Well that should be easy. With just a SCR and a trigger transformer per 
stage, take your pick!. :-)

At present, the OLBRISG coil is running V.2 SISG trigger board, and 
producing 48 inches/120cm ground strikes with one single CM600 running 
4kA peak. At these currents it gets tricky to measure stuff. There are a 
couple of volts/centimeter, even in wide conductors.
I`m out of range on the scope with a Pearson 101 and 500A/division. Well 
I guess I could halve the sensitivity by terminating to 50ohms. I think 
the bricks are good for more current, they don`t get hot at all.
