ovinewar,
If you haven't download a service manual, here is one:

viridian already give you some excellent advise, I just like to add some of my personal experience working on vintage gears:
Frist step is power up the amp by using a variac or dim bulb tester as viridian suggested, if the amp is working, then go ahead to re-cap. you can use higher voltage rating capacitor but not lower.
Take some picture before you do anything, recap one channel first, test it make sure it is working then recap the other channel.
