I will assume you are referring to the two large 10,000uf 75v filter caps. They are high quality parts that should last a long time.

Those almost never fail, what is your need.

When I power the amp on it makes a humming noise then trips breaker...seems that the noise is coming
from the area of the items you identified...know a little about tube amps but short on knowledge of
S/state. Thank you for the help! Jerry

After reading some of the post on this forum I realize that my understand of this amp(CS800X) is
very limited. So with that said I believe I will just clean it real good(very dirty) and take it to
a repair shop. Unless there is an easy fix for tripped breaker at power on I am lost. I have 12 of these amps
so would it make sense to swap out parts until problem is found or would I be taking a risk
of damaging a good part? I'm retired so have the time to explorer ideas!! Thanks to all who respond!!

No, swapping parts at random would just likely burn out more parts.

The noise you are hearing is probably the transformer itself protesting. Most likely cause of the breaker tripping is a blown output stage on one channel. That will involve one or more of the power transistors being shorted as well as possible damaged or failed resistors. Yes, you should take it to a qualified repair technician.
