Chip, To me, that looks like a bit of a ham fisted repair that someone did. As French Marky commented, the solder is a common repair technique, but I think someone used 20 times more solder than should have been required. Before replacing the board, I would try to reheat and suck that solder off the board and attempt to repair it again using about a 1-2 mm drop of solder before smoothing and sanding it flat.
Has anyone tried one of the conductive paint products for this type of repair?
As for the 9 hangup, I've also seen the issue that EMs in KC wrote about, with that switch exerting too much tension such that the reel hangs up.
