replacing 5 volt regulator on stern freefall pinball driver board
hi, I am replacing the 5 volt regulator on a stern Freefall pinball driver/power supply board. i am replacing a regulator UA78Ho5SC with a LM323K. i had to look up the pin out on the data sheet and noticed ,they are mirror images. long story short, I can line up the pins of the regulator correctly but the heat sink and pcb mounting holes will not line up. I tried rotating the heat sink. Still the mounting holes will not line up. I would appreciate any suggestions.
Thanks
