Agreed...resolder the entire sweep circuit , whether they look good or not.
Recently I have purchased a magnifying headset from MCM # 22-7810 ( Page 538
in their current catalog) for $9.......with these you can easily resolder
ALL connections and actually see precisely what you are doing hands free!
Makes resoldering dense areas easy.....
