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
