I am not smart enough to understand how the common ' tank circut ' works as used in LC oscillators. The current first flows through the cap then through the inductor because caps allow immediate current flow and inductors resist it I know, but I'm buggered if I'll ever understand how the transistor switching circut 'knows' when to kick it the other way.
Many of you will in aus.electronics will have designed hundreds of such circuts and understand precisly how they work. I admire you !
I hope the light bulb above my head starts attracting moths soon.
