Id say that those handfull of components would be a waste of time anyhow, looking at your pics the corrosion has affected the metal so you would need a lot of the components and sockets etc replaced, its basically beyond economical repair, salute you for trying to repair but you will end up chasing your tail wondering if you have badly soldered a component you have replaced or if its an other component further along that needs replaced etc
Id just bite the bullet and get a new board, probably be cheaper than replacing all that needs replaced anyhow. I have an alltek board you could get a loan of (or buy if you prefer)
Think you are fairly near to me?
