First check DC if its stable.
To check AC ripple you need a oscilloscope.
Preamplifier PSU, you can check with DVM.

Then the secondary filter caps you are referring to the caps OTHER than the 6 main filter caps just outside the cage?

This response, I don't understand. There are 6 same size filter caps adjacent to the case. I am assuming those are what you are calling the main filter caps. So then are you saying that any other electrolytic caps are the secondary caps?

Thanks.

On top filtercaps, and on the right side of transformer voltageregulators.

So those are the secondary caps you are referring to. I found 3 caps on that board that have high ESR, one of them I previously mentioned. But you said before that might not be the cause.
