Thanks for writting I will check out your suggestionson where to buy power supplies (I didn't even think of e-bay being a place for such things).
I am designing / looking for several circuits (with my OLD degree in elect. eng. I say that because alot of what is said today is "almost" beyond me).
I am designing / making a prototype of a "machine" that needs several simple circuits (individual voltage supplies), and a few complex circuits (MHz frequency modulation) to run some transducers.
At this point, I am not sure what voltages I will need but, I know I will need a couple anyway. The current output, as I said before will be very low, under 10W, probably under 5Watts.
