I'm using the only model of the LM386 I was able to find on the Web in
LTSpice, but discovered that it has a major flaw: the output doesn't sit
anywhere near halfway between Vcc and ground.  I'd be thrilled anyone
has access to a better model, or could explain how to correct this one?
Thanks.

  Disregard - I'm not sure what I did wrong but the circuit now has its
output sitting at approximately the correct voltage.  User error.
