Have you removed it from the rig yet?
Drill out the pop rivets and remove the four screws holding the PCB in place replace the caps and rebuild the current sense resister network - it's a really simple job - all you will need is a small drill, #2 Phillips screw driver, soldering iron and the replacement parts.
Should not take more than 20 or 30 minutes and cost less than $5.00 for the entire repair.
