 | Hi all, 
 i just connected my 48 volt 2350 watt psu on the ignition coils but the transistor died after 1 second of HUGE sparks ( >10 cm) with almost constant output .
 also i adjusted the frequentie to 300 hz according to the hz counter on my volt meter.
 no idea what the on / off time is do.
 i fiddle with the pots to obtain the largest sparks , which are 8 cm with 12 volt with a little more then 1 spark each second.
   
 damn shame the transistor cant take the 48 volt, was curious how long the sparks would be   i could draw
   gonna try some other resistors on the snubber and see where i go from there.
 greetz,
 
 Marco
