اخواني الاعزاء ........يلزمني بعض القطع الالكترونية هل من الممكن اناجدها عندكمQ3 2N3819 or 2SK30A(Check PINOUT, Before Installing)
Q4 2N4125 or 2N3906 or almost any PNP type signal transistor will work.
D1 1N4937 "High Speed diode."
D2 1N4937 "High Speed diode."
IC2 LT1054-CN8 -(8 pin dip) "Substitute a ICL7660ACPA", it is much cheaper)
ICL7660.....SEE NOTE AT BOTTOM!
IC3 78L05 T0-92 pkg.
IC4 79L05 T0-92 pkg.
C2 4.7 to 10 uF Tant. @ 10 Volts Min.
