Even though it's no picnic, you will almost certainly want to replace those capacitors for the set to perform well.

I'm sure there's lots more info on this set to be found. The search functionality built-into the Phorum doesn't always do as well as Google so you may want to google search limiting results to this site:

Remember to go slow and take lots of pictures as you go.
