Default Sick Carver M-1.0t amp: bad caps?

My Carver M-1.0t amp stopped working and my voltage is screwy. On TP5 and TP6 I should be getting 100VDC. My readings vary, sometimes I only get 40VDC and other times I will get any where from 70-90VDC and then it will begin to fall but never go below 40VDC.

A shorted triac was replaced not too long ago and my diodes on the PS board all look good. I'm thinking the caps are going bad, any other possibilities?

After putting it on a shelf I finally got back to it. Turns out the trim pot that adjusts the voltage was dirty. I cleaned it out with some deoxit and my voltage returned to normal. Thought I'd post the results in case someone ever has the same problem. Sounds great, thanks.
