Dear List,

I managed to get an IGBT brick-powered OLTC to work. So far it has only 
produced tiny 4.5" sparks at 10bps but I believe it has shown there is no 
major problem with using bricks.

It used an 8" single turn primary, four 1uF geek group caps, and the 
secondary/toroid borrowed off my mini OLTC. Current in the brick was about 
1600 Amps at 130kHz. I never even bothered tuning it ;)

I would like to say a big thanks to Terry Fritz for contributing ideas to 
this project, not to mention bricks and caps :)

Steve C.
