Default Info of Relays

Hi everyone,

Hope this is the right forum to ask this.
I have a power supply from a very big audio amplifier which is 20+ years old.
I want to replace the relays in it.
Firstly, should I bother? Are relays reliable and should work for much more than 20 years?
If I should replace it as a precaution, please help me identify what the relays are.

There are 3 relays, 1 x black and 2 x white.

The white ones say 'FKD130P' which from a website tells me it's equivalent to NTE R53-1D30-24. If this is the case, then that's easy enough to get.

The black on however has only 'Potter & Brumfield T90 Series' on it. How can I tell what model this is or what a suitable replacement would be?

TIA

Sorry, I forgot to mention that.
This is for a Genesis V amplifier. I believe the same model amplifier was used for multiple Genesis systems.

The Genesis speakers had active servo subs in them, and this was the amplifier which drove them.

I would not replace the relays as a preventive maintenance as they are used very little in an amplifier so they should last a very long time.
