I know this is an old thread, but I have 2 boards with similar issues. On the original factory board, the capacitor spewed electrolyte over literally half the board. Multiple traces in that area were completely corroded away. I'm thinking that board is a loss. I then bought another board from someone who reported the head turns one way but not the other. I checked it over and found the cap had also leaked (what's the deal with that anyway?), but it was in a very contained area. On this board, there is minor corrosion on U1 and a few resistor pads. I removed the bad cap, scrubbed with board with alcohol, and replaced the cap. I installed the board and still see only counter clockwise works and not clockwise.

I didn't find any shorts on the TIP102s and TIP107s. Because U1 has corrosion, should I replace it as well?
