Andrew - I'm seeing exactly what you describe. The "corner's cut" are increasingly of a poor standard. I recall one "service department" using Soldering Irons that were better suited to Car battery terminals ! I'm glad you are bringing this to our attention as I have my own "Rogue Gallery" of attempted repairs which have caused MORE problems than the original !
I'm keen to see the boards after you have weaved your magic. I believe this is the standard pinball enthusiasts should be expecting.
