Hey all, I found a package containing models for LTSpice (including the TIP41 that I need), but have no idea how to install it. The archive is here: http://www.onsemiconductor.com/files/ZIPModels/OnSemiconductorDiscreteModel= s.zipand it's around 6.3MB. Can anyone offer some advice? --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
