[QUOTE="Nchebe, post: 954251, member: 22015"] Ah, OK I see what your tech guy did. If it was the MC3386/MC3346/CA3086 he replaced with discrete transistors, then all is good. This chip is 5 transistors conveniently packaged for you. You could use 5 general purpose npn trannies (BC308, BC327, 2N2222, etc.) and wire them up according to the configuration of the IC. Just make sure voltage and current capability of discrete is same or higher. Not sure how substrate connection on pin 13 will affect the array of transistors vs discrete transistors - shouldn't be an issue though... [/QUOTE]
