The 7815 is also defective.

The one thats in the amp is marked Kia 7815A And the package style is where you dont need mica insulators behind it But the regulator is standing straight up in the middle of the board.

I have the following parts 7815act and a LM7815AC both T0 220 package will either of thoose work?
