Good find on those dried out caps there Chris. The internet is your friend when looking for unusual caps like you have in that chassis. AES, Digikey, Mouser, All Electronics, Fair Radio, Surplus Sales of Nebraska, and others I'm brainfarting about right now. Also there might be a yayhoo group dedicated to old Marantz gear. Just remember that electrolytic caps are polarized and will vent or explode if wired in reverse. Put a piece of tape or some other marker like a tie wrap to mark the positive lead. A lot of people have learned this the hard way.
