Swell guy, old guy. A mere Software Engineer, really, now thrust into circuit designs not encountered for about 40 years. I have just now entered the LTSpice vortex and seriously love it. Not just love it, I want a room with a hot tub for a weekend getaway with LTSpice. That aside, my short term needs are for a few LTSpice subcircuits from the good wiki types. That quest landed me at ltwiki.org.
