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
