It would be certain to garner more interest than the ongoing house wiring seminar.

  They are supposed to use the same copper heat spreader and aluminum heat sink that the Motorola applications notes use
and available from CCI (Communications Concepts Incorporated).
>    The company also claims the power supply would be cheaper to build because of no need for a DC to DC converter as
> used in the 48VDC switching power supplies.
>    These FET's are used with the medical applications and HF amplifiers.  They work class A-E up to 30mhz and have a
> typical efficiency up to 75%
>    I emailed the company for more info. and am waiting for a reply.  Comments/discussion?
