Original poster: Liviu Vasiliu <teslina-at-yahoo-dot-com> Hi list I tryed to put together a driver page for flybacks and ignition coils. The results are here: http://www.geocities-dot-com/teslina/drivers.html If someone has some good links (nice long, hot, fatty sparks and schema)just reply (only flybacks and ICs). I will put all the links on the same page teslina
