Upgrade caps in power supply?

[Ptsss]

I have a preamp from the 90's that has a large separate power supply (ps) with 80 volt output. Preamp works fine. Is there any benefit by renewing/upgrading caps in the ps?

Impossible to say without more info on what it is etc. Schematic?

Thanks Jeff. I don't have a schematic. It's part of a Spectral DMC20 preamplifier. A google of Spectral Audio DMC20 will simply bring up pictures. The company does not release schematics. This was a exceptional unit when manufactured. It has a faulty relay now and I'm wondering if I can/should upgrade anything while doing that repair.

I would replace the relay first, and verify all works well first.
Then see if good replacement capacitors are available that will fit the board properly.

Thanks Rayman. Those will be my instructions

Spellchecker error. Sorry rayma.

If you replace a lot of stuff all at once, and then it doesn't work, you don't know what went wrong.

Yes
