1949 Motorola 5A9M
#6

I've started replacing the electrolytic caps now. As Arran mentioned, they are housed under a metal strap. Here's a photo of those caps. There is an 80uF (yellow) and a 40-20-15uF cap (black). To get to them you undo the metal strap and desolder a handful of wires from that wire bundle and the caps themselves. I've got them restuffed and back in the set now.

Now its time for what I think will be the most difficult part. Replacing the caps and resistors in the rest of the set. Its really packed together and I'm not sure how much of it I'm going to be able to access without completely dismantling everything. There is also a selenium diode that will need replacing but I think that should be pretty straight forward.
