Hi Jeff,
   I looked those up on the web.  They have the schematics on their
website!   

  The thing might be useable as a re-modulator in an envelope restored
Class D,E or F amp.

  Incidently, I believe the QSC's are Class G -- switched power rails at
higher output levels.   There is some confusion about (the world) between
that mode and Class H -- power rails that track the input signal.   

  I have used a few switchers for amplifier power supplies... they are
way more work than the amplifier itself.

73 & Good morning,
   Marv  WC6W
