Hi,
I want to change this capacitor and can't find it new.
Could you please help me to know where I could find it?
Thanks, best regards,
Julien

If the cap has 4 legs for only one capacitor, it is a good idea to replace with a similar unit in case the PCB layout is depending on the extra leads to jumper between two lands and parse PS current flows. 

If you can't find the exact same cap, replace with the same value and check the PCB layout for any extra connections that may be needed. If you have two leads and four holes it could make a difference which holes you use.

PS: Have you talked to the manufacturer of the product about service parts?
 
Thanks guys
They seems to be here since 1990 and the top of one is not flat anymore, so I prefer put new things here!
I asked them about this but tried here as well

Hey! thanks Milan!
It does not matter the original one is rated -10/+30% and the one you proposed (4700uf/63v) is -20/20%?
 
Hi,
the capacitance tolerance of+-20% will be more than enough.
More info you can find here:
