(I hope this isn't a double-post, but I had an error when I last submitted this)
Stage 1 is complete. All the old caps have been removed and the board cleaned up.
This might help someone else doing this job, I found that I could use a Side Cutter tool
to clip two of the ground the leads off of each capacitor, making it only necessary to
desolder 2 leads to remove them. Did all the work with my Chem-Wik and 40W soldering iron.
Now to add in the ground lead connections and new caps...
