Unfading Faded wood

[Doki]

I've got a set of 70s speakers that have obviously been near a window, and thus are faded quite badly. They've got a rosewood veneer on them, and I'd like to sort it out. Any ideas on how to get the colour back, and fill a couple of scratches?

Can I suggest you try the appropriate forum on this website as this may be too specialist a question for this Usergroup.
