Thanks PSW.Circuit because I did not know, with pickup device can replace DRIVE? I made a one-day experiment, but without success.

yes - who designed this PCB layout ? (just shows you, shouldn't trust anything you find on the web ) Col BUT I ambiguity 9V battery build in what about? excuse me! My english isn't good enough Pin 6 on the LM386 should go to +9v (battery +) pins 3 and 4 should go to earth/0v (battery -) so there would be a short in that pcb (with the switch on). Col thank you,I goto chance.hope IT OK. S2 closed circuit,equality 9V + - connexity(short circuit)?
