This time, LM386 would be the right guess.  ;) It's tough to know anything based on the description, but it could basically be a pair of 386's in series, like so:

Or it could be just a smokey amp with a single-transistor boost in front.

  LM386.
  Handy chip !
  Built a buncha circuits and little amps with this one.
  It makes a tidy and very rigid voltage divider too, supply a voltage across the V+ and Gnd. and the output is your Vbias.
  This kind of power @9vdc [or even just under it's chip-current/voltage-limit, use heat sink] is a bit 'clunky', and that is a sought after, or less desirable attribute.
  I'm not exactly sure what 'it' is, but the 386 can definitely be caused to distort, drive a speaker to 'loud' with it.
