welcome to our forum!
You find the schematics for the PDS5550 in this post:viewtopic.php?f=8&t=2019&p=12484&hilit=pds550#p12484
The right picture shows the power supply board.
IMHO anyone who repairs electronic stuff as a professional should be able to read the schematics and thus see what capacitors to use. Still, it is not guaranteed that a simple exchange of elcaps will make your record player work again. You or somebody'll have to look out for the cause that made the fuse blow.
The thread about wiring the PS550 arm should be this one:viewtopic.php?f=7&t=4247&hilit=kabel+tonarm
I hope you'll understand all the help and hints.
