I had LC Mac that was Dust Bunny Invaded while in storage, but it tuned on fine. Or so it seemed. The Caps did leaked, but the Dust Bunnies soaked up the electrolyte before it went further on the board to do damage. Cleaned it up, replaced the caps, and it worked better than before the recap.
When I washed the board, it looked fine, but the damage was minimal. It was when I removed the caps did I see the traces begin to rot on the pads the caps were on. No doubt you will see the same thing when you recap the board. Doing this, you are not doing "preventative measures" but an actual repair.
So RECAP THAT BOARD NOW!!!
