i made the above circuit, but in place on 2n3819, i used bf245(this is also a N channel JFET).
i bought two sets of transistors, used both, one by one, sure that both of them cannot be damaged, yet it didnt work. i connected my galvanometer in place of the led, still, it showed no deflection when i bought near the comb........any solution?
