  1. I need to simulate a circuit with an lm393 comparator in it. I went to the
    yahoo group and got a file called lm393_st.txt. I renamed it lm393.sub and
    put it in the sub folder. Then I drew my circuit using a universal op amp
    symbol, which I named .lm393. LTSpice doesn't recognize it, with or without
    an include statement. What do I do?
