    Does anybody know of a schematic for an amplitude modulated amplifier?
    Yes, I do mean *amplifier.*

    Way too unspecific. Microwatts or megawatts? Audio? RF? What's
    your objective?

    Find a copy of the Radio Amateur's Handbook. You should find a
    plethora of schematics and general information on amplitude modulation
    techniques.

    ** See any guitar amp schem that has a " vibrato " effect circuit included.

    Fender, Music Man, Dynacord, Goldentone ......

    A while back I made a sonic screwdriver for my nephew who was, is, a
    big Doctor Who fan. It used frequency modulated sound to turn screws.
    But at 143 dB it was too loud and people complained when he played
    with it. So I decided to redesign it, use amplitude modulated
    ultrasound which is still loud, but so directional nobody can complain
    about it. I figure it would be easier to amplitude modulate an [audio]
    amplifier than an ultrasound oscillator.

    To turn screws? Really? How well did it work?
