Guest liquibyte Posted October 13, 2014 Report Share Posted October 13, 2014 That was the consensus by Tim too. I'm wondering if the 2N3055's are at fault here in some way by allowing voltage and current through at power on by being hit by the initial surge. Is that possible? Would a higher Vceo help with that? I'm certainly no expert either but since I started using LTSpice, I've been learning a bit faster than I was. It's a neat program once you get used to how it works. Quote Link to comment Share on other sites More sharing options...
