Who let the smoke out?

All the smoke was let out of an HP 8656A RF generator, and I’m currently in the process of trying to get it back into the box.  This picture is of J5 on the A10 power supply board where the most significant damage is.

This next photo is the underside of the A10 board near the J5 connector.  It’s interesting to note that at the topside Pin 1 (GND) had the melted wire while on the bottom of the board Pin 2 (+5V) has the crispy trace.
