hi, i have a busted voltage reg. unfortunately, no replacement can be found here in Yemen so i decided to take a look inside. I found it to be a transistor TIP 102. I tried to figure out how it was built but i destroyed the pcb and other parts in the process of removing the plastic covering that is so thick. Can anyone help me how to build this regulator? It's for an alternator supplying 27v for charging 2 pcs of 12v acid lead batteries. I'm sure my boss will give me a raise if I can accomplish this. thanks.
