Is there a work-around to hardwire in a power source properly?

Is there a work-around to hardwire in a power source properly?

The main power-in port on the auxiliary board has broke again. Seeing that the auxiliary boards are hard to come by, I’d like to by-pass the port. A new port cannot be soldered onto this board again. In fact, the board is also missing whatever J2 is (besides the point..).
