    Beg pardon, my friend; not my circuit. It is a generic redrawing of Roger's original circuit. Which transistors did you use? And did you toast them?

    Thanks for the drawing! It illustrates the problem very nicely! (The red current path is through two diode junctions.)

    "Easy to use" is easy to say.
