Hello fergo and welcome to the DigiKey TechForum.
I would think that the capacitors marked 47 6A 53B would be an option similar to the 47uF capacitors linked HERE. Assuming that 47 is the capacitance, 6A for voltage and maybe series, and 53B for date, lot, or internal marking. Selected 6.3V as we did not have any that were rated for exactly 6V.
For the one marked 10 16A, I would think one of the options linked HERE could work based on the same assumptions listed above. It appears that the Panasonic options do use the Capacitance/Voltage/Date code marking structure.
