez, a few days before the Lightning storm effect took place ,i had just turned on the rig and the phone began to ring and as i picked up the phone i heard a loud pop! which was the fuse. the sound did not come from the speakers themselves but from my Audio rack. i ran over to the rack to see that the other tubes had stopped glowing except for the KT88 in the LV4 position which then took a little longer for its glow to disappear. i replaced the fuse and rebiased the amp and everything seemed fine for the next few days. i switched on the amp a few days later and the fuse blew again. this time when i replaced the fuse and turned on the amp the KT88 in the LV4 position looked like something that Tesla himself would have been experimenting with :duh it was really scary stuff and i turned off the amp as soon as i saw it and i was very lucky that no harm was done to it. thanks....WCW III
