Alinco DR-635 Pre Amp Repair

I came across a DR-635 that was dead.  After removing the panels it was clear that the pre amp IC had failed.  Note that the heatsink comes out of the board thru a slot for cleanup.  Below are pictures of the repair.  I used solder paste and a hot air station to repair the unit after initial trace and PCB repair using superglue (Don't breath fumes).  Parts were purchased from Alinco.
