    I know I am, probably, reinventing the wheel but I am trying to build
    a switching power supply. To some extend this is both an educational
    venture and a practical project for me. I help me with me venture, I
    am using the parts from a older model.

    What I need are a schematic drawing, or block diagram, for a more
    current model. and some information... I know that a switching power
    supply requires a kicker oscillator and power supply to activate this
    oscillator. I have seem a schematic a year or so ago but have
    forgotten some key pieces of information..

    First: What kind of power supply is used to power the kicker? and the
    over all circuit untill the power supply can supply that power.
