[Amps] Advanced Power Technologies ARF1505

[mike kendall]

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).
