I have found ,for bicycles of my niece , schematic of a typical kojak siren but without list of components . I thought of finding , by experiment , the close frequency and getting the just values of resistences and capacitors but I cannot well get them ; does anyone , that bought the kit kemo or similar one , know them ? The scheme is here :
These are my tried values :
R1=R4=R7=R10=R5== 560 OHM R2=r3=R8= R6=r9= 22000 , 2200 ,33000 ,68000
c5=c6 = 22 nano F
C2=C3= 47 micro F
Transistors =bc547 c & bd242
